6 Winscribe Dragon Speech Recognition Guide About this Guide This guide describes how to install, configure and use Winscribe Speech Recognition. client and server speech recognition. It covers both Other Documentation For further information about Winscribe, consult the following documentation: Winscribe Installation Guide Winscribe Client, Winscribe Author, Internet Author, and Internet Importer User Guides Winscribe Exporter Guide Winscribe Telephony Manager Guide Winscribe Web Manager Guide Winscribe License Server Installation and User Guide Before using Winscribe, please check the release notes for the latest information. Who should read this manual? This manual is written with the assumption that you are already familiar with Microsoft Windows Systems Administration and is written for those who will install, configure and use Winscribe speech recognition. 6

7 Speech Recognition Overview Speech Recognition Overview Features of Winscribe Speech Recognition are: Authors can dictate from any standard telephone or specialist dictation device. Authors can share global commands. Correction can be done using a word processor (Microsoft Word 97 and higher). Winscribe speech recognition fully supports the Author-Typist working method. The author can concentrate on dictating. The typist will do any corrections, formatting and filing, but will be able to work much faster. Multi language support. With Winscribe speech recognition integration you can dictate in several languages, including English US, English UK, French, German and Dutch. Professional topics (vocabularies) are available with common terms and abbreviations for your particular business requirements. Winscribe offers flexibility in how speech recognition is processed. You can run: Client speech recognition Server speech recognition Both client and server speech recognition Running Client Speech Recognition With client speech recognition, Dragon NaturallySpeaking is installed locally on your client PC. You can choose whether or not to run speech recognition processing for each job. If you choose to run speech recognition processing, it runs while the job is being dictated and you can edit the speech recognition text, if desired, during the dictation process. Features of Client Speech Recognition are: Speech recognition text can be viewed, edited and corrected while the job is being dictated. Training can be run by an author on their local machine, and new words added to the author's vocabulary as jobs are dictated. Acoustic adaptation is not run. Running Server Speech Recognition With server speech recognition, Dragon NaturallySpeaking is installed on the speech recognition server, and all Winscribe speech recognition jobs are sent to the speech recognition server for processing. Acoustic adaptation can be set up to run automatically on the server for matched text-audio pairs. Calculating the Number of SR Servers Required Average Audio Length The average length of the audio recorded measured in seconds, averaged across all jobs for a day. This is typically somewhere in the order of 300 seconds (i.e. 5 minutes). Server Processing rate This depends on the processing power of the server. In our experience, a typical server will process audio and recognize the speech inside it in around 15 minutes for a 10 minute recording (i.e. a processing rate around 1.5 times the average recording duration). 7

8 Winscribe Dragon Speech Recognition Guide Maximum Number of Jobs per day This can vary day to day, but to be conservative, use a number that is on the high side. This effectively states how many jobs your SR Servers will be able to process. If this is lower than the number of jobs you actually have, the jobs will build up over time and create a backlog. Number of servers required The number of servers required is a simple function: As an example, if we have 203 authors with an average of 5 jobs per day each, we have 1015 jobs per day. Each recording is 5 minutes on average and the server takes 1.5 times the audio length to process the jobs. To process 1015 jobs, we need 1015/192 Servers = 5.3 servers (which rounds up to 6 Servers). Six servers can process, at most, 192 * 6 = 1152 jobs per day if there are busier days, the server will encounter a backlog. To avoid a backlog, it is important to use a sensible maximum for the number of jobs per day, rather than just an average number. When faster turnaround is required The calculation above assumes you are happy with an average server turnaround of 24 hours per job. If you instead want an average server turnaround of 1 hour, the equation looks as follows: If we assume an author works an 8 hour day, and has the same 203 authors with 5 jobs each, we have 1015 jobs per day, divided over 8 hours is 127 jobs per hour. So, to process a total of 127 jobs per hour with each server only able to process 8, you would need 127/8 = 16 servers. These equations can be made to work with any unit of time, however the turnaround time is ultimately limited by the length of the audio and the availability of the server. If you want an even faster turnaround time, you can use the Erlang C Formula following to calculate the average wait times. Queuing Theory, an area of computer science, provides systems administrators with the Erlang C Formula, which can be applied when calculating the number of Speech Recognition servers required. 8

9 Speech Recognition Overview The Erlang C Formula is used primarily by telephony engineers (phone systems are queues), as it allows for items queuing up with an indefinite waiting time (i.e. they don t disappear or give up) a model best suited to jobs waiting to be recognized. Erlang C Formula The Erlang C formula expresses the waiting probability in a queuing system. A is the total traffic offered in units of erlangs N is the number of servers PW is the probability that a customer has to wait for service Online Calculators To assist in calculations, there are several online calculators available for working this formula, e.g. : Note: Calls can be considered synonymous with Dictation Jobs. Example Calculation Calls per hour 127 Our example site has 203 authors with an average of 5 jobs per day, which works out to 1015 jobs a day, or per hour. Assuming an 8 hour work day and we are interested in the SR response time during this period. Call duration 450 Statistics in our example site indicate that the Dragon processing time is around 1.5:1. So, on average, a 5 minute job will take 7.5 minutes (or 450 seconds) to recognize. Avge. delay 600 This is the queue wait time. This is set to the maximum the calculator can handle (10 minutes = 600s). Note: this wait time is added to the processing time, so a 5 minute job may take minutes = 17.5 minutes to process. Entering the above variables returns the number of agents (servers) required (per hour) as 17. 9

10 Winscribe Dragon Speech Recognition Guide Running Both Client and Server Speech Recognition If running both client and server speech recognition, Dragon NaturallySpeaking is installed locally on your client PC and you can choose for each job whether to process speech recognition locally. If speech recognition has not been processed locally, the system will automatically submit the job for speech recognition on the server. This option has the added advantage that a user can log into any machine, whether it is running Dragon locally or not, and choose to send jobs for speech recognition. 10

11 Configuring both Client and Server Speech Recognition Configuring both Client and Server Speech Recognition There are several configuration options that can be used for both client and server speech recognition. Read this section if you are running either of these, or both together. Licensing Speech Recognition In order to run client or server speech recognition, a Winscribe license must be obtained for each author. These licenses are held and managed on the License Server, as detailed in this Guide. Note that Winscribe licenses are identical for both server and client speech recognition. Therefore an author can run both server and client speech recognition using a single Winscribe license. The procedure for licensing both client and server speech recognition is detailed under Step 8: Add Speech Recognition Licenses (see page 54). The same licenses are used for both client and server speech recognition, so the procedure to install is identical. If running server speech recognition, you can allocate, configure, and monitor your speech recognition licenses using the procedures detailed under Configuring Server Speech Recognition (see page 99). If running client speech recognition, you can configure the license server as detailed in the License Server Configuration for Client and Server Speech Recognition section of this document. For client speech recognition you do not need to manually reserve licenses. Switching client speech recognition on for an author (in the Winscribe Author Options window) will automatically allocate a license for that user. Similarly, switching client speech recognition off will release the license. Upgrading Licenses Winscribe speech recognition licenses are version-specific. For example, if you are running version Winscribe version 3.8 and you wish to upgrade to version 4.2, you will also need to upgrade your speech recognition licenses. The Winscribe Help Desk will be able to assist you with this. Pre-requisites for Running Speech Recognition Use of Winscribe V4.2 client or server speech recognition requires Nuance Dragon Naturally Speaking version 11, 11.5, 12, or 12.5 to be installed. This can be purchased from a Winscribe Reseller. Speaker Profiles A speaker profile holds all information for an author, such as their context and vocabulary. Speaker profiles are created as follows: 1. When a new user logs in for speech recognition processing, the Winscribe License Server application checks for an available speech recognition license. 2. If a license is available, the Winscribe system checks for an existing speaker profiles directory. 3. If the speaker profiles directory does not already exist (this is the first speech recognition job to be processed), the directory will be automatically created, as follows: If processing a server speech recognition job, a roaming speaker profiles directory is created. 11

12 Winscribe Dragon Speech Recognition Guide If processing a client speech recognition job, a local speaker profile directory is created on the user's machine unless the location of the Speaker Profiles Directory is specified in the Winscribe WEB Server Settings window. If the location of the roaming speaker profiles directory is specified, the same speaker profiles will be used for both client and server speech recognition. 4. A new speech recognition user name is automatically created in the Speaker Profiles directory. The username is: SystemID_FacilityID_UserID. 5. A speaker profile is automatically created for the user and stored in the Speaker Profiles directory. The Roaming Speaker Profiles Directory You must enter the location of the Speaker Profiles Directory into the Winscribe Web Server Settings window if you: Will be using both client and server speech recognition. A default speaker profiles directory is automatically created by the system when the first speech recognition job is processed. If processing a client speech recognition job, a local speaker profile directory is created on the user's machine unless the location of the Speaker Profiles Directory is specified in the Winscribe WEB Server Settings window. If the location of the roaming speaker profiles directory is specified, the same speaker profiles will be used for both client and server speech recognition. Note: Defining the speaker profile path after Winscribe has created local speaker profiles will result in Winscribe creating brand new speaker profiles at the remote location. (Local speaker profiles are created when a client speech recognition job is processed and a roaming speaker profiles directory has not been specified in the Winscribe Web Server Settings window). Specifying the Speaker Profiles Directory Path in the Winscribe WEB Server Settings Window 1. Log in to Winscribe Web Server Settings using the Winscribe Systems Administrator user id and password. 2. In the Speaker Profile field enter the path to the speaker profiles directory on the server, or click on the button next to the field to browse to the required directory. 3. Click OK. 4. If adding the Speaker Profile path after Web Manager has been installed, you will need to manually restart IIS on the server where Web Manager is installed. To do this, click on the server's Start menu and select Run, then type in iisreset. 12

13 Configuring both Client and Server Speech Recognition When you click OK, IIS will restart. This may take a few minutes to complete. Deleting a Speaker Profile Use the following procedure to delete a speaker profile that is no longer required: 1. Close the Winscribe Author application and Dragon NaturallySpeaking (if running). 2. Release the license for the author as follows: Point your web browser to the Winscribe License Server: Click on the Release Licenses menu item at the top of the page (you may be prompted to log in to the license server). Select the profile to release and click the Release link. 3. Delete the speaker profile from: The Speaker Profiles share directory on the Dictation Server. The following directory on the server on which Dragon is installed: C:\Documents and Settings\All Users\Application Data\Nuance\NaturallySpeaking9\Users The following directory on the Author's Local machine: C:\Documents and Settings\All Users\Application Data\Nuance\NaturallySpeaking9\Users 4. Restart the Winscribe Adapter service by browsing to the following URL selecting the Adapter Service and changing the status. 5. Run IISRESET (by typing in IISRESET on the Run window accessed from the Start menu in Windows) on the server where the web server runs. (This will usually be the Dictation Server). Dictating with Speech Recognition For good results when using speech recognition, you must ensure your audio recordings are of the best possible quality. Use the following procedures to correctly set the volume and audio format. Set the Correct Volume For accurate server speech recognition, it is important that the volume levels are set correctly when authors record their dictation. In the Playback Tab on the Options window in Winscribe Author, set the Microphone slider to its lowest setting and the Volume slider to its highest setting. Refer to Step 18: Set Server Speech Recognition Volume Control (see page 81) for more details. Set Audio Format to Highest Quality When running speech recognition, you must ensure your audio format is set to the highest quality. If the audio format is not specified for the author recording speech recognition, it will default to the audio format used by the facility. Use Winscribe Web Manager to set the audio format for each author that will run speech recognition. Setting Audio Format in Web Manager 1. Open Winscribe Web Manager and log in. 2. Click on the Users menu, point to Authors and then select the Update option. This opens the Authors window. 3. Click on the required Author ID to open the Update Author window for that author. 13

14 Winscribe Dragon Speech Recognition Guide 4. In the Miscellaneous section of the window, click on the Audio Format drop down box and select SPEEX High (the highest quality audio format available). Set the Registry Setting for the DNS 'Capture All Dictation' Option In the system registry, there is a switch entitled 'Capture All Dictation'. This setting exists in: HKEY_CURRENT_USER\Software\Winscribe\General\CaptureAllDictation When changing this setting it must be updated. This switch is set to FALSE by default. Setting it to TRUE means that it will record all dictation. It will preserve all audio including unrecognized utterances, any pauses or periods of silence, filler speech like 'ums' and 'ahs', extraneous noises, and anything else the speaker may do, like cough or laugh. Having this switch set to TRUE will ensure that the audio file remains intact and unrecognized words are not removed from the voice recording. The typist can then review the complete audio file and ensure that the transcription is completely correct. Note: If this switch is set to TRUE, the only utterances that will not be recorded are voice commands for editing text. Voice commands such as 'Select' or 'Scratch That' will be recorded as silence. Therefore if you spend five minutes using voice commands to edit your text, there will be five minutes of silence recorded on your audio file. If this switch is set to FALSE, unrecognized words and pauses will be removed from the audio file, truncating the file accordingly. Setting up Authors for Both Client and Server Speech Recognition in Winscribe Use the following procedure to set up authors who will be using both client and server speech recognition. Step 1: Specify the Location of Speaker Profiles Specify the location of the speaker profiles (see page 12). Step 2: Set up Authors and Job Types for Server Speech Recognition 1. Create your required Winscribe Author profiles in Winscribe 2. Server Speech Recognition for those users who will use it 3. Give profile language 4. Add topic to Dept/Job Type 5. Enable Speech Recognition on job Detailed instructions are provided in Setting Up Server Speech Recognition for Job Types, Authors and Typists (see page 96). 14

15 Configuring both Client and Server Speech Recognition 1. Step 3: Set up Authors for Client Speech Recognition 1. Ensure Winscribe Author and Dragon NaturallySpeaking have been installed on the Author's client machine. 2. Start Winscribe Author and check the Author's speech recognition settings by selecting Options from the Tools menu to open the Options window, then clicking on the Speech Recognition tab, as shown below. 3. To turn on client speech recognition, select Dragon from the Engine drop-down list and tick the Use Immediate Foreground Recognition checkbox. 4. If the Always Display Recognized Text checkbox is ticked, the author will always use client speech recognition and will not be able to use server speech recognition. Step 4: Create a Server Speech Recognition Job 1. Create and complete a Winscribe job using a server speech recognition job type. This will allocate a server speech recognition license and automatically create a speaker profiles directory. 2. Ensure speech recognition processing has completed correctly. You will be able to tell by checking the speech recognition icon displayed next to the job. A lined page icon indicates speech recognition processing has been completed and the job is ready for transcription. A blank page icon indicates the speech recognition process is still being run, and the text is not yet available. If, after waiting a few minutes, the page icon does not change from a black icon to a lined icon, there may be a problem with your server speech recognition process. In this case, refer to the Troubleshooting Speech Recognition Operation section at the back of this guide for assistance. Step 5: Create a Client Speech Recognition Job and Complete New User Training Warning: Only start this procedure when the Author has time to complete the entire procedure in one go (it will take several minutes to complete). 15

16 Winscribe Dragon Speech Recognition Guide 1. Create a new Winscribe job and turn on Client Speech Recognition by clicking the Speech Recognition button on the toolbar before starting to dictate. Dragon NaturallySpeaking will start automatically and all normal Dragon functionality will be available using the Winscribe Author menu. 2. You will be prompted to confirm that you wish to create a new Winscribe Speech Recognition user, and to select the base language and vocabulary to use. You will then be prompted to select an audio input device for use. 3. The New User Wizard will run. Complete all steps in the wizard as prompted. Step 6: Create Custom Vocabularies Add words to the main vocabulary and/or create new custom vocabularies using the procedures detailed in the Working with Vocabularies (Contexts) (see page 113). Step 7: Set General Options for Client Speech Recognition Note: The Author must have completed New User Training before setting the following options. From the Speech Recognition menu in Winscribe Author, select General Options. This opens the Options window as shown below. Ensure that for each tab, the checkboxes ticked are the same as those shown in the screenshot.

19 Configuring both Client and Server Speech Recognition Text-to-Speech Tab Change nothing on this tab. 19

20 Winscribe Dragon Speech Recognition Guide Configuring Winscribe Client Speech Recognition If you are running client speech recognition, use the following section to configure your system. Working Off Line with Client Speech Recognition If a user is completely disconnected from the server, they will not be able to use client speech recognition. An error message will be displayed if they attempt it. If an author wishes to use client speech recognition and work offline (by pressing F3 in Winscribe to disconnect Winscribe from the server), they can do this as long as: The computer they are using remains connected to the server, and Their speaker profiles directory setting is blank. (Refer to the Setting Up a Speaker Profiles Directory section, above). Dragon logging By default, logging is set to FALSE. When set to TRUE, the Winscribe Author creates and appends to a text file called wsidragon.log on the PC for every speech recognition job that is done. To turn this default logging ON go to: HKEY_CURRENT_USER\Software\Winscribe\General and set the DragonLogging key to TRUE. Client Speech Recognition Workflow Summary The following process flow diagram shows the global commands, macros and templating features available within Winscribe Author when using client speech recognition, and the steps taken when using them. Note that the steps in this process flow are optional. That is, it is not necessary to create or use global commands, macros, or templates when using Winscribe client speech recognition. These options do, however, provide powerful functionality that can be used to enhance speech recognition processes. 20

22 Winscribe Dragon Speech Recognition Guide Setting Up Dragon Global Commands Dragon Global Commands are processed during the dictation of a client speech recognition job. should not be confused with Winscribe Global Commands which are processed after a typist has corrected the job. They Purpose: To insert an.rtf document or a block of text into a dictation. If inserting an.rtf document, it can be used as a template to format the dictation. The.rtf document or text can contain [prompt] fields denoted by the use of square brackets around the field name. These fields can be selected by the author using voice commands, and replaced with text. Operation: After creating a new speech recognition job in Winscribe Author, the author speaks the defined Global Command and a block of formatted text including [prompt] fields is inserted into the Recognized Text Pane. The Author can then issue voice commands to select the [prompt] fields, in order to replace these fields with text. Example Set up a Global Command to insert the following form into a dictation, prompting the author to fill in the form fields. Patient MRN Number: [MRN] Patient Name: [PatientName] Patient DOB: [DOB] Creating Dragon Global Commands Create Global Commands using the Dragon Command Browser window. This can be accessed by selecting Accuracy Center from the Speech Recognition menu, then selecting Launch the Command Browser. For further information, consult the Nuance Dragon User Documentation. Setup Methods Global Commands can either insert a block of text or an rtf file, as follows: 22

23 Configuring Winscribe Client Speech Recognition Method One: Create an.rtf file containing the [prompt] fields using WordPad, as shown in the screenshot below. Note that this file must be created using WordPad, and not with any other text editor. Ensure that you save this file with an.rtf file extension. Then create a Global Command to load the.rtf file, as shown in the screenshot below. The Global Command should be in the following format: [LOAD_RTF=C:\Templates\Patient Details.rtf] When the Global Command is spoken, the contents of the.rtf file will be displayed in the Recognized Text Pane in Winscribe Author. 23

24 Winscribe Dragon Speech Recognition Guide Method 2: Create a Global Command to insert a block of text containing the required [prompt] fields, as shown in the screenshot below. When the Global Command is spoken, the text entered into the Global Command Editor will be displayed in the Recognized Text Pane in Winscribe Author. Using Global Commands Inserting the Text or RTF File into your Dictation Once you have started a new Winscribe job, ensure that you are recording and then speak the voice command specified when the Global Command was set up. Replacing the Fields with Text To highlight the fields inside the square brackets [prompt], use the following commands: First Field Previous Field Next Field Last Field Or you can say the word(s) inside the square brackets followed by the world 'field' to select that field. For example, to select the [Patient Name] field, say "Patient Name Field". Once a field is highlighted, simply speak the required words to replace the field name (including the square brackets) with the word(s) you have spoken. For example, when you have highlighted the Patient Name field, speak the patient's name to insert it. Note: If you use a Global Command to insert text or an RTF file into your dictation, the audio file saved with the job will not include the spoken command. Troubleshooting Global Commands Creating these RTF template files can occasionally result in the Font of the recognized text defaulting to 'Times New Roman' if a table is used in the RTF document. This can be rectified by manually editing the RTF file using Notepad, removing the "Times New Roman" font specified at the top of the RTF file. For example, remove the following text: 24

25 Configuring Winscribe Client Speech Recognition {\f1\froman\fprq2\fcharset0 Times New Roman;} Setting up Microsoft Word Templates and Macros Purpose: This function enables you to utilize the templates, macros and formatting features of Microsoft Word, by copying a Winscribe dictation into Word. Operation: Complete audio dictation within the Winscribe Author application and correct the resulting recognized text in the Recognized Text Pane. Click on the Word button in the Recognized Text Pane toolbar, or use one of the following voice commands: Word File, Word That, Word Processor File, Word Processor That. This opens Microsoft Word and runs the macro associated with the Job Type for the job being dictated. The macro typically creates a new Word document based on a specified template, then extracts data from the job and inserts it into the Word document at the designated bookmarks. Note: This setup step is not related to the previous Global Command setup. Creating a Word Document Once you have completed dictation in Winscribe Author and any required Dragon Global Commands have been run, you can open the dictation inside a Word document by either clicking on the Word icon in the text recognition toolbar, or using one of the following voice commands: Word File Word Processor File Word That Word Processor That (Note that you must be recording in Winscribe Author to use a voice command). This launches Microsoft Word with the correct template (if setup) for the current job type and fills out the bookmark fields that it has information for. If the CorrectedText bookmark has been inserted into the template, the recognized text is pasted into the Word document at that location. If there is no matching template then the 'normal.dot' template is loaded and the recognized text is pasted in. The Word document that opens is created based on the default template for the Department - Job Type. This is specified using the Department Job Type window in the Winscribe Web Manager. The formatting of the text in the Winscribe Author Recognized Text Pane is retained when the text is pasted in to the Word document. 25

26 Winscribe Dragon Speech Recognition Guide The document can contain bookmarks which will be populated with information from the Winscribe Job, such as the key field, the user fields, the recognized text from the Winscribe dictation, etc. For more information on the bookmarks which can be used to insert information from the Winscribe Author application, refer to the Bookmarks section (below). Notes: You should ensure your dictation is complete before creating the Word document. When dictating, you should ensure the focus is on the Winscribe Author application to avoid unintentionally dictating into another text-based application. If the focus is not on Winscribe Author when recording, the audio will not be saved. Any Word Document created using the Word Processor button will not be automatically linked to the Winscribe job, however if required you can manually attach it as detailed above in the Recording a Job section (Step 6. Add or Delete Attachments). Setting up Word Macros Use the Macro facility within Microsoft Word to set up your macro, as shown in the example below. Example Word Macro Sub chestxray() Documents.Add Template:= "C:\Templates\Chest X-Ray.dot", NewTemplate:=False, DocumentType:=0 End Sub Bookmarks Following are the bookmarks in the Winscribe Author application that are used to automatically populate fields in your Word document with information from the Winscribe job. These bookmarks should be inserted into the Word template(s) you will use for client speech recognition. The CorrectedText bookmark inserts the dictated text from the speech recognition pane into the Word document that is created from the template. The other bookmarks in the list insert information from the job header. AuthorName Jobnumber Department Jobtype Notes Key User & [User Field Number] For user fields 1 to 10. For example, for the first user field enter 'User & 1'. Note that although there are 10 user fields, only 5 of these are text fields (the others are voice fields). Only the text fields can be inserted into the Word document using bookmarks. CorrectedText Copying Text from Microsoft Word into Winscribe If required, you can copy corrected, formatted text from Microsoft Word back into the Winscribe Text Recognition pane. However, once text has been manually copied, the link between the text and audio can no longer be retained, therefore the job's audio file will be deleted. This copy and paste functionality is intended for use by authors who wish to perform final correction and formatting of their jobs themselves, rather than using a transcription service. 26

27 Configuring Winscribe Client Speech Recognition Completing Jobs Use one of the following two methods to complete client speech recognition jobs: 1. Speak one of the following voice commands: Not Corrected Job: This will mark the job as not corrected. The job will be sent to the typist queue. The page icon displayed against the job will be white. Partly Corrected Job: This will mark the job as partly corrected. The job will be sent to the typist queue. The page icon displayed against the job in Winscribe Author and Winscribe Typist will be yellow. Fully Corrected Job: This will mark the job as fully corrected. The job will be sent to the typist queue. The page icon displayed against the job in Winscribe Author and Winscribe Typist will be green. Completed Job: This will complete the job. The job will not be sent to the typist queue. (Note that the voice command 'Complete Job' can also be used).

If you are using the Complete Job or Completed Job voice commands, having this checkbox ticked can be a good precaution, as it means you will be prompted to confirm that you do want to complete the job without sending the job to the typist queue for transcription. 27

28 Winscribe Dragon Speech Recognition Guide If the Confirm end job commands check box is ticked, you will be prompted to confirm that the job will not be sent to the typist queue for transcription. The following alert window will be displayed: Click Yes to complete the job without sending it to the typist queue. Click No to cancel the Completed Job command and return to the open job. If the Confirm end jobs commands check box is not ticked, you will not be prompted to confirm the Completed Job or Complete Job command. The job will simply be completed and will not be sent to the typist queue for transcription. Note: The Confirm end jobs commands checkbox controls whether or not you are prompted to confirm the completion of all jobs, including those that do not use speech recognition. Integration with an external Data Store Winscribe can integrate with any external data store to automatically insert data into your Winscribe Jobs, using the Winscribe Database Reader. The Winscribe Database Reader enables you to link a database connection to a Winscribe event. For example, user fields in your Winscribe job header can be automatically populated when a script is run. Important: When integrating with a data store, it is important to remember that the key field in your Winscribe job must match the key field in your database table for the integration to work. In the following example the key field is the Patient Number. The patient number entered ( ) must match a record in your database for the data from your database to be successfully read into your job or Word document. 28

32 Winscribe Dragon Speech Recognition Guide The Winscribe Speech Recognition Event Script The Winscribe Speech Recognition event script is triggered when Winscribe Author detects bracketed fields within the recognized text pane and there is key field information in the job that matches the key field information in the database. In the Dragon Global Commands you can set up fields to be changed by surrounding them with square brackets [ ]. If you are using the Winscribe Database Reader and a Winscribe Speech Recognition event script has been set up to automatically populate these fields, then the text in the square brackets will be replaced with data from your database. For example, after you start a new job and enter the key field, you can speak a Dragon Global Command to populate the specified text into the Recognized Text Pane in Winscribe Author. Refer to the Dragon Global Commands section (above) for details on setting up and using Dragon Global Commands. Example Your Global Command might insert the following form into a dictation. Patient MRN Number: [MRN] Patient Name: [PatientName] Patient DOB: [DOB] The fields in square brackets would be automatically replaced by the actual data from your datastore. Patient MRN Number: Patient Name: Robert Jones Patient DOB: 10/12/2005 Setting up the Winscribe Speech Recognition Event Script Use the following procedure to set up the Winscribe Script: 1. Open the Winscribe Script Editor from the Tools menu in Winscribe Author, or by clicking the Scripts button on the toolbar. 2. In the Program Events field, click on the down arrow and select the Speech Recognition Event. 3. Enter your script into the Script Editor window. Important: When using the wsgetdbinfo COM object from within a Winscribe script you must always call the following two lines before calling GetDBInfo() or else the Winscribe Author will lock up: objp.setauthorid (objauthor.userid) objp.setwindowhandle (objauthor.hwnd) 32

If you are using the Winscribe Database Reader, bookmarks can be added to the template to automatically populate the created Word document with information from your data store. using a Word Macro, as detailed below. Setting up Word Macros to Integrate with your Data Store Use the Macro facility within Microsoft Word to set up your macro. Do this The macro should consist of two parts: The first part opens the template, the second runs after the template is loaded and populates any required fields from the database. This can be seen in the example macro below. Example Word Macro Sub chestxray() Documents.Add Template:= "C:\Templates\Chest X-Ray.dot", NewTemplate:=False, DocumentType:=0 End Sub Sub chestxrayloaded() Set objp = CreateObject("wsGetDBInfo.clsGetInfo") objp.setwebserviceurl (" Database Reader/") MRN = Application.ActiveDocument.Bookmarks("Key").Range.Words(1).Text objp.getdbinfo (MRN) PatientName = CStr(objP.GetFieldInfoByName("FIRSTNAME")) & " " & CStr(objP.GetFieldInfoByName("LASTNAME")) Application.ActiveDocument.Bookmarks("PatientName").Select Selection.InsertAfter PatientName DOB = CStr(objP.GetFieldInfoByName("DATEOFBIRTH")) Application.ActiveDocument.Bookmarks("DOB").Select Selection.InsertAfter DOB End Sub Using Word Macros To insert data into your Word document, insert bookmarks at the required locations, and ensure that your Word Macro uses those same bookmark names. When the Word document is created (by clicking on the Word icon or using one of the following voice commands: Word File, Word That, Word Processor File, Word Processor That), the bookmarks are automatically updated with data from the data store. Example Your document might contain the following bookmarks (shown in bold). Patient MRN Number: MRN 34

36 Winscribe Dragon Speech Recognition Guide Dictating Jobs Using Client Speech Recognition When dictating jobs using client speech recognition, always ensure that speech recognition processing has finished before stopping the recording. When recording a job it is best to pause your speech occasionally to allow the speech recognition process to catch up with your dictation. If you manually stop the recording while speech recognition is still being processed, the last part of the recording may be lost. It is easy to ensure that speech recognition has finished before stopping the recording, simply by viewing the text in the Recognized Text Pane and ensuring it is complete. WARNING You must use voice commands to edit text. If you manually edit or delete words (by using the delete key, or selecting words and pasting or typing), these words will be deleted from the voice file. To ensure that the voice file remains intact, use voice commands (such as 'Select' or 'Scratch That') to edit the text. Voice Commands To use a voice command, simply combine an action with any one of the associated command words from the list below. The action word (or words) are always spoken first, followed by the command. For example, to bold the selected word, you could say "Bold The Selection" ('Bold' being the action and 'The Selection' being the command). Note that you must use the same language version of Dragon and Winscribe Author for the voice commands to work. For example, if you are running a German version of Dragon, you must also run Winscribe Author in German and use German voice commands. A list of Dragon voice commands is supplied with your Dragon speech recognition software, however not all of Dragon's formatting commands are compatible with Winscribe Author. Following is a list of voice commands that can be used with Author.

Hardware Considerations When deciding on the number and configuration of computers for the installation, take into account the following considerations: In large installations, you should not run the Speech Recognition Engine and Winscribe Speech Recognition Controller on the same server. 43

44 Winscribe Dragon Speech Recognition Guide When distributing Dragon components across several servers, the Winscribe Speech Recognition Adaptor and the Winscribe Speech Recognition Controller must be registered on the same domain. Workgroup membership is not sufficient. Intensive Reporting should not be run against any production database during working hours as performance will be impacted. Since speech recognition is an intensive task, no other tasks or system services should be run on the same server. System Requirements for Dragon NaturallySpeaking Please refer to the Nuance website ( for a list of system requirements that must be met in order to install Dragon NaturallySpeaking. Note: Speech recognition is a processor-intensive task, and the system requirements given by Nuance are the absolute minimum requirements for a speech recognition server. Network Requirements Please note that the Winscribe Dictation server and the Winscribe Speech Recognition Controller require local area network connectivity in order to operate correctly. A network with a transfer rate of at least 100 Mbit/s is strongly recommended. TCP/IP protocol is required on all workstations and servers running Winscribe applications or services. Servers are uniquely identifiable via DNS. The PCs hosting the Speech Recognition components must all reside on the same Windows domain. However, if required, the Dictation Server and the Submitter can reside together on a separate domain as they can communicate via the HTTP protocol. Overview of Installation Steps The following table gives an overview of the steps detailed in this installation section. Important: To determine which steps are required for your installation, follow the steps given in the following sections: Single Machine Installation (see page 45) Small Installation (see page 46) Medium/Large Installation (see page 48) Before you begin the Installation Determine your speech recognition hardware and software requirements, using the previous section as a guide.

You'll need a speech recognition license for each author that is going to submit jobs for Speech Recognition. 54

55 Installing Winscribe Server Speech Recognition A speech recognition license is assigned to an author the very first time that an author's job is submitted to the Winscribe Speech Recognition Controller, either as a newly dictated job via Internet Author or Winscribe Author, or as part of initial training via the Training Application. For example, let's imagine that your Winscribe Speech Recognition Controller had 10 speech recognition licenses. You'll then need to use the Training Application to train your authors. As you submit files for your authors, the Winscribe Speech Recognition Controller assigns a speech recognition license to each author up until the 10th author. Note: Authors can dictate in multiple contexts without requiring separate speech recognition licenses. Each author requires a single speech recognition license, regardless of the number of contexts used. The only restriction is that an author can only use a single language. Adding Speech Recognition Licenses To use Speech Recognition, you need to add speech recognition licenses. This is done through the Winscribe License Server. To add licenses to the Winscribe License Server: 1. Open a web browser and go to the Winscribe License Server: LicenseServer Servername is the name of the server on which the License Server is installed. LicenseServer is the virtual directory name entered when installing the License Server. 2. Select the Manage Licenses menu item at the top of the page. 3. If prompted, enter the administrator username and password then click Login. Both the user name and password are defined during the License Server installation process. 4. Copy the Installation ID and submit it to Winscribe with the following additional details: Customer name Winscribe Reseller name License quantity Submit these details by to Winscribe Technical Support (mailto:helpdesk@winscribe.com). 55

You should also have the latest Microsoft service packs installed. 66

67 Installing Winscribe Server Speech Recognition Considerations for Installing Winscribe Web Components Winscribe client technology uses the HTTP(S) internet protocol to communicate with the Winscribe Server. The client applications require the Winscribe Web Components to operate on a designated web server. The considerations for these client applications are: the ability to communicate with the server using the HTTP or HTTPS protocol over TCP/IP. they work in a LAN/WAN environment and over the Internet. they require IIS on the Server and Internet Explorer 6.0 or higher on the Client PC to operate. they can use password authentication, encryption, and Certificates to secure access to dictation. they allow users to work off-line (i.e. without a connection to the Winscribe Server) the Internet Clients require less bandwidth to operate, and provide a higher level of security. When installing the Internet Clients, the Web Components need to be installed on a computer running IIS (Microsoft Internet Information Server) version 5.0 or above. IIS can be installed on the Winscribe Primary Server, but if the Server has a connection to the Internet, it is preferable to have IIS on a separate machine, or at least have the Winscribe Web Components working directory on a different partition to the operating system. If you already have an IIS Server, then the Winscribe Web Components can reside on that machine. Installing the Web Components Note: The instructions below detail the installation of the Winscribe Data Provider. The installer used (Winscribe Web Components) additionally enables installation of the Web Manager and the Mobile Web Service. If you would like to install all three web components at the same time, follow the instructions in Appendix 3. Installing the Web Components (Full). Prerequisite Requirement: The Data Provider requires.net 4 to be installed. To install the Winscribe Web Components: 1. From the Winscribe Dictation 4.2 Installer DVD web page, select: Server / Winscribe Web Components 67

68 Winscribe Dragon Speech Recognition Guide Or run the supplied WinscribeWebComponents.msi: Note: By default, web components are installed under: C:\Program Files(x86)\Winscribe\Web Components\ 2. Click Accept and Install to continue: 3. Select to install Data Provider, and then click Next: 68

69 Installing Winscribe Server Speech Recognition 4. Enter the Database connection credentials: Enter your database Username and Password, and select the Connection type. Click Next. 5. Click Install to install the Data Provider: 6. The installation is now complete. Click Finish to complete and exit the setup wizard: IIS6 comes with a limit on the size of files that are allowed to be transferred via ASP scripts. This limit blocks large Winscribe jobs from being downloaded. You can increase this limit by following the instructions in Increasing IIS File-size Limit. 69

70 Winscribe Dragon Speech Recognition Guide Note: You must ensure that the Winscribe Web Components will have full access to the Winscribe Shared Directory. The Web Components 'impersonate' a user when they try to gain access to the Shared Directory, so the user account that the components impersonate must have full access to the shared directory. The impersonated user is determined by the Identity of the Application Pool associated with Winscribe site in IIS (DictationAppPool by default). If you use other security methods, you will need to ensure all appropriate users have access to the shared directory. Step 10 Install SQL Express This step is only required if the Database will not reside on the same server as the Winscribe Speech Recognition Controller. That is, for large or medium installations, where the SQL Server Software is installed on a separate server to the Winscribe Speech Recognition Controller. Note: SQL Express is required to be installed on the Winscribe Speech Recognition Controller server if no other database is present on that server, purely for the installation process. If during the installation of the Controller you point to a separate SQL Server database, SQL Express can then be uninstalled if required. We recommend, however, that you simply stop the SQL Express service rather than uninstalling it, as SQL Express will be required for future service pack upgrades. SQL Express can be downloaded from the Microsoft website. Step 11 Install Winscribe Speech Recognition Controller The Winscribe Speech Recognition Controller manages the connection of one or more Winscribe Dictation Systems to one or more Speech Recognition Engines. Speech Recognition Purge and Adaptation Service The Speech Recognition Purge and Adaptation Service is also installed as part of the Winscribe Speech Recognition Controller installation. The Adaptation Service regularly cycles through the set of speech recognition users and sends at least 5 minutes worth of historic audio and corrected text to the speech recognition engine for re-training purposes. The Purge service runs regularly to purge from the database, audio and text that has been completed by the Adaptation Service. Prerequisites Web Services Enhancements (WSE) 2.0 must be installed on the Controller server before proceeding. The installation of SQL for use by the Winscribe Speech Recognition Controller must include SQL account credentials for use by the Controller, as detailed in Step 6 (see page 52). Microsoft.NET 4 must be installed on the server, as detailed in Step 1 Install.NET (see page 49) Note that other versions of Microsoft.NET Runtime may be installed alongside, but will not be used by Winscribe. 70

78 Winscribe Dragon Speech Recognition Guide 4. You are now ready to install. Click Install to proceed: 5. When the installation has been completed, click Finish to exit the Setup Wizard: Step 16 Schedule Acoustic Adaptation and Purging Acoustic Adaptation Winscribe SR Controller uses an Adaptation Service to automatically submit corrected jobs to the relevant speech recognition engine for acoustic adaptation. This service submits the most recent job(s) from each author, provided that at least 5 minutes of dictation are available. If the most recent job of an author is over 5 minutes of dictation, then only this job will be submitted. If the most recent job is less than 5 minutes of dictation, the service will look for other jobs to reach a compound dictation time of at least 5 minutes. If an author has less than 5 minutes of dictation across all the jobs, then no acoustic adaptation occurs. Purging Winscribe SR Controller has a Purge Service that removes all the stored data and files for completed jobs. When scheduling the purging, special care must be taken not to remove data before it is submitted for adaptation. As an example, adaptation could be scheduled to run every Sunday in the morning, and purging every Sunday night. 78

79 Installing Winscribe Server Speech Recognition We recommend you set the purge to run at least four hours after the adaptation service starts. However, jobs dictated during the period between the time the adaptation service finishes and the purge service starts will not be sent for adaptation, but will be included in the purge. Therefore, it is best to set both the adaptation and the purge at quiet times when dictations are not generally submitted. Scheduling Acoustic Adaptation You can configure on which days of the week the automated adaptation will occur and at what time. To schedule acoustic adaptation: 1. On the Speech Recognition Controller Server, open a web browser and go to: 2. Select the Schedule menu item at top of the page. 3. In the Adaptation section: Select the day(s) of the week when acoustic adaptation must occur. Define the time when acoustic adaptation must occur. Save the changes. Notes: The time is entered using one of the following formats: 12 hour format, e.g. 01:30 p.m. 79

80 Winscribe Dragon Speech Recognition Guide 24 hour format, e.g. 13:30 Saving the changes automatically restarts the Adaptation Service. Scheduling Purging You can configure on which weekdays the automated purging will occur and at what time. We recommend you set the purge to run at least four hours after the adaptation service starts. However, jobs dictated during the period between the time the adaptation service finishes and the purge service starts will not be sent for adaptation, but will be included in the purge. Therefore, it is best to set both the adaptation and the purge at quiet times when dictations are not generally submitted. To schedule purging: 1. On the Speech Recognition Controller Server, open a web browser and go to: 2. Select the Schedule menu item at the top of the page. 3. In the Purge section: Notes: Select the day(s) of the week when purging will occur. Define the time when purging will occur. Note that purging should be set to occur after the adaptation process. We recommend you leave at least four hours between these two processes. Save the changes. 80

81 Installing Winscribe Server Speech Recognition The time is entered using one of the following formats: 12 hour format, e.g. 01:30 p.m. 24 hour format, e.g. 13:30 Saving the changes automatically restarts the Purge Service. Step 17 Set Server Speech Recognition Volume Control For accurate speech recognition, it is important that the volume levels are set correctly when authors record their dictation. With client speech recognition, authors go through a hardware adaptation process that optimizes the recording volume of the device being used. Therefore, with client speech recognition, the audio received by the transcriptionist is at speech recognition adjusted levels. However, with server speech recognition, the speech recognition software is not installed locally, and therefore the hardware adaptation process is not run on the author's PC. To ensure that server speech recognition is not compromised by audio that is too loud, each author must manage their own volume levels and complete a testing process to find their optimum recording volume. Setting the Correct Volume 1. Open the Options window. 2. Move the Microphone slider to the left to turn the microphone recording volume down. Move the Volume slider to the right to turn the playback volume up. Click OK to close the window. 3. Test the new settings by starting a job and recording some audio, then playing it back. Listen to ensure that the speech is coming through clearly and there is no background noise picked up by the microphone. If the recording volume is too loud, crackling or humming will generally be audible. 81

82 Winscribe Dragon Speech Recognition Guide Note: Winscribe recommends that you lower the microphone volume to a minimum level where the volume meter in Winscribe Author is just in the green (i.e. 1 green bar). This will require you to turn up the playback volume to hear the audio at the correct level during playback. This setting should result in an improved recognition rate for server speech recognition processing and an improvement in playback levels for transcriptionists. 82

If the 'Contexts Updated Successfully' message DOES exist for the Submitter and the Adapter, but the Contexts are still unavailable for selection for a Job Type, log out of the Web Manager and close your browser window, and then log back into it and check again. The Winscribe SR Adaptor Service is not starting (Error messages are displayed when attempting to start the Winscribe SR Adaptor Service) Follow these steps to start the Winscribe SR Adaptor Service: 1. Check the User Profiles Location on the Configuration page of the Winscribe Speech Recognition web application. If the Winscribe SR Controller service and the Winscribe SR Adapter service are installed on the same machine then the path should specify a local file system path. Otherwise you should use a UNC path. 2. Perform an IIS Reset. 3. Restart the Winscribe SR Adapter. 4. If the SR Adapter still does not start, provide administrator credentials as follows: a. Right click on My Computer (this could be on your desktop or your Start Menu) and choose Manage. b. This opens the Computer Management window. c. From the left hand tree view pane, select Services and Applications, and then Services. d. Scroll down on the right hand pane, until you find the Winscribe Speech Recognition Adapter Service. Right click, and select Properties. e. Select the Logon tab. Select the 'This Account' radio button, and enter administrator credentials (User ID and Password). Machine is not connected to Network, a UNC (Universal Naming Convention) cannot be resolved. If Winscribe is being installed onto a single machine (for example, for demonstration purposes), the full directory path must be entered into the Configuration settings. This is because when the machine is disconnected from the network, the machine name will not be able to be resolved. 94

95 Troubleshooting Speech Recognition Installation Solution: In the Winscribe Speech Recognition Controller, select Configuration from the menu. In the User Profiles section, check the Location field. It may be showing just the machine name, for example: \\<machine name>\speakerprofiles. Change this by typing the full directory path into this field (for example: c:\program files\...\speakerprofiles). Object Reference not set to an instance of an object This message may be displayed by Winscribe Web Manager after you add a Speaker Profile path in the Winscribe Web Server settings. Solution: Perform the following steps (from Winscribe KnowledgeBase 630): 1. Click Start, and then click Run. 2. Type regsvr32 <Windows folder>\microsoft.net\framework\<version Number>\aspnet_isapi.dll, and then click OK. Regsvr32 returns the results of the registration. 95

96 Winscribe Dragon Speech Recognition Guide Setting Up Server Speech Recognition for Job Types, Authors and Typists When setting up your server speech recognition, you should determine which authors will be using it speech recognition for what type of jobs, and set up your job types and author settings accordingly. This section details the requirements for job types and authors, and also covers switching on synchronization for typists. Job Types Job Types are used to categorize the type of work being dictated. handled by speech recognition. They also determine how jobs are Server Speech Recognition If you are running server speech recognition, you need to 'turn on' speech recognition and select a speech recognition topic for any job types that require speech recognition processing. Follow the Switching On Speech Recognition For Job Types procedure (below) to turn on speech recognition for all job types that require it. All jobs with job types that have speech recognition switched on will be sent to the server for speech recognition processing; if the Author that creates the job has Speech Recognition enabled on their profile. Client Speech Recognition Any job can be processed using speech recognition if the Author has client speech recognition installed, and turns on speech recognition for that job before commencing dictation. If a job type has not had speech recognition switched on, the author will need to click Speech Recognition on the new job form menu in Winscribe Author for every new dictation. For Speech Recognition to be enabled automatically, enable Speech Recognition for the job type. Sites Running Both Client and Server Speech Recognition If you are running both client and server speech recognition, the following rules apply: Speech recognition can be processed on any job locally using client speech recognition. If a job uses a job type that has speech recognition switched on, Winscribe will check whether speech recognition has been processed locally. If it has already been processed, no further action is taken. If not, the job will be sent to the server for processing. Switching on Speech Recognition for Job Types Use the following procedure to switch on speech recognition for all job types that require it. 1. Login to Winscribe Web Manager. 2. From the menu, select Groups, then Job Types, and then Update. A list of job types will be displayed. Click on the one you wish to update to display the Update Job Type window. 96

97 Setting Up Server Speech Recognition for Job Types, Authors and 3. In the Miscellaneous section, select the Speech Recognition checkbox. Note: A Speech Recognition Topic will need to be selected on the Department Job Types page. 4. Click Update Type to save the change. Switching on Server Speech Recognition for Authors For server speech recognition to be processed for an author, that author profile must first be flagged for speech recognition. Note that this setting is only required for authors using server speech recognition. able to use client speech recognition if they have Dragon installed locally. 1. Log in to Winscribe Web Manager. All authors will be 2. Select Users / Authors / Update. Click on the required author to access the Update Author window. 3. Enable the Send jobs for Speech Recognition checkbox. This will mean that jobs dictated by this author will be forwarded to the speech recognition server for processing. Note: The Job Type that the author dictates must also be selected for speech recognition otherwise this setting will be ignored. 97

98 Winscribe Dragon Speech Recognition Guide 4. Select the appropriate language for the author from the list of Base Languages in the drop-down menu. Note: If a Base Language has not been selected here, the user will be prompted to select a Base Language before starting dictation. 5. Enable the Send jobs for Acoustic Adaptation checkbox. This will mean that jobs that have been proofread and corrected by a typist (completed after the speech recognition process) will be submitted back to the SR server for acoustic adaptation provided the adaptation service schedule has been configured. Important: Once no further improvement can be seen in the recognition rate for that author, it is important that the author profile is updated and the option to send jobs for acoustic adaptation is disabled. If this setting is left on, the quality of the adaptation can deteriorate and lead to performance issues. 98

105 Configuring Server Speech Recognition Note: If multiple services are installed on the same server, selecting a service name loads the messages for that service without prompting for username and password. If attempting to view an Adapter that resides on another server you will be prompted for domain credentials. To suppress this prompt every time, you can set the Controller to impersonate a valid user. To impersonate a domain user add the line <identity impersonate="true" username="username@domain" password="password" /> to the web.config file under the <System.web> node. The web.config file can be found under C:\Program Files\Winscribe\Winscribe SR Controller\SpeechRecognitionService\ Speech Recognition License Management Winscribe Speech Recognition reserves a Speech Recognition License for every user that submits speech recognition jobs. Both 'license reservation' and 'user profile creation' occurs at the same time the first time that an author submits a speech recognition job. When authors no longer need to submit speech recognition jobs, their speech recognition licenses can be released and made available to other authors. For details on adding licenses, see Step 8 Add Speech Recognition Licenses (see page 54). For further information on licenses and the Winscribe License Server, refer to the Winscribe License Server Installation and User Guide. Releasing Speech Recognition Licenses To release speech recognition licenses of authors who no longer require speech recognition, use the Release Licenses window in the Winscribe License Server, as detailed in the Winscribe License Server Installation and User Guide. Allocating Speech Recognition Licenses Speech recognition licenses can be allocated to a specific system. This is useful in cases where the Winscribe Speech Recognition Controller is hosted by an Application Service Provider (ASP). The ASP purchases the speech recognition license(s) from Winscribe Inc and then on-sells them as a service to various organizations. Each organization uses a Winscribe dictation system to consume the speech recognition services offered by the ASP. Each of these Winscribe dictation systems requires a unique identifier, called the system name, which will be agreed upon between the ASP and the organization consuming their speech recognition service. The ASP will usually allocate a number of speech recognition licenses to each organization in order to ensure that: When an organization purchases a number of speech recognition licenses, these licenses are reserved for that organization. An organization cannot exceed the number of licenses purchased. Unallocated speech recognition licenses form a general license pool and are available to any organization. When an author requires a speech recognition license, the License Server will first look for an available license in the number of licenses allocated to the system the author belongs to. If all the licenses allocated to the author's system are in use, or if no licenses have been allocated the author's system, the License Server will look for an available license in the general license pool. Speech Recognition licenses are allocated using the Winscribe License Server. Refer to the Winscribe License Server Installation and User Guide for details on how to allocate licenses. 105

106 Winscribe Dragon Speech Recognition Guide Server Speech Recognition Training The Winscribe Speech Recognition Training application enables you to run acoustic and context adaptation for authors, in order to improve their recognition rate. Acoustic Adaptation When acoustic adaptation is run on a text-audio pair, the speech recognition engine learns how the author speaks and adapts the acoustic reference files for the author to further enhance the recognition rate. During acoustic adaptation, the speech recognition engine analyses the submitted sound file as well as the corrected text and updates the acoustic reference in the author's profile. Context Adaptation When context adaptation is run on text that has been corrected by the typist, the speech recognition engine uses the statistical data in the current vocabulary to predict the word that most likely matches what the author actually said. For example, the language model favors the word pair "world affairs" over "whirled affairs," because "world" occurs more frequently than "whirled" and because "world affairs" occurs more frequently than "whirled affairs" in the speech and writing of target users. Notice that the two-word sequences sound exactly alike, so the acoustic model can do nothing to differentiate them. The language model calculation is the only information that can help make the right choice. During context adaptation, the speech recognition engine analyses the submitted corrected texts and updates the statistical data in the author's vocabulary. Running Acoustic Adaptation For each author, you need to: Collect at least 10 minutes of dictation and related corrected text. For practical use, it is recommended to use 1 hour of dictation for initial training. Know the speech recognition context to be associated with the files. 1. Start the Winscribe Speech Recognition Training application. 2. Select the Facility of the author to be trained. 3. Select the Author Name of the author to be trained. 106

107 Server Speech Recognition Training 4. Select the Context to be used for training. 5. Select Acoustic adaptation as initial training. 6. Use the Add Audio button to browse to a dictation file and add it to the list of audio files. Use the Add Text button to browse to the corrected text file that contains the text related to the just added audio file, and add it to the list of text files. If you add a file by mistake, select it and then use the Remove button to remove it from the list. The pairs of audio/text files are matched by the order in which they appear in the lists, i.e. the first audio file is matched with the first text file, and so on. 107

108 Winscribe Dragon Speech Recognition Guide 7. Select the Submit Files for adaptation button to submit the files for acoustic adaptation. 8. When prompted for confirmation, select OK. 9. The Status area shows the results of the acoustic adaptation. Groups of files that were successfully submitted for acoustic adaptation will appear in the status area with a Task ID number. The Task Status column in the Status area shows the phase of the acoustic adaptation, and is one of the following: Waiting to be processed Processing Completed Failed The Failure Reason column in the Status area is only defined for failed tasks. In order to read the full reason, the height and/or width of this column might need to be increased. 108

109 Server Speech Recognition Training The Status area can be refreshed either by pressing F5 on the keyboard or by selecting View Refresh from the menu. Notes Audio files must be in one of the following formats: VOX, WAV, WMA, AVI, MP3, MP2, G721, G723, or G726. When using WAV ensure the format is 22KHz, 16 bit mono. All the audio files submitted for acoustic adaptation must be in the same format. This is enforced by the application. Winscribe Dictation Server stores the audio files in the \Winscribe\Server\Recrding folder. Text files must be in one of the following formats: TXT or RTF. All the text files submitted for acoustic adaptation must be in the same format. This is enforced by the application. Text files must contain at least 25 words in order to be valid for acoustic adaptation. If audio files and text files are stored in the same folder and use the same file names, adding an audio file to the audio files list will automatically add the matching text file to the text files list. Precaution must be taken not to apply the wrong files or context, as submission of files for acoustic adaptation is final and can't be undone. At this stage, it is not possible to find out when an author has been sufficiently trained. This feature might be included in a future release of the Winscribe speech recognition Training application. Acoustic adaptation does not include context adaptation, i.e. the text files submitted for acoustic adaptation are not used for context adaptation. By default, the Winscribe Speech Recognition Training application keeps the history of all submitted acoustic adaptation tasks, and shows this in the Status area. The application can be configured to only keep the pending tasks, i.e. where the status is either Waiting to be processed or Processing. To do this, either press F4 on the keyboard or select Tools Options from the menu. Select Delete history on status refresh and press Save. Running Context Adaptation For each author, you need to: Collect at least 10 minutes of corrected text. For practical use, it is recommended to use 1 hour of dictation for initial training. Know the speech recognition context to be associated with the files. 1. Start the Winscribe Speech Recognition Training application. 109

113 Working with Vocabularies (Contexts) Working with Vocabularies (Contexts) When setting up Winscribe Server Speech Recognition, it can be helpful to plan your vocabulary requirements in advance in order to minimize the work required. If there are custom words that will be required by all staff, these can be added to your base vocabulary. Once all the required words have been added to the base vocabulary, the base vocabulary can be copied and renamed for groups or individuals that have their own vocabulary requirement. Their additional custom words can then be added to their own custom vocabularies. Creating Custom Vocabularies Use the following procedure to add words to the main vocabulary, then copy and rename that base vocabulary to create a new custom vocabulary. This procedure is in two steps. Step one guides you through the process of adding words to the base vocabulary. Step two details the creation of the new custom vocabulary. Step One: Add words to the Base Vocabulary. 1. Ensure that server speech recognition is installed and operating. Give the Winscribe user speech recognition rights. 2. Using Web Manager, open the Update Job Type window and select the required speech recognition context for the required Job Type. (Refer to Switching on Speech Recognition for Job Types (see page 96) for full details on how to do this). 3. Do a single dictation. (This is just to make the user accessible to Voctool). Close the Winscribe application. 4. Stop all Winscribe Services, as follows: Open your web browser and point it to the Winscribe Speech Recognition User Interface ( ( Select the Service option from the Diagnostics menu item at the top of the page. Stop the Adapter Service from running by clicking on the Stop icon. Under Service Name, click on the down arrow to select the Submitter Service and then stop that from running by clicking on the Stop icon. Under Service Name, select Purge Adaptation Service and then stop that from running also. Close the Browser Window. 5. Run the following application: C:\Program Files\Nuance\NaturallySpeaking9\Program\voctool.exe 6. Select the user and vocabulary and click OK. 113

114 Winscribe Dragon Speech Recognition Guide 7. Select 'Add new words from documents and adapt to writing style'. Click Next to continue. 8. Add documents to be reviewed by clicking on the Add Folder or Add Document buttons. Once you have selected the required documents, click Next to continue. 9. Select 'Find unknown words'. This will locate words that are not in the current vocabulary. If required, you can also select 'Find known words with unknown capitalization'. This will add words that are already in the dictionary with a different capitalization. It is also advisable to select 'Preview the list of unknown words'. This enables you to edit or omit words in case of any spelling mistakes. 114

115 Working with Vocabularies (Contexts) Click Next to continue. 10. As each document is analyzed, it is ticked off. Once all documents have been analyzed, click Next to continue. 11. If you selected to preview the list of unknown words, they will now be displayed. Untick any words that you do not wish to be added to the base vocabulary. Also ensure that all words being added are spelled correctly before continuing. If you wish to train added words, leave the 'Train added words' checkbox ticked. Note that this option enables you to teach Dragon how the words sound, but the training will be done in your voice. 115

116 Winscribe Dragon Speech Recognition Guide Click Next to continue. 12. If you have selected to train words, you will now need to select the words to train. When you click Next, you will be prompted to speak each word one by one, and Dragon will learn how the words are pronounced. 13. When asked which slot to modify, you must select 'Middle Slot'. This will ensure the new dictionary is propagated to all users when created. Note: If the 'User Slot' is selected, only the particular user selected within Voctool will have their dictionary updated. 116

117 Working with Vocabularies (Contexts) Click Next to continue. 14. Click Finish to close the Vocabulary Tool and return to the windows desktop. Step Two: Copy the Base Vocabulary and Create a New Vocabulary 1. Locate the Base vocabulary files, as follows: The base vocabulary files are in the following directory C:\Documents and Settings\All Users\Application Data\Nuance\NaturallySpeaking9\Data\ Which subdirectory they are in depends on the base topic you selected for the user. If you selected an Australian topic, the vocabulary files will be in the 'aus' subdirectory. If you selected an American English topic, the vocabulary files will be in the 'eng' subdirectory. UK English files will be in the 'enx' subdirectory. There are 7 files in total: all.bd, general.svc, token.enh, dd10voc1.voc, dd10voc2.voc, dd10voc3.voc, general.voc 2. Copy the Base vocabulary files to a separate location on the hard disk, for example, into c:\temp. Note: When naming the directory in which you will temporarily store your vocabulary files, it is best to keep the name simple as long folder names are not accepted. 3. Open a command prompt by selecting Run from the Start menu, and typing in 'cmd'. 117

118 Winscribe Dragon Speech Recognition Guide Note: All Winscribe services should still be stopped (as detailed in step one). 4. Type in 'cd C:\Program Files\Nuance\NaturallySpeaking9\Program' to change the working directory to that directory. 5. Type in: nsadmin /vocabulary <path to base vocabulary> "<vocabulary name>" 9002 Note the following: Replace <path to base vocabulary> with the temporary directory you specified in step 2. the <> symbols. Replace <vocabulary name> with the name you want the new vocabulary to have. Omit the <> symbols. The number at the end (in this case 9002) must be a unique number, and must be above It is used to reference the folder where the new vocabulary is stored. Note that if this is not a new installation it is advisable to check the location of custom vocabularies and make a note of the last custom folder number. An example command is as follows: Nsadmin /vocabulary c:\temp "Australian English Large Winscribe" If the process was successful, a message will be displayed in the command window. Omit A new folder (in this case Custom9002) will be automatically created in the same location as the base directory files. 7. Restart all Winscribe Services. The new context is now ready to be used and can be selected from the drop down menu when creating or editing job types. Adding Base Vocabularies using the Data Distribution Tool You can add new base vocabularies using the Dragon NaturallySpeaking Data Distribution Tool. If using both client and server speech recognition, you must carry out this procedure on both the server and the client machines. Use the following procedure to add base vocabularies: 118

119 Working with Vocabularies (Contexts) 1. From the Start Menu, select All Programs, then the Dragon Naturally Speaking folder, Dragon Naturally Speaking Tools, then click on the Data Distribution Tool. This opens the Dragon NaturallySpeaking Data Distribution Tool window, as shown below. 2. Select to Add or Remove base vocabularies and click on the Next button to continue. 3.

124 Winscribe Dragon Speech Recognition Guide Troubleshooting Speech Recognition Operation This section provides information on troubleshooting the operation of both client and server speech recognition. For troubleshooting during installation of server speech recognition, see Troubleshooting Speech Recognition Installation (see page 86). For troubleshooting global commands see Troubleshooting Global Commands. Problems and Solutions Problem When attempting to use client speech recognition, Dragon NaturallySpeaking does not start. Server speech recognition processing does not run. A lined page icon indicates speech recognition processing has been successfully completed and the job is ready for transcription. However, if after several minutes (and after the screen is refreshed), the page icon next to your job remains blank or disappears entirely, this indicates there is a problem with your speech recognition setup. When starting a job using client speech recognition, Winscribe cannot load or find the vocabulary. The first time a client speech recognition job is started, runtime error 3265 is displayed. The sound is jerky when a typist replays a job if the playback speed has been changed. When creating server speech recognition jobs, speaker profiles are not created. Solution Check if Dragon NaturallySpeaking has been installed on the local machine. In the Winscribe Author, select Options from the Tools menu and click on the Speech Recognition tab. Check that client speech recognition has been enabled (Dragon has been selected) on this tab. Check that all Winscribe services have started on the server(s), by opening the web browser on the Speech Recognition Controller server, and directing the browser to: x Click on Diagnostics on the menu, and check that for each service, the Status is Running and not Stopped. Also check any error messages that may be displayed. If all services are running and speech recognition is still not processing, complete all procedures detailed in the Validating the Operation of Speech Recognition section of this guide. Adapted vocabularies which have been assigned to job types in Winscribe must also be added to the Author's local machine. Refer to the Adding Base Vocabularies using the Data Distribution Tool section of this guide for more details. This error arises if Winscribe Author is offline. Ensure Winscribe Author is online and start the job again. Upgrade to the latest version of Winscribe. Use the following steps to solve this: Check whether Dragon NaturallySpeaking generates a Runtime error on the speech server by starting the programme (manually). If it does, close Dragon NaturallySpeaking. Check in Task Manager that Dragon NaturallySpeaking is no longer running. Stop the Winscribe Speech Recognition Adapter service. Start Dragon NaturallySpeaking again on the speech server and check if the path to the Speakerprofiles share has been set up properly. 124

125 Troubleshooting Speech Recognition Operation Problem Solution Close Dragon NaturallySpeaking. Start the Winscribe Speech Recognition Adapter service. Empty the local profiles map (cache) on the speech server: C/Document and Setting/All Users/Application Data/Nuance/NaturallySpeaking/Users/Winscribe. Frequently Asked Questions I have manually deleted the speaker profile. Is there anything else I must do? You must delete the cache copy of the profile as well, particularly if you are replacing the profile with an earlier version. In some cases you may wish to release the speaker license through the Winscribe Speech Recognition Controller user interface. I receive an error that the Adapter cannot convert the audio file to WAV. What can I do? The NCT COM audio libraries are missing or not registered: NCTAudioCompress2.dll NCTAudioFile2.dll NCTWMAFile2.dll Starting the Adapter results in an error with GetSpeakerProfiles(). The error may include "The request failed with HTTP status 405: Method not allowed". What can I do? Browse to the Winscribe Speech Recognition Controller configuration page. Check and Re-save the speaker profile path. Client side speech recognition gives very good results, however, server side recognition is not as accurate, why? The audio sent to the Dragon Engine in client side is raw PCM, where the PC has had acoustic tuning performed by Dragon. The audio sent to the server side is converted to a lower quality compressed format (GSM 22kHz, 16 bit mono) and processed by the Dragon as an audio file input, without acoustic tuning. Recognition will drop because the compressed GSM audio does not have the same acoustic model as the PCM equivalent, which was used to train the profile. How does Acoustic Adaptation work? The Adaptation and Purge Service submits the most recent job(s) from each author, provided that at least 5 minutes of dictation are available. If the most recent job of an author is over 5 minutes of dictation, then only this job will be submitted. If the most recent job is less than 5 minutes of dictation, the service will look for other jobs to reach a compound dictation time of at least 5 minutes. If an author has less than 5 minutes of dictation across all the jobs, then no acoustic adaptation occurs. The following diagram shows that: Context Adaptation happens straight away after the typist has completed the correction. 125

126 Winscribe Dragon Speech Recognition Guide Acoustic adaptation happens at regular intervals, i.e. according to the adaptation schedule. Choosing text correction from the Typist application does not significantly improve the recognition rate. Why? Typist text correction is not acoustic adaptation, although the corrected text is used later by the Acoustic adaptation service. If the recognizer gets the word "spell" wrong, correcting it will make no difference because "spell" is already in the Vocabulary. It's the acoustic model of the word versus the users profile that is incorrect. The user needs to do more audio training. It is also possible to use the NSAdmin tool that is supplied with the Dragon software to edit the profile and vocabulary/topics. Dragon runs at 100% CPU. Why? The Dragon engine uses as much CPU as it can to perform its tasks. On occasion it never completes the assigned task and will enter a race condition. This is a fault in the Dragon engine that requires the Adapter service to be stopped and the NatSpeak.exe process killed. The Adapter service can then be restarted. The server reports a Dragon dialog box with a catastrophic failure of the application. What should I do? The fault is in the Dragon code firstly generating the error and secondly displaying a dialog box instead of returning an error code through the API. Please restart the server and Adapter service. If the error persists please contact the Winscribe Helpdesk. The issue requires an update to Natspeak.exe and dd10shrd.dll in the DNS product. These replacement files are available from Winscribe Support. 126

127 Glossary of Terms When I change the time on the Adaptation or Purge Service and save, nothing appears to happen. The Purge and Adaptation Service runs once per day at the time set. If the service has already run, changing the time will not take effect until the next active day. To force the process to run, delete the log.xml file from the purgeandadaptation service installed directory. (Example: C:\Program Files\Winscribe\Winscribe SR Controller\PurgeAdaptationService\Log.xml) This daily reoccurrence is by design to allow enough acoustic data to be collected and to prevent the Adaptation process from consuming the Dragon engine during the time required for recognition. The Adaptation execution is reported in the event log or through the Winscribe Speech Recognition Controller web management under the Diagnostics>Services menu option. Can Profiles be used for client side and server side recognition? This is possible within limits. If the profile is created through the Winscribe Author (using client side recognition) and licensed then the Author can choose job types setup for server side recognition. Their profile will be loaded by the Server if it points to the same speaker profile share location and they have a valid license. You cannot create a profile in the Dragon application and utilize this profile for the server implementation. When I add a new facility and configure the job types for server side recognition, the jobs are not picked up by the Winscribe Speech Recognition Submitter. Glossary of Terms Please restart the Submitter service. on the new Facilities job table. This process results in the submitter installing a database trigger Speech Recognition Controller The Speech Recognition Controller manages traffic between the Winscribe Dictation System and the Speech Recognition Engine. Requests from multiple Dictation sources may be received at a faster rate than the speech recognition engine can keep up with. The speech recognition controller queues incoming requests against the associated engine asynchronously so that Dictation services may continue without waiting for completion of the speech recognition process. Dictation Dictation is carried out in Winscribe Author, Winscribe Internet Author or Winscribe Telephone Author, or imported from other systems or digital devices. Before starting dictation for speech recognition, authors carry out a simple procedure, called Initial Training, that allows the system to better recognize their individual voices. 127

128 Winscribe Dragon Speech Recognition Guide Recognition Recognition is the computerized process that converts speech to text. As an author continues to dictate, the system constantly improves the recognition of their voice and vocabulary. These ongoing processes are called Acoustic Adaptation and Language Adaptation respectively. Correction Correction is carried out using Winscribe Client. This program displays the recognized text in Microsoft Word ready for the transcriptionist to correct. As the transcriptionist plays back the recording, the words are highlighted on screen, synchronized with the author's dictation. They can then correct any words that have been wrongly recognized. Applications and Services The Winscribe Speech Recognition and Dragon applications run on a distributed network of servers. The following system services run continuously on one or more servers. System Service Winscribe SR Submitter Winscribe SR Controller Speech Recognition Server Winscribe SR Adapter Winscribe License Server Microsoft Internet Information Server Microsoft SQL Server Purpose Provides the communication between Winscribe Dictation System and the Winscribe Speech Recognition Controller. Distributes dictations to recognition servers. Manages Transcription, Adaptation, and Training. Performs Maintenance tasks such as purging. Validates Licensing against the License server. Performs speech recognition and acoustic adaptation. Automatically adapts the system to an author's voice characteristics. Updates their acoustic reference file. The Adapter Service runs on processing engines that connect to the Winscribe Controller such as the Dragon Speech Recognition Engine. Manages License allocation for Winscribe Products. The Winscribe Speech Recognition Controller exposes its services through Web Services running under Microsoft IIS. Microsoft SQL server is used as a data store by the Winscribe Speech Recognition Controller. 128

129 Glossary of Terms Dictation / Correction Workflow The following diagram illustrates the workflow of a dictation through the Winscribe system and Winscribe Speech Recognition Controller. 1. An author dictates a job of a work type requiring speech recognition. 2. The Winscribe SR Submitter submits the job for speech recognition. 3. When the recognized text is available, the Submitter makes both audio and recognized text available for correction and editing. 4. When correction is complete, the Submitter submits the corrected text for context adaptation. 5. Audio and corrected text pairs are submitted for acoustic adaptation at regular intervals. 6. Unwanted files after speech recognition are removed at regular intervals. 129
