Important remark: the files AcaTTS.dll and AcaTTS.ini are expected to be found in the Current directory of the Application using the ActiveX. This way it allows to have different set of voices and settings for different products using the same ActiveX. 2.3.Programming overview The general flow of typical application using Acapela Active Speech is as following: 1. Create an instance (aka object) of IAASpeechCtrl interface 2. Connect the TTS server (Acapela Multimedia) to be used. object.connectengine 3. Unlock the TTS engine (only needed if no computer locked licence is available) Set OEMKey property to a proper value 4. Enumerate the voices available on the TTS Server object.enumerate 5. Start a TTS channel by loading the required voice object.load 6. Perform speech operations object.speak object.resume

9 Page : 9/35 NOTE object.pause object.stop 7. Stop the current TTS channel by unloading the voice object.unload 8. Disconnect from the TTS server object.disconnectengine You must create an instance of IAASpeechCtrl interface for each TTS channel/voice you plan to use (one object per voice).

10 Page : 10/35 3. API Reference 3.1. IAASpeechCtrl interface IAASpeechCtrl is the TTS control interface that controls speech operations. To use more than one voice at a time, you needs to create one instance (aka object) of this interface. In the following, the term TTS channel refers to an instance of the interface with a loaded voice Methods ConnectEngine Connect the host application to an Acapela tts engine. HRESULT ConnectEngine(nConnectionMode, nport, SrvAddress) Return Values nconnectionmode [integer] [in] Connection mode to TTS engine server EAS_AF_LOCAL (1) means local. This is the only relevant value. local tts server (same computer as client). applies to Acapela Multimedia TTS servers nport [integer] [in] Irrelevant, should be set to 0 psrvaddress [string] [in] Irrelevant, should be set to empty string. EAS_SUCCESS in case of success or EAS_ALREADY_CONNECTED host application is already connected to a server EAS_NOT_ENOUGH_MEMORY not enough memory to perform the connection EAS_SRV_NOTRUNNING server is not running

11 Page : 11/35 DisconnectEngine, LastError DisconnectEngine Release the current connection to the server. Disconnection can t be performed if a TTS channel is still active (Unload method must be called before disconnection). HRESULT DisconnectEngine() none Return Values EAS_SUCCESS in case of success or EAS_TTSCHANNEL_STILL_ACTIVE a TTS channel is still active EAS_INVALID_HANDLE invalid dispatch handle (internal error) ConnectEngine, Load, Unload, LastError Enumerate Enumerates all available voices on the TTS server and fills in VoiceCount and voice list array Voice. HRESULT Enumerate() none Return Values EAS_SUCCESS in case of success or EAS_NOT_CONNECTED host application is not connected to a server EAS_NOT_ENOUGH_MEMORY

12 Page : 12/35 not enough memory to perform the operation EAS_SRV_NOTRUNNING server is not running EAS_INVALID_HANDLE invalid dispatch handle (internal error) EAS_NO_VOICE no voice found OEMKey,Voice,VoiceCount, IAAVoiceCtrl,LastError Once the voice enumeration is done, VoiceCount property contains the number of enumerated voices, each enumerated voice is stored in an IAAVoiceCtrl object and the whole voice list (and voice properties) can be accessed thru Voice(n) property that represents an array of IAAVoiceCtrl objects. Remark: the files AcaTTS.dll and AcaTTS.ini are expected to be found in the Current directory of the Application. This way it allows to have different set of voices for different products using the same ActiveX Load Loads a voice, start a TTS channel. HRESULT Load(bstrCmd) bstrcmd [string] [in] Null terminated string that contains the identifier of the voice to load. The voice identifier for a given voice is given by the Cmd property of the IAAVoiceCtrl object (in Voice array) corresponding to the given voice. Return Values EAS_SUCCESS in case of success or EAS_NOT_CONNECTED host application is not connected to a server

13 Page : 13/35 EAS_TTSCHANNEL_STILL_ACTIVE a TTS channel is already active (call Unload before) EAS_SRV_NOTRUNNING server is not running EAS_CONNECT_ERROR unable to connect to server EAS_CONNREJECT server rejects the connection (maximum channels number reached) EAS_VOICE_LIST_ERROR given voice doesn t match a voice enumerated by the server EAS_INVALID_HANDLE invalid server handle (internal error) EAS_VOICE_INIT_ERROR error during initialization of given voice EAS_NOT_ENOUGH_MEMORY not enough memory to perform the operation EAS_CHANNEL_LOCKED channel already used by another user Unload Remark Only one voice can be loaded at a time by an object. To use more than one voice, you should create an instance (object) of Acapela Active Speech per needed voice Unload Unload a previously loaded voice. HRESULT UnLoad() Return Values or none EAS_SUCCESS in case of success

14 Page : 14/35 EAS_NOT_CONNECTED host application is not connected to a server EAS_TTSCHANNEL_NOT_ACTIVE a TTS channel is not active EAS_SRV_NOTRUNNING server is not running EAS_INVALID_HANDLE invalid server handle (internal error) Load Speak Play the provided text on the selected output. HRESULT Speak(bstrText, long ltextid) bstrtext [string] [in] Pointer to a null terminated string that contains the text to be played. ltextid [long integer] [in] text identifier Return Values EAS_SUCCESS in case of success or EAS_TTSCHANNEL_NOT_ACTIVE a TTS channel is not active EAS_EMPTY_TEXT text is empty EAS_NOT_ENOUGH_MEMORY not enough memory to add text EAS_EXEC_STARTED_ERROR can t execute speech output (internal error) EAS_PROCESS_DATA_ERROR

15 Page : 15/35 error during text to speech processing EAS_INVALID_HANDLE invalid server handle (internal error) Stop, Pause, Resume, Output The behaviour of text played depends on the Output type chosen by host application. If Output is set audio output (i.e. output to an audio card device), the audio signal is produced by TTS server at 1x real time. If Output is set to file output or callback output, the audio signal is produced by the TTS server at N x real time according to the capability of the TTS server. Producing audio signal at N x real time means that the host application receives the audio signal in a time corresponding to the real duration of the audio signal divided by N : for ex. with a 4 x real-time tts engine, the audio signal for a text which duration is 1min is produced in 15s. Acapela Multimedia is a real-time only (1X) TTS engine, Acapela Telecom is a N x real time (Nx) TTS engine, N is equivalent to the channel number stored in the (hardware or software) protection key. TTS Events are fired (if enabled) to host application during text play. Events are sent synchronously with the audio signal play to allow word or phoneme synchronization with audio signal output Stop Stop the current text played. HRESULT Stop() none Return Values EAS_SUCCESS in case of success

16 Page : 16/35 or EAS_TTSCHANNEL_NOT_ACTIVE a TTS channel is not active EAS_INVALID_HANDLE invalid server handle (internal error) Speak, Pause, Resume Pause Pause the current text play. HRESULT Pause() none Return Values EAS_SUCCESS in case of success or EAS_TTSCHANNEL_NOT_ACTIVE a TTS channel is not active Resume, Speak, Stop Resume Resume a previously paused text played. HRESULT Resume() none Return Values

17 Page : 17/35 EAS_SUCCESS in case of success or EAS_TTSCHANNEL_NOT_ACTIVE a TTS channel is not active EAS_INVALID_HANDLE invalid server handle (internal error) EAS_CHANNEL_NOTREADY problem with the channel execution EAS_PROCESS_DATA_ERROR error during text to speech processing Pause, Speak, Pause EventMask the TTS events fired to host application during a text played. HRESULT EventMask(ulEvtMask) UlEvtMask [unsigned long integer] [in] a bit field that control enabling/disabling of TTS events; each bit correspond to a given event : bit 0 n/a bit 1 enable(1)/disable(0) word position event (event mask = EVT_WORD_POSITION) bit 2 enable(1)/disable(0) phoneme event (event mask = EVT_PHONEME) bit 3-5 n/a bit 6 enable(1)/disable(0) mouth position event (event mask = EVT_MOUTH_POS) Return values EAS_SUCCESS

18 Page : 18/35 Events,Speak Some events can t be disabled and are always fired (see Events). WordPosition, Phoneme and Mouth Position are automatically disabled when Output is set to file output GetVarAudioData,GetAudioData Get the next available audio signal data in callback output. HRESULT GetVarAudioData(vData) HRESULT GetAudioData(pData, ldatasize); Return Values vdata [variant] [in] variant type buffer that will be filled in with audio data, must have the following characteristics : type : safearray of byte (VT_ARRAY VT_UI1) safearray dim : 1 pdata [byte pointer] be safearray bounds : [0, ldatasize] [in] pointer to buffer that will be filled in with audio data : buffer must large enough to receive the data ldatasize [long integer] [in] buffer size EAS_SUCCESS in case of success or EAS_TTSCHANNEL_NOT_ACTIVE a TTS channel is not active TYPE_E_TYPEMISMATCH unexpected variant type TYPE_E_BUFFERTOOSMALL buffer size too small EAS_AUDIODATA_NOTAVAILABLE

19 Page : 19/35 no available data Output Calling this method has only a meaning when Output is set to callback output. In this case host application received an AudioData event each time an audio signal data is available. The application must then call GetAudioData or GetVarAudioData to get the next available data. The data is destroyed immediately after a call to the method, so the application must insure to copy the data before using it. for developers Applications written with programming languages that can handle memory pointers may use GetAudioData method to get access to audio buffer in control. GetVarAudioData is useful for other programming languages (like Visual Basic) that can only handle data via Automation ServerShutdown Performs a shutdown of the TTS server. HRESULT ServerShutdown(nState) nstate [integer] [in] shutdown state 2 forces server shutdown though there is still an active channel (all active TTS channels are stopped and closed) 1 requests server shutdown, the behaviour depends on the current server state : if no TTS channel is active, server shutdowns itself immediately, else server waits for all TTS channels to be closed before shutdown itself (shutdown can so be cancelled) 0 cancels shutdown request

20 Page : 20/35 Return Values EAS_SUCCESS in case of success or EAS_SRV_NOTRUNNING server is not running EAS_INVALID_HANDLE invalid server handle (internal error) DisconnectEngine After calling this method, you must call DisconnectEngine to release the connection to the server Properties Voice(n) Access to a given enumerated voice list array.

[read/write] short integer low byte contains the output type : AUDIO_OUTPUT 0 FILE_OUTPUT 1 CALLBACK_OUTPUT 2 high byte contains when low byte is set to FILE_OUTPUT, the format of output file : PCM_FORMAT 0

22 Page : 22/35 WAV_FORMAT 1 Filename, Speak, Constants,GetVarAudioData,GetAudioData,Events The format of the audio signal produced by TTS server is : PCM 16bits and frequency depending on the selected voice. In audio output mode, the audio signal produced by the TTS server is played by the control on the audio device (sound card) at 1 x realtime. In file output mode, the audio signal produced by the TTS server is written by the control in the file which name is set by Filename property at N x realtime (see Speak): the format of output file is set by high byte of the property value. In callback output mode, the audio signal produced by the TTS server is sent back to the host application to allow application to handle itself the audio signal: each time a data (audio signal chunk) is available, control fires an AudioData event to the host application that must call GetVarAudioData or GetAudioData to get the data. According to the selected output mode and the event mask (see EventMask), Events are fired to the host application to allow it to perform text synchronization with audio signal play Filename Description Name of output file in file output mode. Type [read/write] null terminated string Output, Speak By default, at initialization the filename is set to AcapelaTTS.wav.
