3 WE RE HIRING! PAUL OLIVER PRINCIPAL SOFTWARE ARCHITECT

4 THE PLAN How Alexa Works Create an interactive service with slots Summary

5 ALEXA SKILL A capability for your Alexa device Custom Skills Look up info from a web service Integrate with Uber, Domino s Pizza Interactive Games Smart Home Skills Turn your lights off Change your thermostat

6 SKILL Skill Service Service Container Skill Interface Voice User Interface Configuration UTTERANCES SLOT TYPES INTENT SCHEMA HTTPS Service

7 COMPONENTS OF A CUSTOM SKILL A set of intents that represent actions that users can do with your skill A set of sample utterances that specify words and phrases An invocation name that identifies the skill A cloud-based service that accepts these intents and acts on them A configuration that combines all this, created in the developer portal

8 INTENTS OneshotTideIntent mapped to several sample utterances: OneshotTideIntent get high tide OneshotTideIntent get high tide for {City} OneshotTideIntent tide information for {City} OneshotTideIntent when is high tide in {City}... (many more sample utterances) Sample Utterance Invocation Name Alexa, get high tide for Seattle from Tide Pooler

(many more sample utterances) Slot Alexa, get high tide for Seattle from Tide Pooler

10 INTENTS MAPPED TO SAMPLE UTTERANCES OneshotTideIntent get high tide OneshotTideIntent get high tide for {City} OneshotTideIntent tide information for {City} OneshotTideIntent when is high tide in {City}... (many more sample utterances) This is called the Interaction Model

11 OneshotTideIntent get high tide OneshotTideIntent get high tide for {City} OneshotTideIntent tide information for {City} OneshotTideIntent when is high tide in {City}... (many more sample utterances) Alexa, get high tide for Seattle from Tide Pooler 1. The user s speech is streamed to the Alexa service in the cloud 2. Alexa service recognizes that Tide Pooler skill belongs to OneshotTideIntent 3. Alexa service structures into a request and sends the request to the skill service you ve defined.

13 INTERACT WITH A SKILL WITHOUT A SPECIFIC QUESTION OR REQUEST Alexa, Open Tide Pooler Alexa, Talk to Recipes Alexa, Play Trivia Master Alexa, Start Score Keeper

14 SKILL Skill Service Service Container Skill Interface Voice User Interface Configuration UTTERANCES SLOT TYPES INTENT SCHEMA HTTPS Service Alexa, get high tide for Seattle from Tide Pooler

15 TIME TO BUILD OUR SKILL COUNTRY INFO

16 OUR CUSTOM SKILL Alexa, ask Country Info about France We ll use C# for our Skill Service.NET Core app Use AWS Nuget packages We ll host our service in AWS Lambda (Serverless) We ll use a REST service that returns country About France. The capitol is Paris and the population is 66 million 710 thousand. information

17 COUNTRY INFO SERVICE REST service at

18 STEPS SKILL Step 1: Design a Voice User Interface Skill Service Skill Interface Step 2: Set Up the Skill Step 3: Write and Test the Code UTTERANCES SLOT TYPES INTENT SCHEMA HTTPS Service

19 DESIGN VOICE USER INTERFACE - UTTERANCES Alexa, ask Country Info the capitol of England Alexa, get the capitol of England from Country Info Alexa, ask Country Info about England CountryInfoIntent the capitol of {Country} CountryInfoIntent get the capitol of {Country} CountryInfoIntent country info for {Country} CountryInfoIntent what is the capitol of {Country} CountryInfoIntent about {Country} CountryInfoIntent tell me the capitol of {Country}
