The document outlines the creation of an Alexa skill using AWS, focusing on the frameworks of automated speech recognition (ASR) and natural language understanding (NLU) that enable brands to connect with customers. It details various components such as the Alexa Skills Kit, voice user interface programming, and skill development resources that support building unique app experiences. Additionally, it emphasizes the use of services like AWS Lambda and DynamoDB for managing skill functionality and data persistence.

- 21. Upload your code Setup your triggers Runs only when triggered Pay only for the compute time used! Deploy your Back-End AWS Lambda
- 22. Language (Interaction) Model Skill Code (Lambda Function) Skill Publish Information Alexa Developer Portal Alexa Developer PortalAWS Console Local Code+ Skill Development
- 23. Local Code Language (Interaction) Model Skill Code (Lambda Function) Skill Publish Information Skill Development alexa.design/askcli
- 24. ASK Command Line Interface Based on Node JS ? Runs on Windows, Mac, Linux Manage Skills Programmatically ? uses Skills Management API (SMAPI) Deploy Skill Lambda Functions ? uses AWS CLI under the hood alexa.design/askcli ASK CLI != AWS CLI
- 25. Skill Manifest CLI mapping to profile information Front-End Back-End
- 27. LET’S BUILD A SKILL
- 28. Persistence
- 29. ? Remember: AWS Lambda maintains no state across executions ? As a Skill Builder, you therefore have two layers of memory: Session Attributes Persistent Attributes Expire when session ends Persist across sessions Memory
- 30. Sessions Attributes const attributesManager = handlerInput.attributesManager; const sessionAttributes = attributesManager.getSessionAttributes(); /* YOUR CODE LOGIC HERE */ sessionAttributes["profile"] = ...; attributesManager.setSessionAttributes(sessionAttributes);
- 31. Connect to Amazon DynamoDB const skillBuilder = Alexa.SkillBuilders.standard(); exports.handler = skillBuilder .addRequestHandlers( // ... handlers ) .addRequestInterceptors( // ... request interceptors ) .addResponseInterceptors( // ... response interceptors ) .addErrorHandlers(ErrorHandler) .withTableName("theFoodie") .withAutoCreateTable(true) .lambda(); Table
- 32. Fully managed Low cost Predictable performance Massively scalable Highly available
- 33. Persistent Attributes const attributesManager = handlerInput.attributesManager; let persistentAttributes = await attributesManager.getPersistentAttributes(); persistentAttributes.profile.allergies = "shellfish"; attributesManager.setPersistentAttributes(persistentAttributes); attributesManager.savePersistentAttributes();
