Hands-On Chatbot Development with Alexa Skills and Amazon Lex

By: Sam Williams

Overview of this book

Have you ever wondered how Alexa apps are made, how voice-enabled technologies work, or how chatbots function? And why tech giants such as Amazon and Google are investing in voice technologies? A better question is: why should I start developing on these platforms? Hands-On Chatbot Development with Alexa Skills and Amazon Lex covers all features of the Alexa Skills kit with real-world examples that help you develop skills to integrate Echo and chatbots into Facebook, Slack, and Twilio with the Amazon Lex platform. The book starts with teaching you how to set up your local environment and AWS CLI so that you can automate the process of uploading AWS Lambda from your local machine. You will then learn to develop Alexa Skills and Lex chatbots using Lambda functions to control functionality. Once you’ve come to grips with this, you will learn to create increasingly complex chatbots, integrate Amazon S3, and change the way Alexa talks to the user. In the concluding chapters, we shift our focus to Amazon Lex and messaging chatbots. We will explore Alexa, learn about DynamoDB databases, and add cards to user conversations. By the end of this book, you will have explored a full set of technologies that will enable you to create your own voice and messaging chatbots using Amazon.

  1. Cards are a great way to provide more information to the user without large blocks of text. Adding cards also allows you to provide buttons that give the user options for how to respond.
  2. No, all of the attributes are optional, but a title and subtitle are recommended.
  3. You'd use a search query slot type when there is a huge range of values that a user could enter. Creating a slot with everything would take too long and would still miss a lot of possible values.
  4. Yes, but you can't populate a search query slot and another slot in the same utterance.
  5. In Lex, the monitoring tab has a menu where it displays all of the missed intents. These can be looked through and added directly to an intent if needed.
