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.

In this chapter, we've learned about the components of chatbots—intents, slots, and utterances—and the role that each of them plays.

Next, we learned how to design conversation flows, starting with an ideal conversation and converting it into a conversation flow diagram. Using flowchart software, we created conversation flow diagrams to help visualize how our chatbot will interact with the users.

We talked about the best practices for creating a chatbot, from handling errors to designing your conversations to work well on chatbots, from the tone of voice to good chatbot use cases.

The last part of this chapter introduced Amazon Alexa and Amazon Lex. We learned about the similarities and differences between the two types of chatbot as well as a bit of background into them both.
