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.

Testing the whole bot

Now that we have created all of the Lambdas and tested that they all work, we can put it all together and build our chatbot. On the Lex console for this chatbot, go through each of the intents and make sure that they are all being fulfilled using the correct Lambda, and then we can click Build at the top of the page.

Once it has finished building, we can start testing it out. We can start with finding a product. Typing I want to buy a shirt starts the productFind intent flow, and we can find the stock levels of the found item:

When we get shown a product, we should also be asked whether we want to add this to our cart. No matter our answer, we should then be asked whether we want to checkout, add another item, or save our cart. We need to try each of these methods, starting with adding another item:
