Voice User Interface Projects

By: Henry Lee

Overview of this book

From touchscreen and mouse-click, we are moving to voice- and conversation-based user interfaces. By adopting Voice User Interfaces (VUIs), you can create a more compelling and engaging experience for your users. Voice User Interface Projects teaches you how to develop voice-enabled applications for desktop, mobile, and Internet of Things (IoT) devices. This book explains in detail VUI and its importance, basic design principles of VUI, fundamentals of conversation, and the different voice-enabled applications available in the market. You will learn how to build your first voice-enabled application by utilizing DialogFlow and Alexa’s natural language processing (NLP) platform. Once you are comfortable with building voice-enabled applications, you will understand how to dynamically process and respond to the questions by using NodeJS server deployed to the cloud. You will then move on to securing NodeJS RESTful API for DialogFlow and Alexa webhooks, creating unit tests and building voice-enabled podcasts for cars. Last but not the least you will discover advanced topics such as handling sessions, creating custom intents, and extending built-in intents in order to build conversational VUIs that will help engage the users. By the end of the book, you will have grasped a thorough knowledge of how to design and develop interactive VUIs.

Summary

Continuing from Chapter 6, Building a Cooking Application Using Alexa, you applied advanced topics, such as creating dialog models to collect missing slots, and applied them to the Henry's Kitchen app. Also, you learned to manage and save application state to Microsoft Azure Redis in order to handle more complex conversation flows. The chapter also introduced more comprehensive logging, which allows the Node.js server handling Alexa requests to log events and data to Microsoft Azure Blob storage. You learned to download the logs and review them to understand the voice application flows and interaction between Alexa and the server. Finally, after understanding the submission policy, the application was submitted to the marketplace.
In the next chapter, you will utilize and slightly modify the same server code, and learn to convert an Alexa skill to a Google Dialogflow...
