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.

Hosting and Enhancing the Android Auto Podcast

In the previous chapter, you created MusicService, MusicProvider, and MediaPlayer, and ran the Android media application on the mobile. In this chapter, you will use the experience you gained by utilizing the Microsoft Azure cloud offerings to develop the podcast backend using Node.js for MusicProvider and store streaming media sources in Microsoft Azure Storage. Then, you will learn how to configure and test MusicService on Android Auto using the desktop-header unit simulator and then run it in a real car. You will also learn some basic voice commands to interact with your Android Auto application. Finally, you will learn about the Android Auto certification process.

In this chapter, we will cover the following topics:

  • Creating the Node.js media's metadata provider
  • Refactoring MusicProvider to retrieve the media metadata from...
