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.

Basic Voice Commands

In this section, I'll cover some voice commands that you can use to interact with your Android auto podcast. Essentially, Android Auto uses Google Assistant, so to activate the voice command, you initiate with the "OK Google" wake word.

Then you can use following voice commands.

  • Play Andromeda on Henry podcast service: "Henry podcast service" is the label that you applied in the MusicService class of the MyPodCast project. "Andromeda" is the title of the song. When this command is invoked, it will invoke the OnPlayFromSearchImpl search from MusicService.
  • Stop playing: Stops playing podcast.
  • Resume: Resumes playing.
  • Play next: Plays next podcast.
  • Play previous: Plays previous podcast.
