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.

Previously, in Chapter 1, Introduction, you used SSML to manipulate tone, rate, and pitch to make speech sound more human. In this section, you will modify the Default Welcome intent to sound more exciting and also introduce an opening sound, so that when the user first uses the FortuneCookie, they will hear a thunder sound and then the FortuneCookie will welcome the user with excitement. Using SSML and sound brings that pop to your application, making it more fun to engage with. You can find more information on SSML that Dialogflow supports at http://bit.ly/2BHBQmq.

Previously, Default Welcome intent simply greeted the user with Hello, Welcome...
