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.

Backing up the Alexa skill

In this section, you will learn how to back up the Alexa Cooking App skill you built. Everything you have built so far in the ASK can be exported to JSON, and later, you can restore the JSON to recreate an Alexa skill.

  1. Log in to the Alexa console using the browser.
  2. Once you log in, go to Cooking App Skill.
  3. On the left-hand menu, there is a JSON Editor.

The following screenshot shows the JSON Editor menu:

  1. On the right-hand side, you will see the JSON that describes the schema definition of the Alexa skill you built. Note that there is not a direct way to export the file from the web, so you would need to copy and paste the JSON into the file.

The following screenshot shows the JSON schema of the Alexa skill you built:
