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.

Logging application events and data

Until now, you have managed to log application events and data using console.log. But logging to the Visual Studio Code console is only useful when you are debugging locally on your machine. In production, you need an easy way to view the log when an error occurs. This chapter deals with more complex scenarios and requires a solid logging strategy in order to capture the requests and responses going into and out of the web service endpoint. You will take advantage of Microsoft Azure Blob storage to log application event data. Microsoft Azure Blob storage offers many compelling advantages:

  • It is cheap. Microsoft Azure Blob will cost you $0.002 GB/month (https://bit.ly/2dLTE5l), which is virtually free as you will be using no more than 1-2 GB for a small application per month.
  • It is reliable. You do not have to manage expensive storage array...
