Overview of this book

Conversation as an interface is the best way for machines to interact with us using the universally accepted human tool that is language. Chatbots and voice user interfaces are two flavors of conversational UIs. Chatbots are real-time, data-driven answer engines that talk in natural language and are context-aware. Voice user interfaces are driven by voice and can understand and respond to users using speech. This book covers both types of conversational UIs by leveraging APIs from multiple platforms. We'll take a project-based approach to understand how these UIs are built and the best use cases for deploying them. We'll start by building a simple messaging bot from the Facebook Messenger API to understand the basics of bot building. Then we move on to creating a Task model that can perform complex tasks such as ordering and planning events with the newly-acquired-by-Google Dialogflow and Microsoft Bot framework. We then turn to voice-enabled UIs that are capable of interacting with users using speech with Amazon Alexa and Google Home. By the end of the book, you will have created your own line of chatbots and voice UIs for multiple leading platforms.

Tour Guide for Your City

Having got a taste of chatbots and their brief history, in this chapter we'll get our hands dirty by building your first chatbot. We will build a chatbot that will act as a city tour guide for the user. We will use popular tourist conversations, such as learning about the city, figuring out things to do, and searching for places to eat as example tasks. We will explore how to use the various tools in the toolkit to build a chatbot capable of performing these conversational tasks.
