Hands-On Chatbots and Conversational UI Development

By: Srini Janarthanam

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.

Built-in intents and slot types

Alexa has a library of built-in intents and slot types that can be used in any skill that we build. Using built-in intents come with their own set of advantages. As a developer, you don't have to provide sample utterances and whenever Alexa gets updated with more sample utterances, your skill gets a boost. Also, it makes it easy for users to remember a simple set of phrases across skills to get things done with Alexa.

Here is a set of standard built-in intents that you can use:

Built-in intents Description
Amazon.YesIntent Whenever the user says yes, yeah, or something similar
Amazon.NoIntent When the user says no, no thanks, or something similar
Amazon.CancelIntent When the user asks to cancel the current task, such as cancel, never mind, or forget it
Amazon.HelpIntent When the user asks for help (help, can you help me)
