Overview

This repo contains the walk through for a 2 hour tutorial on adding speech to bots.

In this tutorial we will walk you through two scenarios for integrating speech to text (STT) and text to speech (TTS) capabilities.

The first scenario is based on the JFK Hoover Bot and will showcase how you integrate STT and TTS capabilities into a web app. You will also learn about integrating a custom voice.

The Hoover Bot is a single-page Web app that works in any modern browser and provides a conversational interface to The JFK Files. The JFK Files is a Web app that lets you search a corpus of documents related to the assassination of President John F. Kennedy on November 22, 1963, released by the United States government. Microsoft has presented this technology demonstration, which showcases the power of Azure Cognitive Search, on several occasions.

The second scenario is based on the Study Bot sample which showcases how to integrate STT capabilities into a C# UWP application. This application, lets users learn study terms in three subjects: Geology, Biology and Sociology through a conversational experience. The goal is to enable a more engaging study epxerience.

5. msbot and Dipatch CLI tools

6. Knowledge of .bot files

7. Knowledge of ASP.Net Core and asynchronous programming in C#
