Simple SAPI – Text to Speech and Speech Recognition

This is a simple C++ integration of basic Text to Speech (TTS) and Speech Recognition (SR) features provided by the Microsoft Speech API 5.3. The SAPI itself if a very good and full featured API, but a little arcane for first time users. This code is intended to be an easy way to get basic functionality without much effort.

It provides a basic interface for TTS, and a dynamic ‘command and control’ grammar for SR (as opposed to the ‘dictation’ grammar which is easier to get working but fairly useless for games). You can specify a word or phrase at runtime and this code will create a grammar rule to listen for it.

The download includes source code and a sample Visual Studio 2008 project.

Hi Henry,

I’m looking to read your Applied Research Project from last year, and I was wondering if you had online copies available?

Regards,
Chris
