In this article, I will show you how to write a program which lists all the animations of the loaded characters which speak to us using synthesized speech, recorded audio, or text in a cartoon word balloon. Let us see in detail.

INTRODUCTION TO MICROSOFT AGENT:

The Microsoft Agent API affords services that support the display and animation of animated characters. Microsoft Agent consists of optional support for speech recognition as a result applications can respond to voice commands. Characters can react using synthesized speech, recorded audio, or text in a cartoon word balloon.

REQUIREMENTS:

To be proficient to use this technology, we must have:

The Microsoft Agent Core components.
The Microsoft Agent Characters Genie, Merlin, Robby, and Peedy.
The Microsoft Speech API 4.0a runtime.
The Microsoft Speech Recognition Engine.
The Lernout and Hauspie Text-to-Speech engines for at least US English.

All these components are available from

http://microsoft.com/products/msagent/downloads.htm

Please refer the following two articles for a clear idea.

The below program shows all the animations of the loaded character. It also plays all the animations of that particular character.
