基于Windows Sdk 与visual C++2008 在微软平台上构架自己的语音识别引擎（适用于windows 2000/xp2003/vista   windows CE /mobile），本项目开源，源码请留下你们的Email，我给大家发

 

本人闲来无事，自行开发了一个小型的语音识别引擎，搭建起在微软平台上的语音识别框架服务体系，

鉴于本人个人力量有限，为了将语音识别引擎做的功能更加强悍，强大，

现在将该系统开源，需要源码的请在本人CSDN博客下留下EMail，

本系统属于系统框架，搭建起一个语音识别的引擎服务框架，

在微软平台上畅通无阻，

 

现在将本系统构架公布一下，

并贴出相关核心源码，源码体积为37M，编译后为3M，

适用于windows 2000/xp2003/vista   windows CE /mobile
