因为挑战杯的项目和语音有关，所以在网上找了一些这方面的资料。发现微软的sapi是一个不错的东西。
下面的程序大部分都是从msdn中得到的，自己都还没有把sdk的文档看明白:(
有兴趣的可以参见：http://www.microsoft.com/china/community/program/originalarticles/techdoc/cnspeech.mspx
如果找不到tlbimp命令，可以参见：http://blog.csdn.net/wayne92/archive/2006/04/08/655420.aspx
程序如下：
using system;
using system.drawing;
using system.collections;
using system.componentmodel;
using system.windows.forms;
using system.data;
using system.threading;
using dotnetspeech; //这个是要用tlbimp命令生成的。
/**//*ps：发现这样更简单：项目->添加引用->com 选择microsoft speech object library，就添加了speechlib（和生成的dotnetspeech一样）*/
