因為挑戰(zhàn)杯的項目和語音有關(guān)，所以在網(wǎng)上找了一些這方面的資料。發(fā)現(xiàn)微軟的sapi是一個不錯的東西。

下面的程序大部分都是從msdn中得到的，自己都還沒有把sdk的文檔看明白:(

有興趣的可以參見：http://www.microsoft.com/china/community/program/originalarticles/techdoc/cnspeech.mspx

如果找不到tlbimp命令，可以參見：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;                //這個是要用tlbimp命令生成的。
/**//*ps：發(fā)現(xiàn)這樣更簡單：項目->添加引用->com 選擇microsoft speech object library，就添加了speechlib（和生成的dotnetspeech一樣）*/
