win7下，vs2008，用过一个C#的，忘了在什么地方下的了。
用法：
SRecognition sr;
string[] fg = { "东方", "西方", "南方", "北方" };
sr = new SRecognition(fg);
sr.BeginRec(textBox1);// 开始，textBox1输出结果
//sr.over();//停止
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Speech;
using System.Speech.Recognition;

Answer 3

整理成一份最简单的。vs2008编译，win7下，运行正常。新建项目需要引用.net的System.Speechhttp://files.cnblogs.com/slowhand/SR.zip

Answer 4

我测试过了，win7下能运行。。
控制台程序能在win2003运行，但是winFrom程序不能，会出现
这个错误。
未处理 System.ArgumentException
  Message=值不在预期的范围内。
  Source=System.Speech

Answer 5

木有2003环境，囧。目测这个System.Speech应该是.net FrameWork3.5 里面自带的

Answer 6

在win2003环境下运行就要报错，但是在win7下就不能正常运行。。但是MSDN上面的实例在控制台程序能在2003运行。我不清楚是哪个环节出问题了。
