C#语音识别命令确认？

Question

所以我让应用程序能够识别我所说的话。但是当我命令它执行任务时，如何让应用程序确认请求呢？

到目前为止，我有这个代码：

public partial class Form1 : Form
    {
        SpeechSynthesizer synth = new SpeechSynthesizer();
        SpeechRecognitionEngine sRecognize= new SpeechRecognitionEngine();

public Form1()
        {
            InitializeComponent();
        }

private void button1_Click(object sender, EventArgs e)
        {
              Choices sList = new Choices();
              sList.Add(new String[] { "Exit"});

              Grammar gr = new Grammar(new GrammarBuilder(sList));

              sRecognize.RequestRecognizerUpdate();
              sRecognize.LoadGrammar(gr);
              sRecognize.SpeechRecognized += sRecognize_SpeechRecognized;
              sRecognize.SetInputToDefaultAudioDevice();
              sRecognize.RecognizeAsync(RecognizeMode.Multiple);
              sRecognize.SpeechRecognitionRejected += sRecognize_SpeechRecognitionRejected;

}

private void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
      if (e.Result.Text == "Exit")
      {
              Application.Exit();
      }
  }
}

以我的问题为例：

我说，“退出”

申请确认：

确定要退出吗？

根据我的回答，应用程序会做出响应。

Yes 表示确认，No 表示请求取消。我必须做出哪些改变？

这样的？

private void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
  if (e.Result.Text == "Exit")
  {
           Choices sList = new Choices();
          sList.Add(new String[] { "Yes"});

          Grammar gr = new Grammar(new GrammarBuilder(sList));

          sRecognize.RequestRecognizerUpdate();
          sRecognize.LoadGrammar(gr);
          sRecognize.SpeechRecognized += delegate(object sender,     SpeechRecognizedEventArgs e)   
                  {   
                       Application.Exit();
                  };
          sRecognize.SetInputToDefaultAudioDevice();
          sRecognize.RecognizeAsync(RecognizeMode.Multiple);
  }

}
