解决方案

此版本编译。您不清楚是否是编译错误或运行时错误。如果您的问题是编译错误，则此版本解决了该错误。因为它是C＃代码，大小写必须匹配。我纠正了< event args =>使用大写和小写的条款如下：< SpeechRecognizedEventArgs> 。

解决方案

This version compiles. You weren''t clear enough to say whether it was a compile error or a run-time error. If your problem was a compile error, this version resolves that. Because it is C# code, the upper and lower case must match. I corrected the <event args=""> clauses to use upper and lower case like this: <SpeechRecognizedEventArgs>.

            try
            {
               
                recognitionEngine = new SpeechRecognitionEngine();
                DictationGrammar dg = new DictationGrammar();
                dg.Name = "Dictation Grammar";
                recognitionEngine.LoadGrammar(dg);
                recognitionEngine.SetInputToDefaultAudioDevice();
                //recognitionEngine.SetInputToWaveFile(@"C:\Users\Deep\Music\New folder\mp3.wav");
                recognitionEngine.SetInputToDefaultAudioDevice();  // Gets sound from microphone
                recognitionEngine.EndSilenceTimeout = new TimeSpan(0, 0, 2);
                // Following two lines are not needed. They cause error!
                //recognitionEngine.Recognize();
                //recognitionEngine.RecognizeAsync();
                recognitionEngine.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(reco_SpeechHypothesized);
                recognitionEngine.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(reco_SpeechRecognized);

            }
            catch (Exception e)
            {

Revised Solution - 27 March 2013 2:44PM EDT:

    static void speech1(object sender, SpeechRecognizedEventArgs e)
    {
        if (e.Result.Text == "record")
        {
            showRecord();
        }
        else if (e.Result.Text == "exit")
        {
            Application.Exit();
        }
    }

    private void button1_Click(object sender, EventArgs e)
    {
        showRecord();
    }
    static void showRecord()
    {
    record r=new record();
    r.show();
    }
}
public class record
{
     public  void show() { }
}
