如何从c＃中获取MIC的任何输入

Question

因此，我希望能够将用户所说的内容输入MIC并进行处理。我知道我可以用这个：

Choices c = new Choices();
        c.Add("hello test one two three");

        GrammarBuilder builder = new GrammarBuilder();
        builder.Append(c);

        Grammar g = new Grammar(builder);
        g.Name = "CMDS";
        reader.LoadGrammar(g);

        if (sReco != null)
            reader.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(SpeechRecognizedCallBack);
        if (sHypoth != null)
            reader.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(SpeechHypothesizedCallBack);
        if (sDetected != null)
            reader.SpeechDetected += new EventHandler<SpeechDetectedEventArgs>(SpeechDetectedCallBack);

获得某些词语，但我如何得到用户所说的任何内容。我听说过DictationGrammar，但我似乎无法让它发现我的声音。有人可以帮忙吗？代码示例也会有很多帮助。

感谢。
