这是我目前的代码: (之后我会解释我的问题)

Choices sList;
Grammar gr;
SpeechRecognitionEngine sRecognize = new SpeechRecognitionEngine();

private void BtnStartLuister_Click(object sender, EventArgs e)
    {
        sList = new Choices();
        sList.Add(new string[] { "hallo", "ik", "ben", "Ken", "zoek", "exit", "leeg", "stop", "add" });
        gr = new Grammar(new GrammarBuilder(sList));
        BtnStartLuister.Enabled = false;
        BtnStopLuister.Enabled = true;
        try
        {
            //sRecognize.MaxAlternates = 0;
            sRecognize.RequestRecognizerUpdate();
            sRecognize.LoadGrammar(gr);
            sRecognize.SpeechRecognized += sRecognize_SpeechRecognized;
            sRecognize.SetInputToDefaultAudioDevice();
            sRecognize.RecognizeAsync(RecognizeMode.Multiple);
            sRecognize.Recognize();
        }

        catch
        {
            return;
        }
    }
    private void BtnStopLuister_Click(object sender, EventArgs e)
    {
        sRecognize.RecognizeAsyncStop();
        BtnStartLuister.Enabled = true;
        BtnStopLuister.Enabled = false;
    }
    private void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {

        switch (e.Result.Text)
        {
            case "exit": { Application.Exit(); break; }
            case "stop": { BtnStopLuister_Click(sender, e); break; }
            case "zoek": { btnZoek_Click(sender, e); break; }
            case "add": { VoegToeBtn_Click(sender, e); break; }
            case "leeg": { tbWoord.Clear(); break; }
            default: { tbWoord.Text = tbWoord.Text + e.Result.Text.ToString() + " "; break; }
        }
    }

因此,如果我点击' BtnStartLuister',它将开始收听sList中的单词。效果很好,并将它们输出到tbWoord(我的表单中的文本框),如果是默认情况。 现在实际问题是:如果我按下按钮' BtnStopLuister',它就会停止收听等等。如果我按下“BtnStartLuister”#39;再次,然后说"肯"例如,它输出" Ken"的两次即可。我试过调试,似乎有一些替代品,e.Result携带。对我很好,但我不希望他们输出到我的文本框。

有谁知道如何解决这个问题? 任何帮助将不胜感激:)

(顺便说一下,我对C#(和一般编程)很陌生,对不起,如果有一些变量名称部分用荷兰语表示)

CodeCaster在评论中说了什么:

sRecognize.SpeechRecognized += sRecognize_SpeechRecognized; 
  

每次BtnStartLuister_Click方法运行时,您都会订阅该事件。取消订阅停止按钮事件处理程序。"
