Question

我用C＃编写了一个语音识别引擎

    public partial class MainWindow : Window
    {

        SpeechRecognitionEngine _recognizer;
        SpeechSynthesizer sre = new SpeechSynthesizer();
        int count = 1;

    public MainWindow()
    {
        InitializeComponent();
        Initialize();
    }

    private void Initialize()
    {
        try
        {
            var culture = new CultureInfo("en-US");
            _recognizer = new SpeechRecognitionEngine(culture);
            _recognizer.SetInputToDefaultAudioDevice();
            _recognizer.LoadGrammar(GetGrammer());
            _recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(_recognizer_SpeechRecognized);

            _recognizer.RecognizeAsync(RecognizeMode.Multiple);

            sre.SelectVoiceByHints(VoiceGender.Male, VoiceAge.Child);
            sre.Rate = -2;

        }
        catch (Exception ex)
        {
            System.Windows.MessageBox.Show(ex.InnerException.Message);
        }
    }

    private static Grammar GetGrammer()
    {

        var choices = new Choices();
        //add custom commands
        choices.Add(File.ReadAllLines(@"Commands.txt"));
        //to add the letters to the dictionary
        choices.Add(Enum.GetNames(typeof(Keys)).ToArray());

        var grammer = new Grammar(new GrammarBuilder(choices));

        return grammer;
    }

    void _recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {

        string speech = e.Result.Text; 

    //to type letters in open application like notepad
   if (Enum.GetNames(typeof(Keys)).Contains(speech))
    {
        try
        {   //send the string to the application
            SendKeys.SendWait("{" + speech + "}");
        }
        catch (ArgumentException)
        {

        }            
    }  

    //handle custom commands
        switch (speech)
        {
             case "day":
                sre.Speak("Friday");
                break;
        }
    }       
}
// where speech receives the text which the user speaks and also present in the loaded grammar (text file)

我的代码生成一个语音识别引擎，如果用户询问＆＃34; day＆＃34;它回复＆＃34;星期五＆＃34;而这反过来又有一个＆＃34; day＆＃34;在里面。所以它继续循环并继续回复＆＃34;星期五＆＃34;。什么是在发言时停止发动机聆听的最佳方法。

注意：我知道语法可以改变为令人信服的方式，例如＆＃34;它是什么日子＆＃34;但我需要它作为＆＃34; day＆＃34;本身。

此外，我不提供可重现的代码，因为这个问题可能是我遗漏了一些基本的东西。我已尝试使用某些StackOverflow问题中建议的bool bAbleToListen=true;。但是，无法找到它有用

Answer 1

您正在将RecognizeMode.Multiple传递给RecognizeAsync方法。

多个的
      System.Speech.Recognition.RecognizeMode
的成员
摘要：
指定识别不会在之后终止   完成。

所以也许你希望它在Speak之后终止并重新开始？

_recognizer.SpeechRecognized += (sender, args) =>
{
    sre.Speak("trololo");
    _recognizer.RecognizeAsync(RecognizeMode.Single);
};

_recognizer.RecognizeAsync(RecognizeMode.Single);

如果语音合成器正在讲话，则不要运行收听代码。
