Question

这是我的代码，我希望根据我给定的输入不断获得结果，但应用程序只提供一次输出然后什么都不做。我认为必须循环结果类，实际上不确定在哪里。请帮帮我:) SpeechRecognizer speechRecognizer = new SpeechRecognizer（）;

    public MainPage()
    {
        this.InitializeComponent();
        InitializeSpeechRecognizer();

    }
    private async void InitializeSpeechRecognizer()
    {
        speechRecognizer.RecognitionQualityDegrading += speechRecognizer_RecognitionQualityDegrading;
        await speechRecognizer.CompileConstraintsAsync();
        // Start recognition.

        SpeechRecognitionResult speechRecognitionResult= await speechRecognizer.RecognizeAsync();
            textBox1.Text = speechRecognitionResult.Text;
        // Compile the constraint.


    }

    private async void speechRecognizer_RecognitionQualityDegrading(
Windows.Media.SpeechRecognition.SpeechRecognizer sender,
Windows.Media.SpeechRecognition.SpeechRecognitionQualityDegradingEventArgs args)
    {
        // Create an instance of a speech synthesis engine (voice).
        var speechSynthesizer =
            new Windows.Media.SpeechSynthesis.SpeechSynthesizer();

        // If input speech is too quiet, prompt the user to speak louder.
        if (args.Problem == Windows.Media.SpeechRecognition.SpeechRecognitionAudioProblem.TooQuiet)
        {
            // Generate the audio stream from plain text.
            Windows.Media.SpeechSynthesis.SpeechSynthesisStream stream;
            try
            {
                stream = await speechSynthesizer.SynthesizeTextToStreamAsync("Try speaking louder");
                stream.Seek(0);
            }
            catch (Exception)
            {
                stream = null;
            }


        }
    }
}

}

您应该注册 SpeechRecognized 事件，并将结果文本设置为事件处理程序中的文本框。它只工作一次，因为InitializeSpeechRecognizer被调用一次，这不是正确的地方。

编辑：最简单的实现就是这样;

SpeechRecognizer sr = new SpeechRecognizer();
sr.SpeechRecognized += (s, e) => {
            Console.WriteLine("Recognized Text :{0}, Confidence {1}",
                               e.Result.Text,e.Result.Confidence); 
        };

当我说话时，它只提供一次输出（结果），并且对下一次输入无效
