语音识别引擎无法识别多次

Question

使用下面的代码，它可以工作，并返回第一个识别，但不是所有其他识别。我做错了什么？我是不是应该在某种循环中？

    public void Transcribe()
    {
        SpeechRecognitionEngine SRE = new SpeechRecognitionEngine();
        SRE.LoadGrammar(new DictationGrammar());

        SRE.SetInputToWaveFile(_fileName);
        SRE.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(SRE_SpeechRecognized);
        SRE.RecognizeCompleted += new EventHandler<RecognizeCompletedEventArgs>(SRE_RecognizeCompleted);
        SRE.RecognizeAsync(RecognizeMode.Multiple);    
    }

    void SRE_RecognizeCompleted(object sender, RecognizeCompletedEventArgs e)
    {
        Console.WriteLine(e.Result.Text);
    }

    void SRE_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {            
    }

Answer 1

使用SpeechRecognized作为事件处理程序来执行Console.WriteLine()。我刚才也遇到了同样的情况。
