SpeechRecognizeEngine不触发事件

问题描述

我已经使用了Mycrosoft语音识别引擎，该引擎工作正常，但未引发SpeechRecognized和SpeechHypothesized事件.
代码在下面给出

Hi,
I have used Mycrosoft Speech Recognize Engine, that is working fine, but not firing SpeechRecognized and SpeechHypothesized event.
Code is given below

SpeechRecognitionEngine _sre = new SpeechRecognitionEngine();
_sre.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);
            _sre.SpeechHypothesized+=new EventHandler<SpeechHypothesizedEventArgs>(_sre_SpeechHypothesized);
            _sre.SetInputToDefaultAudioDevice();
            _sre.RecognizeAsync(RecognizeMode.Multiple);

请任何人知道解决方案，请堆我.

推荐答案

//create an instance
SpeechRecognitionEngine recognitionEngine = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US"));

// Create and load a dictation grammar.
recognitionEngine.LoadGrammar(new DictationGrammar());

// Add a handler for the speech recognized event.
recognitionEngine.SpeechRecognized += new EventHandler<speechrecognizedeventargs>(recognitionEngine_SpeechRecognized);

// Configure input to the speech recognizer.
recognitionEngine.SetInputToDefaultAudioDevice();

void recognitionEngine_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
//recognize your speech here
}
