_recognizer.SpeechDetected +=  
  delegate(object sender, SpeechDetectedEventArgs eventArgs)   
  {  

    // Clear previous recognition information.  
    _audioDeviceStatusLabel.Enabled = true;  
    _audioDeviceStatusLabel.Visible = true;  
    Utils.DisplayAudioInputFormat(_audioStateLabel, _recognizer);  
    Utils.DisplayRecognizerState(_recognizerStateLabel, _recognizer.State);  
    Utils.DisplaySpeechDetected(_speechDetectedLabel, eventArgs.AudioPosition);  
  };
