Examples

The following example adds an event handler to a SpeechRecognitionEngine object. The handler outputs the new audio level to the console.

AudioLevelUpdatedEventArgs derives from EventArgs.

private SpeechRecognitionEngine sre;  

// Initialize the SpeechRecognitionEngine object.   
private void Initialize()  
{  
  sre = new SpeechRecognitionEngine();  

  // Add an event handler for the AudioLevelUpdated event.  
  sre.AudioLevelUpdated += new EventHandler<AudioLevelUpdatedEventArgs>(sre_AudioLevelUpdated);  

  // Add other initialization code here.  
}  

// Write the audio level to the console when the AudioLevelUpdated event is raised.  
void sre_AudioLevelUpdated(object sender, AudioLevelUpdatedEventArgs e)  
{  
  Console.WriteLine("The audio level is now: {0}.", e.AudioLevel);  
}

Remarks

When they are raised, the SpeechRecognitionEngine.AudioLevelUpdated and SpeechRecognizer.AudioLevelUpdated events pass an instance of AudioLevelUpdatedEventArgs to the handler for the associated event.

The AudioLevel property gets the new level of audio input when the SpeechRecognitionEngine.AudioLevelUpdated or SpeechRecognizer.AudioLevelUpdated event is raised.

The AudioLevel property of the SpeechRecognizer and SpeechRecognitionEngine classes provides the current level of the audio input to the speech recognition engine.
