Examples

The example below creates a handler for SpeechRecognizer.SpeechDetected or SpeechRecognitionEngine.SpeechDetected events. The handler initializes a display every time speech is detected and displays status information, including audio position.

_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);  
  };

Remarks

A SpeechDetected event is raised by the SpeechRecognizer and SpeechRecognitionEngine classes.

SpeechDetected events are generated when a recognition engine can identify audio input as human speech.

SpeechDetectedEventArgs derives from EventArgs.

Properties

Gets the position in the audio stream where speech was detected.
