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.
