SpeechDetectedEventArgs Class
Returns data from the SpeechDetected event.
Assembly: System.Speech (in System.Speech.dll)
The SpeechDetected event is raised by the SpeechRecognizer and SpeechRecognitionEngine classes.
SpeechDetected events are generated when a recognition engine can identify input audio as human speech.
SpeechDetectedEventArgs derives from System.EventArgs.
In the example below, a handler is created for SpeechDetected() events which 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.DisplayAudioInputStatus(_audioDeviceStatusLabel, _recognizer.AudioStatus);
Utils.DisplaySpeechDetected(_speechDetectedLabel, eventArgs.AudioPosition);
};
