SpeechRecognitionEngine.InitialSilenceTimeout Property
Gets and set the maximum amount of silence that can precede audio input before a recognition engine generates an error.
Assembly: System.Speech (in System.Speech.dll)
If a recognition engine receives only silence -- as opposed to background noise-- for longer than the time specified by InitialSilenceTimeout an error will occur.
For asynchronous recognition operations and emulation (initiated by calls to RecognizeAsync and EmulateRecognizeAsync), a RecognizeCompleted is generated receiving an instance of RecognizeCompletedEventArgs with its InitialSilenceTimeout set to true.
For synchronous recognition operations and emulation (initiated by calls to Recognize and EmulateRecognize a null value rather than a valid RecognitionResult is returned.
