SpeechRecognitionRejectedEventArgs Class

The SpeechRecognitionRejected event is raised by the SpeechRecognizer and SpeechRecognitionEngine classes.

SpeechRecognitionRejected events are generated when no speech recognition hypothesis scores high enough for a recognizer to accept it.

Detailed information about rejected phrases is available through the Result property.

SpeechRecognitionRejectedEventArgs derives from RecognitionEventArgs.

In the example below, a delegate is defined to use the instance of SpeechRecognitionRejctedEventArgs passed to the handler for SpeechRecognitionRejected events to display information about rejected phrases.

// Handles the SpeechHypothesis event and displays the Hypothesis result.
            _recognizer.SpeechHypothesis +=
                delegate(object sender, SpeechHypothesisEventArgs eventArgs)
                {
                    DisplayResult(eventArgs);
                };
