Remarks

An instance of SpeechRecognitionRejectedEventArgs is created when the SpeechRecognitionEngine.SpeechRecognitionRejected event is raised.

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.

                delegate(object sender, SpeechHypothesisEventArgs eventArgs)
                {
                    DisplayResult(eventArgs);
                };
