SpeechRecognitionRejectedEventArgs Class

Class passed to handlers of events generated as when a speech recognition engine fails to identify a phrase from input.

Namespace: System.Speech.Recognition
Assembly: System.Speech (in system.speech.dll)

public class SpeechRecognitionRejectedEventArgs : RecognitionEventArgs
/** @attribute SerializableAttribute() */ 
public class SpeechRecognitionRejectedEventArgs extends RecognitionEventArgs
public class SpeechRecognitionRejectedEventArgs extends RecognitionEventArgs
Not applicable.

SpeechRecognitionRejectedEventArgs derives from RecognitionEventArgs.

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

SpeechRecognitionRejected events (SpeechRecognizer.SpeechRecognitionRejected and SpeechRecognitionEngine.SpeechRecognitionRejected) are generated when no speech recognition hypothesis scores high enough for a recognition engine to accept it.

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)
