RecognitionEventArgs Class
Provides information about speech recognition events.
System::EventArgs
System.Speech.Recognition::RecognitionEventArgs
System.Speech.Recognition::SpeechHypothesizedEventArgs
System.Speech.Recognition::SpeechRecognitionRejectedEventArgs
System.Speech.Recognition::SpeechRecognizedEventArgs
Assembly: System.Speech (in System.Speech.dll)
The RecognitionEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The Result property obtains the recognition information as a RecognitionResult object. For more information about speech recognition events, see Using Speech Recognition Events.
RecognitionEventArgs is the base for the following classes:
RecognitionEventArgs derives from EventArgs.
The following example attaches a handler for the SpeechHypothesized, SpeechRecognized, and SpeechRecognitionRejected events of the speech recognizer. The event argument types for the three events all derive from RecognitionEventArgs, which is used as the event data parameter in the handler.
// Initialize the speech recognizer. private void Initialize(SpeechRecognitionEngine recognizer) { // Attach handlers for the SpeechHypothesized, SpeechRecognitionRejected, // and SpeechRecognized events. recognizer.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(DisplayResult); recognizer.SpeechRecognitionRejected += new EventHandler<SpeechRecognitionRejectedEventArgs>(DisplayResult); recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(DisplayResult); // Add other initialization code here. } // Handle the SpeechHypothesized, SpeechRecognitionRejected, // and SpeechRecognized events. private void DisplayResult(object sender, RecognitionEventArgs e) { if (e is SpeechHypothesizedEventArgs) { Console.WriteLine("Speech hypothesized:"); } else if (e is SpeechRecognitionRejectedEventArgs) { Console.WriteLine("Speech recognition rejected:"); } else if (e is SpeechRecognizedEventArgs) { Console.WriteLine("Speech recognized:"); } // Add code to handle the event. }
