Examples
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.
}
Remarks
The Result property obtains the recognition information as a RecognitionResult object.
RecognitionEventArgs is the base for the following classes:
RecognitionEventArgs derives from EventArgs.
