SpeechHypothesizedEventArgs Class

Returns notification from SpeechRecognitionEngine.SpeechHypothesized or SpeechRecognizer.SpeechHypothesized events.

This class supports the .NET Framework infrastructure and is not intended to be used directly from application code.


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

public class SpeechHypothesizedEventArgs : RecognitionEventArgs

The SpeechHypothesizedEventArgs type exposes the following members.

Public propertyResultGets the recognition result data associated with the speech recognition event. (Inherited from RecognitionEventArgs.)

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

A SpeechHypothesized event is raised by the SpeechRecognizer and SpeechRecognitionEngine classes.

You can obtain detailed information about a tentatively recognized phrase by using the Result property.

Numerous SpeechHypothesized events are generated as a recognition engine attempts to identify an input phrase. Typically, handling these events is useful only for debugging.

SpeechHypothesizedEventArgs derives from RecognitionEventArgs.

The example below creates a handler for SpeechRecognizer.SpeechHypothesized or SpeechRecognitionEngine.SpeechHypothesized events. The handler uses an instance of SpeechHypothesizedEventArgs to return and display information about a tentatively recognized phrase.

// Create a handler for the SpeechHypothesized event.
recognizer.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(recognizer_SpeechHypothesized);

// Handle the event and display the hypothesized result.
void recognizer_SpeechHypothesized (object sender, SpeechHypothesizedEventArgs e)
    Console.WriteLine("Hypothesized text: " + e.Result.Text);
