public class SpeechDetectedEventArgs : EventArgs

NameDescription
System_CAPS_pubpropertyAudioPosition

Gets the position in the audio stream where speech was detected.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

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

SpeechDetected events are generated when a recognition engine can identify audio input as human speech.

SpeechDetectedEventArgs derives from EventArgs.

The example below creates a handler for SpeechRecognizer.SpeechDetected or SpeechRecognitionEngine.SpeechDetected events. The handler initializes a display every time speech is detected and displays status information, including audio position.

_recognizer.SpeechDetected +=
  delegate(object sender, SpeechDetectedEventArgs eventArgs) 
  {

    // Clear previous recognition information.
    _audioDeviceStatusLabel.Enabled = true;
    _audioDeviceStatusLabel.Visible = true;
    Utils.DisplayAudioInputFormat(_audioStateLabel, _recognizer);
    Utils.DisplayRecognizerState(_recognizerStateLabel, _recognizer.State);
    Utils.DisplaySpeechDetected(_speechDetectedLabel, eventArgs.AudioPosition);
  };
