StateChangedEventArgs Class

The StateChanged event is raised by the

SpeechRecognitionEngine class.

System state can be changed programmatically by setting the Enabled() property of a recognition engine or through the Speech member of ControlPanel.

StateChangedEventArgs derives from [System.EventArgs] and is passed to handlers for StateChanged events.

The example below updates a display based on the state information provided by and instance of RecognizerState obtained from the RecognizerState property of an instance of StateChangedEventArgs passed to a handler for a StateChanged.

//Make sure that _recognizer and recognition start buttons are disabled if state is stopped.
//Reenable the start button to allow manual reenable if start is listening
_recognizer.StateChanged +=
    delegate(object sender, StateChangedEventArgs eventArgs) {
        _recognizerStateLabel.Text = "Speech Recognizer State: " + eventArgs.RecognizerState.ToString();
    };
