The ISRNotifySink interface is used by an engine to return status information to the application. This interface is passed to the engine by the speech-recognition enumerator when it registers the engine. All functions are optional and may or may not be supported by an engine.
All notifications are sent as soon as possible, even though the engine has not begun processing the audio data. These notifications are generally for the application's user interface and exist to provide immediate feedback.
The ISRNotifySink interface has these member functions:
AttribChanged | UtteranceBegin |
Interference | UtteranceEnd |
Sound | VUMeter |
