ISpNotifySink::Notify (SAPI 5.3)
Microsoft Speech API 5.3
ISpNotifySink::Notify is called by an ISpNotifySource object to notify the sink when the state of the notify source has changed.
HRESULT Notify ( void );
The only interface that can be called on an event source object is ISpEventSource::GetEvents. The Notify() method should only signal another thread to process the notification (for example, a Win32 event or an I/O completion port), and if needed, call ISpEventSource::GetEvents. Do not call any other methods.
