ISpVoice::SpeakCompleteEvent (SAPI 5.4)
Microsoft Speech API 5.4
ISpVoice::SpeakCompleteEvent returns an event handle that will be signaled when the voice has completed speaking all pending requests. This is similar to the functionality provided by ISpVoice::WaitUntilDone, but allows the caller to wait on the event handle.
[local] HANDLE SpeakCompleteEvent ( void );
The caller should not call CloseHandle(), nor should the caller ever use the handle after releasing the COM reference to this voice.
