ISpVoice::WaitUntilDone (SAPI 5.4)
Microsoft Speech API 5.4
ISpVoice::WaitUntilDone blocks the caller until either the voice has completed speaking or the specified time interval has elapsed.
HRESULT WaitUntilDone( ULONG msTimeout );
[in] Timeout period in milliseconds. INFINITE may be used to prevent this method from timing out.
This call may be used after a single asynchronous Speak (or SpeakStream) call, or after several calls have been queued. In either case it will return only after all pending calls have been completed (or after the specified time interval has elapsed).
