ISpVoice::Pause (SAPI 5.4)
Microsoft Speech API 5.4
ISpVoice::Pause pauses the voice at the nearest alert boundary and closes the output device, allowing access to pending speak requests from other voices.
HRESULT Pause ( void );
Calling ISpVoice::Pause while the voice is not speaking increments the pause count and will put the voice into a paused state until ISpVoice::Resume is called the same number of times.
The voice maintains a pause count, so each call to pause must be balanced with a corresponding call to ISpVoice::Resume.
The default alert boundary is at the beginning of each word. See ISpVoice::SetAlertBoundary for details.
