ISpSREngineSite (Windows Embedded CE 6.0)
1/6/2010
This interface gets audio data, retrieves grammar information, sends events, and returns recognition information to SAPI. It is implemented by SAPI and is called by an SR engine. After SAPI creates the SR engine, the engine obtains a pointer to ISpSREngineSite when the ISpSREngine::SetSite is called.
When to Implement
Only SAPI implements this interface.
