ISpSREngineSite::UpdateRecoPos
ISpSREngineSite::UpdateRecoPos returns the current position of the recognizer in the stream to SAPI. An engine should call this regularly, up to several times a second, regardless of whether it is recognizing speech or silence.
This method can only be called while the SR engine is inside a ISpSREngine::RecognizeStream call, although it can be called on any thread.
