Remarks

When using the shared recognizer, the recognizer state is a global setting. If one application changes the recognizer state, it will affect all other applications connected to the shared recognizer. For this reason, applications using a shared recognizer should take great caution before calling SetRecoState.

Changing the recognition state leads to a SPEI_RECO_STATE_CHANGE event for all interested recognition contexts.
