[out] One of the input state flags contained in the SPRECOSTATE enumeration.
Return Values
| Value | Description |
|---|---|
| S_OK | Function completed successfully. |
| E_INVALIDARG | Invalid pointer. |
| FAILED(hr) | Appropriate error message. |
Remarks
This method determines whether audio is currently being read from the audio input stream and passed to the speech recognition engine.
See also ISpRecognizer::SetRecoState
The default recognizer state is SPRST_ACTIVE, which means the Speech Platform will activate the audio input stream only when at least one top-level rule is active.
To be notified when the recognizer state changes, rather than polling the state with ::GetRecoState, call ISpEventSource::SetInterest with SPEI_RECO_STATE
