Remarks

The SPFEI_FLAGCHECK macro retrieves the flags that must always be included in any event interest. SAPI uses the SPFEI_FLAGCHECK macro to help developers avoid mistakes by using event interest related methods (see ISpEventSource::SetInterest and ISpRecoContext::SetVoicePurgeEvent) with the actual enumeration instead of the SPFEI() macro.

Example

Here is an example of the SPFEI macro used to set SR event interest

  
hr = g_cpRecoCtxt->SetInterest(SPFEI(SPEI_RECOGNITION), SPFEI(SPEI_RECOGNITION));

Here is an example of the SPFEI_ALL_SR_EVENTS macro used to set SR event interest in all events. Note this is an example and not recommended practice.

  
hr = g_cpRecoCtxt->SetInterest(SPFEI_ALL_SR_EVENTS, SPFEI_ALL_SR_EVENTS);
