Events are added to call log files (special logs generated by the SpeechPort which contain audio for each decode and a host of other information). The call log files are generated in the responses folder located in the installation directory, under the Lang directory. Any number of events may be added. Call logging needs to be enabled prior to calling this function. Call logging can be enabled via LV_SRE_SetPropertyEx or in the client_property.conf file.
- int LV_SRE_AddEvent(HPORT hport, const char* EventName)
A handle to the speech port.
Any non-NULL, non-zero length string.
No errors; adding the event succeeded.
Either event logging is not enabled, EventName is NULL or of zero string length or you are trying to add EVENT_END_DECODE_SEQ event type without previously adding an EVENT_START_DECODE_SEQ type event.
The input hport is not a valid one.

// The below StreamCancel and LV_SRE_AddEvent functions are very important,
// and need to be called in the STREAM_STATUS_BARGE_IN_TIMEOUT state in this
// exact order for proper logging of the audio to the callsre file
//(proprietary audio log format).
// When StreamCancel is called, it is assumed that the audio is not going to
// be used for a decode and the data is packaged for logging if
// LV_SRE_AddEvent("NO_INPUT") is called.
// Adding the NO_INPUT event would allow you to listen to the logged audio
// through the SpeechTuner to debug the potential cause.
