Recognizer STOP

Reference Number: AA-01659 Views: 2030 0 Rating/ Voters

The STOP method from the client to the server tells the recognizer resource to stop recognition if one is active.  If a RECOGNIZE request is active and the STOP request successfully terminated it, then the response header contains an active-request-id-list header field containing the request-id of the RECOGNIZE request that was terminated.  In this case, no RECOGNITION-COMPLETE event will be sent for the terminated request.  If there was no recognition active, then the response will not contain an active-request-id-list header field.  Either way,method the response will contain a status of 200(Success).
