  • Added support for the SDK properties InitialSilenceTimeout and EndSilenceStimeout.
Fixed Problems
  • Store submitted audio data into a wav file, when collection of utterances is enabled.
  • Reworked processing of STOP requests and input completion events.
  • If interim OnRecognizing events are not delivered, send START-OF-INPUT event upon processing OnRecognze event.
  • If an activity is not received within the specified activity timeout, complete recognition with no-match.
Configuration Parameters
