New Features
  • Allow query parameters of the Azure WebSocket Speech API be transparently specified by the client via vendor-specific parameters. The parameter name must be prefixed with 'azure.stt.' For example:azure.stt.initialSilenceTimeoutMs=1000.
  • Added the request id set in the Websocket messages to the RDRs.
Fixed Problems
  • Fixed a possible segfault, which could be encountered when a response to the access token revalidation request arrives late, after a pending RECOGNIZE request is stopped and the associated MRCP session is closed.
Configuration Parameters
  • None.
  • Updated the Usage Guide to reflect the changes introduced in this release.
