The release provides a few fixes and improvements in the existing functionality.

The detailed list of changes introduced in this release follows.
New Features
  • Made HTTP request timeout configurable.
  • Allow voice name be also specified via Vendor-Specific-Parameters using the 'voice-name' token.
Fixed Problems
  • Fixed a possible memory leak on processing the second and consecutive SPEAK requests in the scope of a single MRCP session.
  • Fixed a possible segfault encountered on the MRCP session termination when a response to the ongoing speech synthesis request is delayed.
  • Fixed a race condition in processing of the STOP request and the SPECH-COMPLETE event which could possibly cause a license depletion.
  • Fixed a possible segfault on processing the header field Logging-Tag having an empty [no] value.
Configuration Parameters
  • Added new attributes 'request-timeout' and 'auth-request-timeout' to the element 'synth-settings'. The attributes default to 30 seconds.
  • Log not only status code but also status text extracted from received HTTP responses.
