This release is built against the latest NVIDIA Riva Speech Skills 2.15.0. The release provides a few minor fixes and enhancements.

The detailed list of changes introduced in this release follows.
New Features
  • None.
Fixed Problems
  • Fixed processing of max-file-age, which can optionally be set for waveforms, to properly remove file entries when max-file-age is reached.
  • Fixed a race condition issue in processing SPEAK -> STOP -> SPEAK requests. The problem is encountered when the first SPEAK request is placed via HTTP to the service endpoint and stopped immediately, while the second SPEAK request is served from the local cache.
  • Make sure special characters are always escaped in SSML.
Configuration Parameters
  • None.
  • Updated the NVIDIA Riva Speech Skills from 2.0.0 to 2.15.0.
