Microsoft Azure Speech Synthesis (SS) Plugin 1.17.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.7.0
  • Microsoft Text-to-Speech REST API
  • Libevent 2.1.9
  • Rapidjson 1.1.0

The plugin supports the following endpoints:

  • Speech Service (regional)
  • Custom Speech Service (regional)
  • Speech Service (containerized)
  • Custom Speech Service (containerized)
  • Speech Service (private)
  • Custom Speech Service (private)

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-azure-ss-1.7.8-1.el7.x86_64.rpm)
  • Red Hat / CentOS 8 (unimrcp-azure-ss-1.7.8-1.el8.x86_64.rpm)
  • Ubuntu 18.04 LTS (unimrcp-azure-ss_1.7.8-bionic_amd64.deb)
  • Ubuntu 20.04 LTS (unimrcp-azure-ss_1.7.8-focal_amd64.deb)

This release improves memory usage when caching is enabled and provides a few fixes.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for playing out wav files via SPEAK requests referenced either by file:// or http://localhost/utterances URIs.
  • Set the SSL security level to 1 by default. This setting applies to the use of the license server on Ubuntu 20.04 and does not affect other supported distributions.
Fixed Problems
  • Fixed the status code on responses to SPEAK requests containing no body.
  • Improved memory usage while dealing with a large set of cache records by loading a cahce record from file on demand and releasing the memory after the cache record is no longer referenced.
  • Fixed a possible memory leak occurred when two file entries (waveforms and/or SDRs) have the same creation time, which is a very rare occasion not involved in the regular operation.
Configuration Parameters
  • Added a new attribute 'security-level' to the element 'license-server'.
Miscellaneous
  • Updated the Usage Guide to reflect the changes introduced in this release.
  • Do not log an intentional warning if the voice-gender loaded from configuration is an empty string (not specified).
  • Added new log statements related to the caching routine.

Thank you for using UniMRCP.
