Google SS Plugin 1.4.0 Released

February 21 2019

Google Speech Synthesis (GSS) Plugin 1.4.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.6.0
  • Google Text-to-Speech API v1
  • gRPC 1.7.3
  • Protobuf 3.4.0

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-gss-1.6.1-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-gss_1.6.1-xenial_amd64.deb)

This release fixes the use of annual node-bound licenses, and an issue in interoperability with Genesys PureConnect. There are other minor improvements introduced in the release.

The detailed list of changes introduced in this release follows.
New Features
  • If enabled from configuration, SSML content passed to the service is normalized to conform to the subset of SSML supported by Google Text-to-Speech API.
  • The HTTP proxy URI, if used, can now be specified from configuration instead of an environment variable.
  • Set an alarm in the status file if the license server is not reachable for a certain period of time, but the service is not yet affected. Clear the alarm as soon as the license server becomes available. See Section 6.2 in the Usage Guide.
Fixed Problems
  • Added support for optional parameters set in the header field Content-Type [application/ssml+xml; charset=utf-8]. Fixed interoperability with Genesys PureConnect.
  • If an annual node-bound license is used, the expiration time of the license could be provisioned incorrectly, requiring a restart of the service in order to continue normal operation.
Configuration Parameters
  • Added a new attribute 'normalize-ssml' to the element 'synth-settings'.
  • Added a new attribute 'http-proxy' to the element 'synth-settings'.
Miscellaneous
  • Changed log level of statements made for setting voice parameters from Debug to Info.
  • Updated the Usage Guide to reflect the changes introduced in this release.
