Google SS Plugin 1.5.0 Released

Google Speech Synthesis (GSS) Plugin 1.5.0 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-1.6.2-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-gss_1.6.2-xenial_amd64.deb)

This release addresses an interoperability issue with AEP and also introduces the ability to split SSML content into multiple segments.

The detailed list of changes introduced in this release follows.
New Features
  • If 'bypass-ssml' is set to false, and multiple voice elements are present in supplied SSML, then the content is split into multiple segments per voice element. Each segment is sent to the service in a sequential order. Streaming to the client is started as soon as synthesis of the first segment is complete.
Fixed Problems
  • If a SPEAK request is stopped when synthesized speech is being streamed to the client, then the remaining part of the synthesized speech could be left in media buffer and be streamed on a consecutive SPEAK request received in the scope of the same MRCP session. Fixed interoperability with AEP.
  • When license server is in use, fixed processing of a connection hang-up event occurred when a license refresh request is being sent to the license server. This event could result in a few seconds-long outage of the service.
Configuration Parameters
  • None.
  • None.
