Amazon Web Services (AWS) Polly Speech Synthesis Plugin 1.11.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

• UniMRCP Server 1.7.0
• AWS SDK 1.9.181

The binaries are currently available for the following Linux distributions:

• Red Hat / CentOS 7 (unimrcp-polly-1.7.9-1.el7.x86_64.rpm)
• Red Hat / CentOS 8 (unimrcp-polly-1.7.9-1.el8.x86_64.rpm)

• Ubuntu 20.04 LTS (unimrcp-polly_1.7.9-focal_amd64.deb)

This release adds support for vendor-specific parameters specified as query parameters of xml:base in SSML. The release also fixes two issues.

The detailed list of changes introduced in this release follows.

New Features

• Allow the client to specify vendor-specific parameters via query parameters of the xml:base attribute in an SSML content.

Fixed Problems

• Fixed a race condition in processing of the STOP request and the SPEAK-COMPLETE event which could possibly cause a license depletion.
• If no voice engine is specified, set the voice engine in the speech synthesis request based on a selected voice. If the selected voice has both neural and standard voices, the first one in the list is used.

Configuration Parameters

• None.

Miscellaneous

• Updated the Usage Guide to reflect the changes introduced in this release.
