AWS Polly Plugin 1.10.0 Released

[Arsen Chaloyan]

Amazon Web Services (AWS) Polly Speech Synthesis Plugin 1.10.0 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-1.7.7-1.el7.x86_64.rpm)
• Red Hat / CentOS 8 (unimrcp-polly-1.7.7-1.el8.x86_64.rpm)
• Ubuntu 18.04 LTS (unimrcp-polly_1.7.7-bionic_amd64.deb)
• Ubuntu 20.04 LTS (unimrcp-polly_1.7.7-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

• Allow voice name and gender be also specified via Vendor-Specific-Parameters using voice-name and voice-gender tokens correspondingly.
• Output license and maintenance expiration dates to status files, if/when applicable.
• 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

• Improved memory usage while dealing with a large set of cache records by loading a cache 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.
• Added new log statements related to the caching routine.
