Azure SR Plugin 1.10.0 Released

Microsoft Azure Speech Recognition (SR) Plugin 1.10.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.6.0
  • Microsoft Speech WebSocket Protocol
  • Libevent 2.1.9
  • Rapidjson 1.1.0

The plugin supports the following endpoints:

  • Speech Service
  • Bing Speech

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-azure-sr-1.6.4-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-azure-sr_1.6.4-xenial_amd64.deb)
  • Ubuntu 18.04 LTS (unimrcp-azure-sr_1.6.4-bionic_amd64.deb)

This is a release of Microsoft Azure SR plugin, the successor of Microsoft Bing SR plugin. The main purpose of this change is not to use the name Bing, which is associated with the speech service being decommissioned by Microsoft in October, 2019. The Azure plugin derives all the version and revision numbers from the outdated Bing plugin. While there are no functional changes introduced in this release, all the related artifacts, including the plugin name, configuration and status file names, documentation and webpages, have been renamed or replaced to reflect the change.

To facilitate migration of existing UniMRCP server installations from using Bing to Azure plugins, helper shell scripts are provided for Red Hat and Debian-based distributions in the following archive file.

Thank you for using UniMRCP.
