Azure SR Plugin 1.13.0 Released

May 4 2020

Microsoft Azure Speech Recognition (SR) Plugin 1.13.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.7.0
  • 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-1.7.1-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-azure-sr_1.7.1-xenial_amd64.deb)
  • Ubuntu 18.04 LTS (unimrcp-azure-sr_1.7.1-bionic_amd64.deb)

This release addresses a production issue and allows to customize the way input and instance elements are populated.

The detailed list of changes introduced in this release follows.
New Features
  • Allow to customize the way input and instance elements are populated from JSON results received from the service. The behavior is configurable via new parameters 'input-token' and 'instance-token'.
  • The results format can now be specified per recognition request via the parameter 'results-format', which can be set either to 'standard' or 'json'.
Fixed Problems
  • The use of inter-result timeout, which is disabled by default, could cause a segfault under certain circumstances, when the timer is not properly stopped after the recognition completes. This issue was introduced in 1.12.0.
Configuration Parameters
  • Added new attributes 'input-token' and 'instance-token' to the element 'ws-streaming-recognition'. The attributes accept one of the following values 'Lexical', 'ITN', 'MaskedITN', 'Display'.
Miscellaneous
  • Updated the Usage Guide to reflect the changes introduced in this release.
