Azure SR Plugin 1.12.0 Released


Microsoft Azure Speech Recognition (SR) Plugin 1.12.0 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-1.6.6-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-azure-sr_1.6.6-xenial_amd64.deb)
  • Ubuntu 18.04 LTS (unimrcp-azure-sr_1.6.6-bionic_amd64.deb)

This release addresses a few production issues and introduces supplementary features and enhancements to the existing functionality.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for inter-result timeout. If the specified timeout is elapsed, input is considered complete. The timeout defaults to 0 (disabled) and can be overridden per recognition request.
  • If the configuration parameter 'use-logging-tag' is set to 'true', the header field Logging-Tag, if specified, is used as a suffix while composing file names of utterances and RDRs.
Fixed Problems
  • Fixed a race condition in asynchronous processing of initiation of a new turn and termination of the current turn, occurred when audio data for the new turn becomes available earlier than 'turn.end' event is received for the turn being terminated.
  • Fixed a race condition, occurred when speech completes earlier than a WebSocket connection to the service is fully established.
Configuration Parameters
  • Added a new attribute 'inter-result-timeout' to the element 'ws-streaming-recognition'.
  • Added a new attribute 'use-logging-tag' to the elements 'utterance-manager' and 'rdr-manager'.
Miscellaneous
  • Changed the log level of statement "Unknown Parameter" from WARNING to DEBUG.
  • Updated the Usage Guide to reflect the changes introduced in this release.
