Bing SR Plugin 1.3.0 Released

Microsoft Bing Speech Recognition (BingSR) Plugin 1.3.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.5.0
  • Microsoft Speech WebSocket Protocol
  • Libevent 2.1.8
  • Rapidjson 1.1.0

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7
  • Ubuntu 16.04 LTS

This release adds support for resampling, which allows to transform audio data in incoming RTP stream from 8 kHz to 16 kHz.

Also, when both the speech and DTMF detectors are activated, the DTMF detector remains active until a first interim result of speech transcription becomes available. In order to enable this behavior, the configuration parameter 'start-of-input' must be set to 'service-originated'.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for resampling from 8 kHz to 16 kHz.
Fixed Problems
  • None.
Configuration Parameters
  • Changed the default value of the attribute 'speech-incomplete-timeout' from 1000 to 3000.
  • Improved the speech and DTMF input detector.
  • Updated the Usage Guide accordingly.

Thank you for using UniMRCP.
