GoVivace SR Plugin 1.2.0 Released


GoVivace Speech Recognition (SR) Plugin 1.2.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.6.0
  • GoVivace WebSocket Protocol
  • Libevent 2.1.9
  • Rapidjson 1.1.0

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-govivace-sr-1.6.3-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-govivace-sr_1.6.3-xenial_amd64.deb)
  • Ubuntu 18.04 LTS (unimrcp-govivace-sr_1.6.3-bionic_amd64.deb)

This release allows to reference a GoVivace server based on the name of built-in grammars. The release also introduces supplementary features and fixes a few minor problems.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for referencing a GoVivace server based on the name of built-in grammars.
  • Added support for certain vendor-specific parameters, including 'speech-start-timeout'. See section 4.7 in the Usage Guide.
  • Added support for the content type 'text/grammar-ref-list'.
  • Added support for HTTP proxy in communication with license servers available as a service.
  • 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
  • Compose the header field Waveform-URI based on the protocol version. Before, the format defined in MRCPv2 was used unconditionally.
  • Signal input completion and close the connection forcefully without waiting for a response if the recognition request is stopped and/or a response is no longer needed.
Configuration Parameters
  • Added new attributes 'http-proxy-address' and 'http-proxy-port' to the element 'license-server'.
  • Added a new attribute 'use-logging-tag' to the elements 'utterance-manager' and 'rdr-manager'.
Miscellaneous
  • Added a new log statement "Received WS Close" containing status code and reason of closure of the WebSocket close frame.
  • Added connection identifier to statements logged on each message received.
  • Updated the Usage Guide to reflect the changes introduced in this release.
