Google Dialogflow Plugin 1.11.0 Released

Google Dialogflow (GDF) Plugin 1.11.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.6.0
  • Google Dialogflow API v2
  • gRPC 1.7.3
  • Protobuf 3.4.0

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-gdf-1.6.4-1.el7.x86_64.rpm)
  • Ubuntu 16.04 LTS (unimrcp-gdf_1.6.4-xenial_amd64.deb)

This release addresses an interoperability issue with Cisco Broadworks media server. The release also fixes processing of vendor-specific parameters passed from GVP.

The detailed list of changes introduced in this release follows.
New Features
  • Allow to explicitly set the 'speech-complete' flag in SRGS XML grammars by means of a new meta tag 'speech-complete'. If the 'speech-complete' flag is not explicitly set in an SRGS XML grammar or a speech context, then the parameter defaults to 'false' for speech contexts used as a hint, and to 'true' otherwise.
Fixed Problems
  • Strip off double quotes from the values of vendor-specific parameters passed from GVP.
  • Make sure START-OF-INPUT is sent before sending RECOGNITION-COMPLETE with a completion cause set to 'no-match' or 'success'. Fixed interoperability with Cisco Broadworks media server.
  • When license server is in use, fixed processing of a connection hang-up event occurred when a license refresh request is being sent to the license server. This event could result in a few seconds-long outage of the service.
Configuration Parameters
  • None.
  • None.
