Google Dialogflow Plugin 1.2.0 Released

Google Dialogflow (GDF) Plugin 1.2.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.5.0
  • Google DIalogflow API v2beta1
  • gRPC 1.7.3
  • Protobuf 3.4.0

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7
  • Ubuntu 16.04 LTS

This release addresses a few possible race condition issues and adds support for Speech-Incomplete-Timeout.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for the MRCP header field Speech-Incomplete-Timeout, which is observed only when the attribute 'interim-results' is set to 'true'.
Fixed Problems
  • Fixed a possible segfault when response to gRPC stream creation arrives after no-input timeout is elapsed.
  • Always wait for reading to complete and only then finish the gRPC streaming.
  • If project-id is missing, respond with a completion cause ERROR instead of GRAM_LOAD_FAILURE.
Configuration Parameters
  • Added a new attribute 'speech-incomplete-timeout' to the element 'speech-dtmf-input-detector', which is set to 1000 msec by default.
  • Changed the default value of the configuration parameter 'vad-mode' from 1 to 2.
  • Added session identifier to all the statements logged by speech input detector.
