Google Dialogflow Plugin 1.19.0 Released

August 9 2021

Google Dialogflow (GDF) Plugin 1.19.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.7.0
  • Google APIs 1.5.0
  • gRPC 1.30.3
  • Protobuf 3.12.2

The plugin supports the following Dialogflow API versions:

  • v2
  • v2beta1
  • v3
  • v3beta1

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-gdf-1.7.6-1.el7.x86_64.rpm)
  • Red Hat / CentOS 8 (unimrcp-gdf-1.7.6-1.el8.x86_64.rpm)
  • Ubuntu 18.04 LTS (unimrcp-gdf_1.7.6-bionic_amd64.deb)
  • Ubuntu 20.04 LTS (unimrcp-gdf_1.7.6-focal_amd64.deb)

This release is built against a newer version of Google APIs and a patched version of the gRPC library. The release introduces full support of regional ES (v2beta1) and CX (v3, v3beta1) agents. An extended set of features is now supported for CX agents.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for additional input query parameters introduced for the CX agents such as 'parameters', 'currentPage', 'disableWebhook', 'analyzeQueryTextSentiment', 'webhookHeaders', 'flowVersions'.
  • In addition to triggering an intent, added support for triggering an event and an input text available for the CX agents only.
  • Allow user applications to pass QueryParameters with an event grammar in a similar manner employed with speech and DTMF grammars.
Fixed Problems
  • Set the audience on requests sent to regional service endpoints.
  • When no intent is available in results received from a CX agent, pass through the received data structure to the user application. The recognition completion cause is set to success instead of no-match in such a case with the actual cause being set in the data structure received from Dialogflow.
Configuration Parameters
  • None.
Miscellaneous
  • Patched the gRPC library to allow the user application to set audience/scope on requests sent to Google.
  • Upgraded Google APIs from unigoogleapis-1.4.0 to unigoogleapis-1.5.0.
  • Updated the Usage Guide to reflect the changes introduced in this release.
