The plugin is based on the following components:

  • UniMRCP Server 1.6.0
  • Yandex SpeechKit Speech to Text API v2
  • gRPC 1.7.3
  • Protobuf 3.4.0
  • Libevent 2.1.9

The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-yandex-sr-1.6.2-1.el7.x86_64.rpm)

  • Ubuntu 18.04 LTS (unimrcp-yandex-sr_1.6.2-bionic_amd64.deb)

This release adds support for HTTP proxy, introduces binaries for Ubuntu 18.04 LTS and fixes a few problems.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for HTTP proxy.
Fixed Problems
  • 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.
