Google SR Plugin 1.8.0 Released


Google Speech Recognition (GSR) Plugin 1.8.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.5.0
  • Google Speech API v1
  • 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 interoperability with Cisco Unified Customer Voice Portal (CVP).

The release also fixes a few major issues encountered under certain circumstances and introduced in the previous 1.7.0 version of the plugin.

Everyone is encouraged to upgrade.

The detailed list of changes introduced in this release follows.
New Features
  • Made the name of the built-in speech transcription grammar configurable, which defaults to 'transcribe'.
  • Allow 'builtin:speech/$name' and 'builtin:grammar/$name' to be used interchangeably.
  • Accept SRGS speech grammars without processing of any rules defined in the grammar.
Fixed Problems
  • When the configuration parameter 'start-of-input' is set to 'service-originated', then no-input timer might have not been stopped upon start of speech. This issue was introduced in 1.7.0 release.
  • When the configuration parameter 'start-of-input' is set to 'internal', then under certain circumstances, this could have caused license depletion. This issue was introduced in 1.7.0 release.
  • Escaped XML control characters which may appear in transcription results. For instance, "AT&T" will be replaced with "AT&T".
Configuration Parameters
  • Added a new attribute 'skip-unsupported-grammars', which defaults to 'true'.
  • Added a new attribute 'transcription-grammar', which defaults to 'transcribe'.
Miscellaneous
  • Changed grammar referencing routine to be, by default, tolerant to malformed and not supported grammars.
