Azure SR Plugin 1.15.0 Released

[Arsen Chaloyan]

Microsoft Azure Speech Recognition (SR) Plugin 1.15.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

• UniMRCP Server 1.7.0
• Microsoft Speech WebSocket Protocol
• Libevent 2.1.9
• Rapidjson 1.1.0

The plugin supports the following endpoints:

• Speech Service (regional)
• Custom Speech Service (regional)
• Speech Service (containerized)
• Custom Speech Service (containerized)

The binaries are currently available for the following Linux distributions:

• Red Hat / CentOS 7 (unimrcp-azure-sr-1.7.5-1.el7.x86_64.rpm)
• Ubuntu 16.04 LTS (unimrcp-azure-sr_1.7.5-xenial_amd64.deb)
• Ubuntu 18.04 LTS (unimrcp-azure-sr_1.7.5-bionic_amd64.deb)

This release adds support for dictation mode and also provides a few fixes and enhancements.

The detailed list of changes introduced in this release follows.

New Features

• Added support for dictation mode (continuous speech transcription) in addition to interactive mode (single utterance).
  
• When a STOP request is received, close the WS connection straightaway without waiting for normal completion. This change also allows to unconditionally release the associated license.
• If a WS close message is received from the service or the WS connection is closed by the service, a new connection is created on processing of the next RECOGNIZE request.

Fixed Problems

• When the service unexpectedly sends a WS close message with a reason "Instance is shutting down", the next RECOGNIZE request could fail by possibly causing a license depletion.

Configuration Parameters

• Added new attribute 'single-utterance' to the element 'ws-streaming-recognition'.
• Changed default values of 'speech-incomplete-timeout' from 3000 msec to 15000 msec and 'input-timeout' from 10000 msec to 30000 msec.

Miscellaneous

• Updated the Usage Guide to reflect the changes introduced in this release.
