Azure Bot Plugin 1.0.0 Released

Microsoft Azure Bot Service (ABS) Plugin 1.0.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

  • UniMRCP Server 1.7.0
  • Azure Speech SDK 1.11.0

The binaries are currently available for the following Linux distributions:

  • Ubuntu 16.04 LTS (unimrcp-azure-bot_1.7.0-xenial_amd64.deb)
  • Ubuntu 18.04 LTS (unimrcp-azure-bot_1.7.0-bionic_amd64.deb)

IVR platforms can now utilize conversational interfaces provided by Microsoft Azure via UniMRCP Server.

The new plugin is intended to support the following two back-ends provided by Microsoft Azure for development of conversational interfaces.


With the current release, the plugin allows to perform streaming speech transcription based on intents specified in a LUIS model. With this mode of operation, the speech application ultimately controls the dialog flow by specifying a LUIS model and a set of intents to be applied to each recognition request. The speech application may reference multiple LUIS models in the scope of a single MRCP session.

Bot Service

In a follow-up release, the plugin will support interactions with Bot Service via Direct Line Speech. The dialog flow is controlled by a bot in this case. The bot returns a detected intent and also the next prompt to be played to the caller.


For more information on LUIS and Bot Service, start with basic concepts.

For installation, configuration and usage instructions, follow the guides available on a new Azure Bot plugin page.


Please note this is a commercial module. Everyone is welcome to start evaluation by requesting a trial license.

Thank you for using UniMRCP.
