A new Asterisk UniMRCP Modules 1.3.1 release has been published and can be downloaded from the following location:

http://www.unimrcp.org/project/release-view/asterisk-modules-1-3-1

This is a minor release, which addresses certain issues. The application MRCPSynth() has been refactored to feed synthesized speech to Asterisk directly from the MPF callback. This allows to bypass unnecessary buffering in speech channel and deliver audio data to the Asterisk core as soon as possible. The new implementation of MRCPSynth() reflects the corresponding routine in SynthAndRecog(), which has proven to work flawlessly.

Please note that the corresponding binary packages for Ubuntu 14.04 LTS and RHEL/CentOS 6.5 are available to UniMRCP members for immediate download. The corresponding YUM and APT repositories have also been updated.

The released source package provides bare modules compatible with a large variety of Asterisk and UniMRCP versions, which you may choose from. In particular:

• Asterisk 1.6, 1.8, 10, 11, 12, and 13
• UniMRCP 1.1.0

The detailed list of changes introduced in this release follows.

1. Generic Speech Recognition API (res_speech_unimrcp.so)

2. Dialplan Applications (app_unimrcp.so)

 2.1. MRCPSynth()
