Speech Recognition Capabilities Added to the DiaStar Server

Dialogic, a global provider of products and technologies for multimedia and signal processing, and LumenVox, a provider of speech recognition technologies, today announced the integration of the DiaStar Server release 2.1 and the LumenVox Speech Engine.

This integration brings the power and flexibility of the LumenVox ASR solution to Asterisk developers building voice and video applications with the DiaStar Server.

New and enhanced features that are now available through this integration include:

  • speech recognition for English, Spanish, and French;
  • real-time barge-in and speech recognition using the native Asterisk speech API;
  • support for speech industry standards, including SRGS grammars; and
  • compatibility with the LumenVox Speech Tuner to help test, troubleshoot, and improve speech recognition accuracy

These new features and enhancements continue to expand Asterisk developers' ability to use the DiaStar Server to create applications such as IVVR systems, video surveillance systems, video portals, mobile advertising and banking, multimedia social networking, and basic video call completion.

“This particular integration highlights many of the benefits of the open source development model and the client server architecture used with the DiaStar Server,” said Antony Martin, director of open-source engineering at Dialogic.  “We were able to leverage the previous work of LumenVox to integrate its products with Asterisk and get this integration working by only adding one simple function to DiaStar.”

"This solution brings even more value to users of LumenVox and Asterisk, whether they are existing customers or brand new users," said LumenVox President Edward Miller. "With DiaStar's seamless integration, it is now simple to build a voice and video IVR with world-class speech recognition."
