"With this integration with trixbox 2.0, we are bringing point-and-click installation and management of LumenVox speech recognition to the trixbox community. One of our goals as a company is to popularize the use of speech recognition technology across a variety of markets, and the trixbox 2.0 platform and its users are clearly in line with that mission," said Gerd Graumann, director of business development at LumenVox.

The LumenVox Speech Engine is the core speech recognition technology that handles the recognition of words and phrases. Lumenvox could be purchased fro the original Asterisk developer, Digium. Depending on your grammar requirements etc, you can purchase a version best fits your needs.
