Hi Alfred, There is a research project by Carnegie Mellon University (CMU) on a very versatile Speech Recognition Software. Its Sphinx http://cmusphinx.sourceforge.net/html/cmusphinx.php . This application is in raw state and the Version 2 of sphinx could be integrated with Asterisk. Festival (Text to Speech application) that is widely used in asterisk is by CMU. Refer http://www.voip-info.org/wiki-Sphinx . I hope this gives a pretty good start.
Sphinx needs to be trained with a language model. But since your requirement is just names it should not be complicated. Also have a look at http://www.speech.cs.cmu.edu/Communicator/ . Something I have not looked into much (and I don't know if it has anything to do with Asterisk). I hope this helps. Regards, Kurian Thayil.
