[asterisk-users] Ideas on how to convert spoken name to text (orwav to text)..speech recognition software?

[Kurian Thayil]

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.
