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

[Alfred Monticello]

Thanks. This has been useful, I've been toying with Sphinx4 but haven't gotten very far with it yet. Took a while to get my environment set up to compile all the java sources.. should have downloaded the binary distro...:-)

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.

I wouldn't have a database to compare names to, each one would essentially be unique and unknown. It's sounding like this idea may be not possible...What high end options are available? I read about lumenvox, but I believe that compares to a known list of names (such as a directory, or Yes No, Digits, etc)....

Hum...

There are solutions ranging from free to
many thousands of dollars, with effectiveness ranging from nearly worthless to
almost pretty good.
 
A lot depends on your application. 
 
The most successful application would
match an utterance from a known speaker to a known list of a couple dozen
names. For example, if I say "Alfred Monticello," the application
can easily distinguish this from other list entries such as "Don Kelly"
and "Robert Smith."
 
The least successful would attempt to
convert an utterance from an unknown speaker to text (which is what your
inquiry implies). Even if it clearly "understands" the speaker, the
result could easily be "Alphret Mahntichelo."

I'm interested in taking a persons spoken recorded name (First, Last) and
converting the two spoken words to text. Is there any solutions out there that
would make this possible?
