Morning Simon,
Yes, were using Sphinx, but not on our Asterisk server. Were using
Sphinx4 to take recorded calls, scan for keywords, then upon identifying
keywords using a second vocabulary to do further analysis of the call in
proximity to the keyword.
Now if this sounds wacky, the purpose is to identify activity and to
remove personal information from a recorded conversation ( which is what
we do ). For example, if we recorded a hotel agent, we looking for a
hotel reservation. So we are scanning the audio to see if a reservation
was made (keywords: confirmation number, credit card, amex, etc....) and
if so replace the credit card number number, and other identifying data
(second keyword dictionary: digits only) with a tone of equal time
duration so as to maintain the call time integrity.
Is pretty cool stuff, but pretty resource intensive and a very steep
learning curve. I've just glad I have a good java programmer that also
gets it.

And wouldn't speech-to-text of your voicemail -> email be a cool feature?
Or maybe an email -> voicemail gateway... Hmmm.
