[MV] Voice Recognition Tech Question

[revDAVE]

I have a question regarding voice-recognition technology. As I understand
it, ViaVoice and iListen, and other programs use the type of technology
where you must "program a voice model" by reading some text into the
application, so it can " learn " your voice...

Question: but I am curious what kind of voice to speech technology is being
used by large corporations - such as those customer phone services - where
the customer " speaks the answers"  to computer questions over the phone?
Obviously there is some other kind of technology going here - since it is
universally /  generically understanding millions of "un-programed" voices.
Does anybody know what kind of technology is being used here?
