[Freeswitch-users] VoiceMail transcription

[Kirk Bateman]

Not sure, but they do certainly have a reasonably large server farm for
doing processing :)

I note that sphinx4 I believe has a java example for doing dictation
transcription from an audio file (saw something on a sphinx forum or mailing
list while trawling the net).

I'm still investigating modifications to use pocketsphinx.

Regards

Kirk
