Hi,
Our lab has been developing visual articulatory biofeedback using
ultrasound, EPG and acoustics for primarily clinical applications.
The acoustics side is very simple though - just using things like the
Kay Elemetrics acoustics package for feedback, mainly for intonation.
I recall that Rich McGowan has been developing some nice software for
visual feedback for liquids and vowels.. presented maybe two years
ago at the ASA...
Good luck,
Bryan
