I have an Ada 83 whiteboard program that does LPC speech compression.
It's pretty straightforward. If you're interested in particular in
encrypted speech, look in comp.speech for references to "Nautilus",
which does very simple compression (essentially, it decides between
two canned sets of LPC-2 parameters and also transmits a single bit
of error/sampel, as I recall) and encrypts the speech in real time.
It was mentioned between 6 months and 1 year ago, I think. Phil
Zimmerman, of PGP fame, is reportedly incorporating and one of the
products will be speech encryption - I don't know if that derives
from Nautilus.
