Hi Jeff,
   The subjective speech quality of (a correctly implemented) 4800bps
CELP speech compression system is very impressive and is quite suitable
for telephone-quality speech.

   My company, Analogical Systems, has implemented a U.S.F.S 1016 CELP
vocoder based upon a single 27MHz Motorola DSP56001 (the analyzer
searches the entire 512 stochastic vector codebook in real time).
The DSP56001 source and/or object code is available for licensing.

   Demonstration systems are also available, based upon Ariel Corp's
PC-56 or PC-56D boards. A complete demonstration system (including the
Ariel PC-56 board) is available from Analogical Systems for only $595.
This would allow you to assess the speech quality for yourself.

   Feel free to contact me directly at Analogical Systems, 415-323-3232.

Best Regards,
Cole Erskine
