GSM 06.10 lossy speech compression
GSM provides telephone quality speech at a compressed rate of 13 Kbps. Compare this to the 64 KBps required by standard u-law and A-law codes. This site gives lots of info about the GSM format, along with free source code.
Digital Voice Systems Inc.
This company makes the AMBE-2000, a Vocoder chip that compresses speech down to a miniscule 4 Kbps. They have an additional product library of low bit-rate codes both in hardware and software.
comp.speech WWW site
This site contains the comp.speech FAQ, and also has links to their ftp site, which contains software for speech codecs.
