A New Government Standard 2400 bps Speech Coder

The US Goverment is seeking a new 2400 bps speech coding algorithm. Researchers, contractors, and institutions are invited to participate in a cooperative effort to develop this standard. It is our hope that this standard will significantly enhance global secure voice communications, offering high quality coding at 2400 bps.
