Abstract
The coding algorithm widely recognised as offering the best prospects for delivering toll-quality speech at very low bit rates is called CELP (codebook-excited linear prediction) coding. The CELP codec by Delphi Systems operates in real time, uses a standard digital signal processing chip, and encodes speech at 4.8 and 6.5 kbit/s. The use of this speech compression codec (SCC) is also discussed
