Abstract
A speech coder with three different bit rates adapted for the transmission of voice-over IP (VoIP) networks is presented. Continuously, a rate control device analyses the traffic congestion of the network and orders the speec h coder to switch among five operation modes if necessary. These modes incl ude mitigation techniques of packet losses.
