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 speech coder to switch among five operation modes if necessary. These modes include mitigation techniques of packet losses
