When transmitting real-time audio information through packet-switched networks, some packets are lost and this reflects directly on the perceived speech quality of the reproduced signal. Various codecs can be used and the perceived quality varies in a complex manner depending on the codec as well as statistical parameters of packet loss. Automatic optimization of communication channel and achieving good speech quality and intelligibility at a fixed maximum bitrate is not a simple goal and is achieved using models of human vocal tract and elements of subjective speech quality judgement as well as communication channel and packet loss modelling.
