Abstract :
Robust and flexible speech codecs are more and more required by speech communication over unreliable channels such as Internet. In this paper, a novel multiple description (MD) sinusoidal speech codec is proposed. This codec is based on sinusoidal and equivalent rectangular bands (ERB) noise model. It can provide relatively high transmission reliability as well as good coding efficiency. And the lost packet doesn´t affect the state recovery of this state-less MD codec. Therefore it is very suitable to unreliable and band limited channel such as Internet
