摘要：
In this paper we propose a low-delay packet loss concealment scheme for packetized voice communication. The scheme operates on the source-filter components of the speech signal and is to be implemented in receivers of a potential system. A sinusoidal model of successfully received speech is utilized to recover lost frames using both extrapolation and interpolation techniques. Informal subjective testing show promising results; recovered packet losses axe often inaudible to a listener.
