Research of an improved packet loss compensation algorithm in VoIP

This paper mainly introduces several packet loss processing technology used for VoIP network voice calls application, to reduce the phonetic distortion caused by the package loss based on VoIP network, putting forward a scheme based on improved interlace technology and media-related forward error correction technology combining Lagrangian interpolation compensation algorithm, which can reduce the phonetic distortion caused by the package loss based on VoIP network, this scheme improves resistanced continuous frame loss ability and solves dropped frames recovery and compensation, thereby improve the VoIP speech quality.
