Abstract

In this paper, a novel voicing-driven adaptive packet loss recovery algorithm is proposed to lessen the possible voice degradation and error propagation for analysis-by-synthesis speech coders in Internet applications. After voicing classification, we adaptively adopt random noise generation, multiresolution excitation generation, or pulse tracking procedure to recover the lost packets. By applying the algorithm to the G.723.1 coder, simulation results show that the proposed algorithm is superior to the recovery algorithm embedded in the G.723.1 standard through the subjective evaluation.
