Abstract

The algebraic code excited linear prediction (ACELP) structure has been adopted by many speech coding standards because of its high speech quality. With analysis-by-synthesis optimizations, the ACELP speech coder can provide an efficient coding technique for the linear predicted residuals. This paper introduces the unified pulse-replacement (UPR) algorithm again and evaluates its performance for the 3GPP-AMR 12.2k speech coder. Simulation results show that the UPR algorithm can reduce the computational complexity of 3GPP-AMR speech coder with an imperceptible degradation of speech quality.
