Dans cet article, les conceptions de recherche simplifiées pour le livre de codes stochastique de prédiction linéaire excitée par code algébrique (ACELP) pour le codeur vocal ITU-T G.729D sont proposées. En utilisant deux cycles de recherche et en limitant la plage de recherche, la complexité informatique de l'approche proposée ne représente que 6.25 % de la méthode de recherche complète recommandée par G.729D. De plus, la complexité informatique de l'approche proposée ne représente que 59 % de la méthode globale de recherche de remplacement d'impulsions recommandée par G.729.1. Les résultats de simulation montrent que la qualité de la parole codée évaluée à l'aide des mesures de qualité subjective et objective standard présente une dégradation perceptuellement négligeable.

Abstract: In this paper, the simplified search designs for the stochastic codebook of algebraic code excited linear prediction (ACELP) for ITU-T G.729D speech coder are proposed. By using two search rounds and limiting the search range, the computational complexity of the proposed approach is only 6.25% of the full search method recommended by G.729D. In addition, the computational complexity of proposed approach is only 59% of the global pulse replacement search method recommended by G.729.1. Simulation results show that the coded speech quality evaluated by using the standard subjective and objective quality measurements is with perceptually negligible degradation.
