Abstract

L'invention concerne un système (130) permettant d'améliorer un signal en fréquence vocale dans un réseau de télécommunication (138). Ce système (130) comprend un moyenneur de puissance (18) pour déterminer la puissance moyenne du signal vocal, ainsi qu'un égaliseur (132) pour atténuer une partie prédéterminée du signal vocal, et un dispositif d'étalement de sortie (134) pour étaler le signal vocal égalisé selon un facteur scalaire. Le système de l'invention (130) comprend en outre un dispositif d'amélioration automatique de gain (136) pour appliquer un facteur de gain automatique au signal vocal égalisé, dans lequel le facteur de gain dépend de la puissance moyenne du signal vocal d'entrée.
