Abstract
EN UN PROCESADOR DE VOZ, COMO PUEDE SER UN RECONOCEDOR DE VOZ, EL PROBLEMA DE LA DISTORSION DE LAS CARACTERISTICAS EXTRAIDAS, PROVOCADO POR LA ADAPTACION DEL CONTROL AUTOMATICO DE GANANCIA DE LA ENTRADA (AGC) DURANTE LA EXTRACCION, SE RESUELVE ALMACENANDO EL COEFICIENTE DE GANANCIA AGC JUNTO CON EL NIVEL ENERGETICO DE CADA CARACTERISTICA EXTRAIDA. AL FINAL DEL MUESTREO, LOS COEFICIENTES DE GANANCIA ALMACENADOS SE IGUALAN AL COEFICIENTE MINIMO ALMACENADO, AJUSTANDOSE ACORDEMENTE LOS NIVELES DE ENERGIA ASOCIADOS. EL CIRCUITO AGC PUEDE CONSTAR DE UN ATENUADOR CONMUTADO DIGITALMENTE BAJO CONTROL DE UN MICROPROCESADOR QUE EFECTUA EL RECONOCIMIENTO DE LA VOZ.
