Abstract
PARA EJECUTAR LA CODIFICACION DE PREDICCION LINEAR DE CODIGO DE EXCITACION (CELP), POR EJEMPLO, LOS PARAMETROS-(ALFA) SON EXTRAIDOS DESDE LA ENTRADA DE SEÑAL DE VOZ POR UN CIRCUITO DE ANALISIS (12) DE CODIFICACION DE PREDICCION LINEAR. LOS PARAMETROS-(ALFA) SON CONVERTIDOS DESPUES POR UN CIRCUITO DE CONVERSION (13) DE PARAMETROS-(ALFA) A LSP EN PARAMETROS DE PAR ESPECTRAL LINEAL (LSP), Y UN VECTOR DE ESTOS PARAMETROS DE PAR ESPECTRAL LINEAL (LSP) ES CUANTIFICADO POR UN CUANTIFICADOR (14). EL INTERRUPTOR DE CAMBIO (16) ES CONTROLADO DEPENDIENDO DEL VALOR DE PULSACION DETECTADO POR UN CIRCUITO (22) DE DETECCION DE TONOS PARA SELECCION Y UTILIZACION DE UNO DE LOS LIBROS DE CODIGOS 15M PARA VOCES MASCULINAS Y EL LIBRO DE CODIGOS 15F PARA VOCES FEMENINAS, PARA MEJORAR LAS CARACTERISTICAS DE CUANTIFICADO SIN INCREMENTAR EL PROMEDIO DE TRANSMISION DE BITS.
