Abstract

UN SISTEMA DE COMPRESION DEL HABLA LLAMADO "TRANSFORM PREDICTIVE CODING", O TPC SUMINISTRA LA CODIFICACION DEL HABLA EN BANDA ANCHA DE 7 KHZ (MUESTREO DE 16 KHZ) EN UNA BANDA DE VELOCIDAD DE BITS DE OBJETIVO DE ENTRE 16 Y 32 KB/S (DE 1 A 2 BITS/MUESTRA). EL SISTEMA UTILIZA UNA PREDICCION A CORTO Y A LARGO PLAZO PARA ELIMINAR LA REDUNDANCIA EN EL HABLA. UN RESIDUAL DE PREDICCION SE TRANSFORMA Y SE CODIFICA EN EL DOMINANTE DE LA FRECUENCIA PARA SACAR PARTIDO DEL CONOCIMIENTO DE LA PERCEPCION AUDITIVA HUMANA. EL CODIFICADOR TPC UTILIZA SOLAMENTE CUANTIFICACION DE CIRCUITO ABIERTO Y POR LO TANTO TIENE UNA COMPLEJIDAD EMINENTEMENTE BAJA. LA CALIDAD DEL HABLA DE TPC ES ESENCIALMENTE TRANSPARENTE A 32 KB/S, MUY BUENA A 24 KB/S Y ACEPTABLE A 16 KB/S.
