Abstract

En un descodificador del habla el cual experimenta borrado o supresion de cuadro, se incrementa el retraso de paso asociado con el primero de una serie de cuadros borrados consecutivos. El valor incrementado se utiliza como el retraso de paso para el segundo de los cuadros borrados consecutivos. El retraso de paso asociado con el primero de los cuadros borrados consecutivos puede corresponder a la ultima informacion de retraso de paso recibida correctamente desde un codificador del habla (asociado con un cuadro no borrado), o en sí mismo puede ser el resultado de un incremento añadido a un valor fijo previo de retraso del paso (asociado con un cuadro borrado previo fijo).
