Abstract

Широкополосный языковой кодер, согласно одному варианту осуществления, включает в себя кодер диапазона низких частот и кодер диапазона высоких частот. Кодер диапазона низких частот выполнен с возможностью кодирования части широкополосного речевого сигнала диапазона низких частот в качестве набора параметров фильтра и кодированного сигнала возбуждения. Кодер диапазона высоких частот выполнен с возможностью вычисления значений параметров кодирования, задающих спектральную обводную и временную обводную части широкополосного речевого сигнала диапазона высоких частот. Временная огибающая основана на сигнале возбуж�
