摘要

A speech decoding device for decoding a coded speech serial, in which the speech decoding device comprises: bit stream separation means for separating a bit stream that includes the coded speech serial in a coded bit stream , Spectral Band Replication (SBR) supplementary information and temporary envelope supplementary information, the bit stream received from outside the speech decoding device: central decoding means for decoding the encoded bit stream separated by the separation means bit stream to obtain a low frequency component; frequency transformation means for transforming the low frequency component obtained by the central decoding means into a frequency domain; high frequency generating means for generating a high frequency component by copying the low frequency component transformed in the frequency domain by means of frequency transformation from a low frequency band to a high frequency band; high frequency adjustment means to adjust the high frequency component generated by the high frequency generation means to generate a high frequency component adjusted, in accordance with the supplementary information of SBR;
