FIELD: data processing.
SUBSTANCE: invention relates to means for encoding and decoding speech. Speech decoder includes a demultiplexing unit, a low frequency band decoding unit, a frequency band split filter bank unit, an encoded sequence analysis unit, a coded sequence decoding/de-quantizing unit, a high frequency band generation unit, low frequency band time envelope calculating units, which obtain a plurality of low frequency band envelopes, time envelope calculating unit that calculates temporal envelopes of high frequency band using time envelope information and plurality of temporal envelopes of low frequency band, temporal envelope correction unit that corrects time envelope of high frequency band components using time envelopes obtained by temporal envelope calculating unit and band filter bank unit.
EFFECT: technical result consists in reducing leading and lagging echo.
