FIELD: physics.
SUBSTANCE: speech decoder includes a demultiplexing unit, a low-pass band decoding unit, a frequency band filter bank unit, an encoded sequence analysis unit, an encoded sequence decoding/dequantization unit, a high-frequency band generating unit, calculating time envelopes of the high frequency band using time envelope information and a plurality of temporal envelopes of the low frequency band, a temporal envelope correction unit that corrects the temporal envelope of the high frequency portion of the low frequency band, which computes the time envelope of the low frequency band, bands using temporal envelopes obtained by the temporal envelope calculation unit and a ban unit frequency filter synthesis filters.
EFFECT: decrease in the leading and lagging echo.
