摘要
A speech decoder (1) includes a demultiplexing unit (1a), a low frequency band decoding unit (1b), a band splitting filter bank unit (1c), a coded sequence analysis unit (1d), a coded sequence decoding / dequantization unit (1e), a high frequency band generation unit (1h), low frequency band time envelope calculation units (1f 1 to 1f n ) that acquire a plurality of low frequency band time envelopes, a time envelope calculation unit (1g) that calculates high frequency band time envelopes using time envelope information and the plurality of low frequency band time envelopes, a time envelope adjustment unit (1i) that adjusts the time envelope of high frequency band components using the time envelopes obtained by the time envelope calculation unit (1g), and a band synthesis filter bank unit (1j).
