FIELD: physics.
SUBSTANCE: invention relates to the computer equipment. Speech decoder comprises a demultiplexing means; low-frequency band decoding means; frequency conversion means; high-frequency band coded sequence analysing means; decoded an encoded sequence decoding means; means for generating a high-frequency band; a first-Nth means for calculating a low-frequency band time envelope; time envelope calculation means; time envelope correction means; and a signal output means, wherein the time envelope calculating means calculating the high-frequency band temporal envelope by performing processing using a plurality of low frequency band temporal envelopes, selected based on time envelope information from a plurality of determined processing prepared in advance, and a plurality of determined processing includes a time-domain smoothing process.
EFFECT: technical result consists in the leading and lagging echo reduction.
