FIELD: information technologies.
SUBSTANCE: speech coding device comprises a coding section of the first level, which performs processing by coding in respect to the input speech signal; a decoding section of the first level, which performs processing by decoding using coded data of the first level; a section for calculation of erroneous transformation coefficients of the first level, which converts the erroneous signal of the first level into a frequency area for calculation of erroneous coefficients of transformation of the first level; and a coding section of the second level, which performs processing by coding in respect to erroneous transformation coefficients of the first level, besides, the coding section of the second level comprises: a setting section; a selection section; a connected strip configuration section, which connects a strip selected from the low-frequency strip, and a fixed strip from the high-frequency strip, in order to configure the connected strip; and a section of coded data generation, which codes erroneous transformation coefficients of the first level, included into the connected strip, in order to generate coded data of the second level.
EFFECT: improved sound quality.
