FIELD: speech recording/reproducing devices.
SUBSTANCE: during encoding speech signals are separated on frames and separated signals are encoded on frame basis for output of encoding parameters like parameters of linear spectral couple, tone height, vocalized/non-vocalized signals or spectral amplitude. During calculation of altered parameters of encoding, encoding parameters are interpolated for calculation of altered encoding parameters, connected to temporal periods based on frames. During decoding harmonic waves and noise are synthesized on basis of altered encoding parameters and synthesized speech signals are selected.
EFFECT: broader functional capabilities, higher efficiency.
