FIELD: digital speech encoding.
SUBSTANCE: speech compression system provides encoding of speech signal into bits flow for later decoding for generation of synthesized speech, which contains full speed codec, half speed codec, one quarter speed codec and one eighth speed codec, which are selectively activated on basis of speed selection. Also, codecs of full and half speed are selectively activated on basis of type classification. Each codec is activated selectively for encoding and decoding speech signal for various speeds of transfer in bits, to accent different aspects of speech signal to increase total quality of synthesized speech signal.
EFFECT: optimized width of band, required for bits flow, by balancing between preferred average speed of transfer in bits and perception quality of restored speech.
