FIELD: information technologies.
SUBSTANCE: invention consists of a vocoder having at least one input and at least one output, coding device containing a filter having at least one input functionally connected to the vocoder input, and at least one output, decoder containing a synthesiser having at least one input functionally connected to at least one coding device output, and at least one output functionally connected to at least one vocoder output; at that, the coding device contains memory and the coding device is made with the possibility of performing commands stored in memory and containing classification of voice segments and coding of voice segments, and the decoding device contains memory, and the decoding device is made with the possibility of performing commands stored in memory and containing the change of time-scale of the residual voice signal to extended or compressed form of the residual voice signal.
EFFECT: improving voice data coding accuracy.
