DEVICE, METHOD AND CORRESPONDING COMPUTER SOFTWARE FOR THE ERRORS CONCEALMENT SIGNAL GENERATION USING THE INDIVIDUAL LPC REPLACEMENT REPRESENTATIONS FOR THE INDIVIDUAL CODE BOOKS INFORMATION Russian patent published in 2018 - IPC G10L19/05 G10L19/06 

FIELD: analysis or synthesis of speech; speech recognition.

SUBSTANCE: invention relates to the errors concealment signal generation means. Generating the LPC replacement representation. Filtering the codebook information using the replacement LPC representation to produce the replacement signal from which the errors concealment signal is produced. Evaluating the noise during the authentic audio frames reception, at that, the noise evaluation depends on the authentic audio frames and at that the noise evaluation is produced from the past decoded signal. At that, the produced at the noise evaluation performance stage noise evaluation is used in the generation of the LPC replacement representation.

EFFECT: technical result is improved sound quality.
