FIELD: electrical communications; regions related to reduction of transferred information redundancy.
SUBSTANCE: proposed method includes generation of vector of voice-signal acknowledged readings from one-dimensional voice signal during additional information transfer that incorporates N items and is converted to digital form including additional information being built in. Entered in definite location of each original voice signal block incorporating n bits are m bits of additional information, and trial inversion procedure is used for remaining k = n - m bits. Then blocks incorporating optimized bits and additional information are transferred to digital communication channel. Additional information is separated and original voice message is recovered basing on blocks received from communication channel.
EFFECT: ability of telephone communications over low-speed digital communication channels.
