FIELD: information technologies.
SUBSTANCE: method for transfer of voice signals consists in the fact that signals of voice signal envelope and voice signal instantaneous frequency singled out from voice signal are transformed on the basis of pulse-code modulation, digital signal is formed with time interleaving, including signals of voice signal envelope and voice signal instantaneous frequency transformed with pulse-code modulation, and digital signal with time interleaving is sent to digital communication channel, and on receiving side multiplexed digital signal is divided and transformed into analog signal of voice signal envelope and analog signal of instantaneous frequency, which is transformed into cosine signal of instantaneous frequency of voice signal, afterwards synthesis of voice signal is realised by means of voice signal envelope multiplication by cosine signal of voice signal instantaneous frequency.
EFFECT: reduced speed of voice signal coding, narrowing of frequency band occupied with transferred signals, and preservation of high quality of information recovery.
