FIELD: physics, communication.
SUBSTANCE: invention relates to system of telecommunication and is intended for coding voice signals based on variable-structure system. Proposed method of encoding comprises separating the input voice signal segments into six classes, i.e. a pause, tone segment, noise segment of the first type, noise segment of the second type, transition segment of the first type, transition segment of the second type, and encoding of the input voice signal recognised segments by various methods, varying the coding system structure.
EFFECT: improved quality of synthesised voice signal at fixed low transmission rate.
