Напрямки удосканалення процедур попередньої обробки голосових сигналів у системах автентифікації

Abstract

The actual scientific problem of carrying out preprocessing of a voice signal in authentication systems is considered. In contrast to the well-known works in which pre-processing of signals is carried out using amplitude-frequency information, it is proposed to carry out the specified processing using the phase space. The prerequisite for this is that the phase signal changes linearly within the specified limits. Research has shown that this approach has been successful. A technique for conducting preliminary processing of voice signals in the phase space has been developed.
