In modern society the crucial role belongs to electronic telecommunications, due to which information and financial exchanges between organizations of different forms of property and individuals is performed. Therefore, problems of secure exchange of various resources acquire particular relevance. However, password authentication of users, which now prevails in practical applications, is not able to withstand criticism. Static biometric features of users (facial appearance, fingerprints and iris), which had been tried in different access systems, didn't meet the expectations. Therefore, much attention is currently given to research in the field of voice authentication systems. The object of research is the process of digital signal processing in voice authentication systems. The purpose of research is to improve the quality of voice authentication procedures due to the calculation and analysis of the phase characteristics of digital signal registration materials. The proposed procedure allows dividing the analyzed sequence into the noise sequence and the sequence containing a user voice signal, as well as improving the quality of speech recognition and speaker identification tasks.
