FIELD: automatic voice recognition technologies.
SUBSTANCE: acoustic signal, observed at a point of person body, unknown to unauthorized personnel, is inputted to computing device, values of parameters of acoustic signal are determined, values of estimates of statistical characteristics of parameters of acoustic signal are determined and standards are formed on basis of these, grade of difference between acoustic signal and standards is determined, on basis of aforementioned grade decision is taken whether acoustic signal belongs to person, whose values of statistical characteristics were used during forming of standards.
EFFECT: higher resistance to interference, higher efficiency, higher trustworthiness.
