FIELD: information technology.
SUBSTANCE: method of forming a masking interference for protecting voice information is to form a noise and masking signal, and then mixing them. In this case, the masking signal is formed by summing the normalized power spectra selected randomly by the speech signal modes obtained by applying the Huang-Hilbert transform to the voice signal recordings of different duration and content.
EFFECT: reducing the power level of the masking noise while maintaining the level of efficiency of protection of voice information from unauthorized listening.
