The paper is a proposal of concept of highlighting the sound sources based on the phase shifts of successive harmonics in a single function course extracted from a articulation of single sound which frequency is stable in short-term. The function describing the single period of sound is expanded for the purpose of determining the harmonic series from − ∞ to + ∞. It is also an additional protection of sensitive personal data, because, based on such generated sound it is impossible to unambiguously recognize the voice of the individual using the human senses.
