METHOD FOR CALIBRATING AUDIO INTONATION Russian patent published in 2008 - IPC G09B19/06 

FIELD: method for calibrating audio intonation; invention may be used, in particular, for oral practice in a language or singing.

SUBSTANCE: in the method for calibrating audio intonation, audio-signal, emitted by subject (S), returns after processing in real time mode to auditory organs of aforementioned subject (S). Claimed method contains following steps: production (E10) of model of audio signal, subject to imitation; spectral analysis (E11) of aforementioned model of audio signal; production (E13) of audio signal, imitated by subject (S); spectral analysis (E15) of imitated audio signal; comparison (E16) of audio signal model spectrums and spectrums of imitated audio signal; correction (E18) of imitated audio signal in accordance with the result of aforementioned comparison; and return (E22) of corrected audio signal to auditory organs of subject (S).

EFFECT: increased quality of audio intonation calibration.
