ABSTRACT:
An audio-intonation calibration method in which an audio signal emitted by a subject is reproduced to the auditory organs of the subject after real time processing, which comprises the following steps:acquisition of a model audio signal to be imitated;spectral analysis of the model audio signal;acquisition of an imitation audio signal emitted by the subject;spectral analysis of the imitation audio signal;comparison of the spectra of the model audio signal and the imitation audio signal;correction of the imitation audio signal as a function of the result of said comparison; andreproduction to the auditory organs of the subject of the corrected audio signal.
