ABSTRACT:
According to one embodiment, sound quality control processing for speech or music is performed by calculating various kinds of characteristic parameters to determine a speech signal and a music signal from an input audio signal and determining the input audio signal closer to the speech signal or music signal based on a score difference between a sum of scores provided to characteristic parameters indicating the speech signal and that of scores provided to characteristic parameters indicating the music signal.
