    摘要: According to one embodiment, various characteristic parameters for determining whether an input audio signal is a voice signal or a music signal are calculated and the calculated characteristic parameters are compared with a threshold value for voice determination and a threshold value for music determination. A voice characteristic score is provided to a characteristic parameter indicating voice and a music characteristic score is provided to a characteristic parameter indicating music. Then, based on a difference between a sum total of voice characteristic scores and a sum total of music characteristic scores, it is determined whether the input audio signal is a voice signal or a music signal.

    摘要: A sound quality correcting apparatus includes: an input module; a feature quantity calculator; a score calculator; a modulation spectrum power calculator; a score corrector; and a signal corrector. The input module receives an input audio signal. The feature quantity calculator calculates feature quantities of the input audio signal for each of a plurality of first intervals having a certain time length. The score calculator calculates a score value for each the first interval based on the feature quantities. The modulation spectrum power calculator calculates a power value, at a certain modulation frequency, of a modulation spectrum of the input audio signal. The score corrector corrects score values in the plurality of first intervals that belong to a second interval if a power value calculated in the second interval is larger than or equal to a certain value. The signal corrector corrects the audio signal based on the score values.
