Abstract
A voice/music determining apparatus is configured to calculate first feature parameters for discriminating between a voice signal and a musical signal; and calculate second feature parameters for discriminating between a musical signal and a background-sound-superimposed voice signal. A first score is calculated to indicate likelihood that the input audio signal is a voice signal or a musical signal as a sum of weight-multiplied first feature parameters. A second score is calculated to indicate likelihood that the input audio signal is a musical signal or a background-sound-superimposed voice signal as a sum of weight-multiplied second feature parameters. It is determined whether the input audio signal is a voice signal or a musical signal on the basis of the first score. Further, it is determined whether the musical signal is the input audio signal is a background-sound-superimposed voice signal on the basis of the second score.
