Patent ID: 7856354

Claim:
A voice/music determining apparatus comprising: a characteristic parameter calculator configured to calculate a plurality of characteristic parameters for determining whether an input audio signal is a voice signal or a music signal; a voice/music characteristic score calculator configured to compare each of the plurality of characteristic parameters calculated by the characteristic parameter calculator with a threshold value for voice determination and a threshold value for music determination, and provide a voice characteristic score to each of the plurality of characteristic parameters having been determined to be voice and provide a music characteristic score to each of the plurality of characteristic parameters having been determined to be music; and a voice/music determining module configured to calculate a difference between a sum total of the voice characteristic scores calculated by the voice/music characteristic score calculating module and a sum total of the music characteristic scores calculated by the voice/music characteristic score calculating module, to determine that the input audio signal is a voice signal when the sum total of the voice characteristic scores is greater than the sum total of the music characteristic scores in a state in which the calculated difference is not less than a preset value, and to determine that the input audio signal is a music signal when the sum total of the music characteristic scores is greater than the sum total of the voice characteristic scores in the state in which the calculated difference is not less than a preset value.
