Abstract
A sound processing apparatus includes a feature value extractor configured to perform a Fourier transform and then a cepstral analysis of a sound signal and to extract, as feature values of the sound signal, values including frequency components obtained by the Fourier transform of the sound signal and a value based on a result obtained by the cepstral analysis of the sound signal.
