Abstract:
A signal processing device includes a prior distribution storage that stores a prior distribution group that is a set of prior distributions representing representative spectral shapes of spectral bases of an acoustic event specified as a detection target, and a basis generation unit that, using as input a spectrogram for basis generation, generates an acoustic event basis group that is a set of the spectral bases of the acoustic event specified as a detection target. The basis generation unit performs sound source separation on the spectrogram for basis generation and thereby generates an acoustic event basis group, using respective prior distributions included in a prior distribution group as a constraint for spectral bases of a corresponding acoustic event.

Claim (Index 16):
The signal processing device according to  claim 14 , wherein\n the sound source separation unit performs sound source separation on the spectrogram of the acoustic signal for sound source separation by using a spectral basis set that is obtained by appending spectral bases corresponding to a sound other than a sound from the specific sound source to the acoustic event basis group and causing spectral bases in the acoustic event basis group within the spectral basis set to be learned using respective prior distributions included in a prior distribution group as a constraint and causing unknown spectral bases to be learned without constraint.
