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 13):
The signal processing device according to  claim 11 , wherein\n in each of subsets for each acoustic event included in the acoustic event basis group, two or more spectral bases in which different variations or fluctuations are expressed with respect to a representative spectral shape of a sound constituting the acoustic event are included.
