ACOUSTIC SIGNAL SEPARATION DEVICE AND METHOD FOR SEPARATING ACOUSTIC SIGNAL

摘要

A determination unit (6) in an acoustic signal separation device (1) determines whether the components from a plurality of sound sources are mixed in the acoustic signal for each component regenerated by a signal regeneration unit (5). When the determination unit determines that a plurality of components is mixed, a series of processes performed by a feature extraction unit (2), a data estimation unit (3), a data classification unit (4), and the signal regeneration unit (5) is repeated until the acoustic signal of a component for each sound source is regenerated.
