ACOUSTIC SIGNAL SEPARATION DEVICE AND METHOD FOR SEPARATING ACOUSTIC SIGNAL

WIPO Patent Application WO/2019/102585

A1

A feature extraction unit (2) extracts a feature (b) for classification and a feature (c) for signal regeneration from an input signal (a). A data estimation unit (3) estimates data (d) for classification for inter-component mapping of acoustic signals output from the same sound source using DNN (3a) on the basis of the feature (b) for classification. A data classification unit (5) classifies the data (d) for classification for each component on the basis of classification parameter data (e) in which a classification condition is established, the classification parameter including information associated with at least either the number of components in the acoustic signals or the types of components in the acoustic signals. A signal regeneration unit (6) regenerates a signal for each component on the basis of data (f) for classification and the feature (c) for signal regeneration.
