Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/205494
Kind Code:
A1
Abstract:
The present invention involves: receiving frequency-divided timesequential acoustic signals and auxiliary information representing target sound information; estimating a convolutional beamformer on the basis of the optimization criterion that, when a convolutional beamformer performing dereverberation, diffusive noise suppression, and target sound source separation, is applied to an acoustic signal, the obtained signal is defined according to a probabilistic model; applying the estimated convolutional beamformer to the acoustic signals, to obtain a processed signal; and outputting the processed signal.
