Title:
SOUND SOURCE SEPARATION DEVICE, METHOD THEREFOR, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/208137
Kind Code:
A1
Abstract:
Provided is a sound source separation technology device having higher separation precision than conventional devices. The sound source separation device has: a diffuse noise removal unit that removes an estimated value for a diffuse noise acoustic signal from an observation signal and finds a removed signal; a filter design unit that obtains a filter by combining a probability distribution that models the removed signal and a probability distribution that models a transfer function; and a sound source separation unit that separates at least a first acoustic signal and an estimated value for a noise component including an interference noise acoustic signal, from the observation signal by using the filter.
