Title:
SOUND SOURCE SEPARATION DEVICE, METHOD THEREOF, AND PROGRAM
Document Type and Number:
Japanese Patent JP2019193073
Kind Code:
A
Abstract:
To provide a sound source separation device with higher separation accuracy than before.SOLUTION: The sound source separation device includes: a diffusive noise removal part configured to remove an estimated diffuse noise signal from observed signal and to obtain the removed signal; a filter design part configured to obtain a filter by combining the probability distribution of modeled removed signal and the probability distribution of modeled transfer function; and a sound source separation part configured to separate noise component estimate value including at least first acoustic signals and coherent noise acoustic signals from observed signal by the filter.SELECTED DRAWING: Figure 4
