Title:
SOUND SOURCE SEPARATION DEVICE AND SOUND SOURCE SEPARATION METHOD
Document Type and Number:
Japanese Patent JP2012042953
Kind Code:
A
Abstract:

To provide a sound source separation device and a sound source separation method which can separate a sound source signal even when a sound source varies.

The sound source separation device includes: a transfer function storage section for storing a transfer function from a sound source; a sound source variation detection section for generating variation state information indicating variation of the sound source based on an input signal input from a sound collection section; a parameter selection section for calculating an initial separation matrix based on the variation state information generated by the sound source variation detection section; and a sound source separation section for separating the sound source of the input signal input from the sound collection section using the initial separation matrix calculated by the parameter selection section.
