Document Type and Number:
Japanese Patent JP3364487
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for separating compound voice data where voice data of several speakers mixedly exist into the voice of every speaker and to provide a method and a device for accurately and quickly specifying the speaker of each separated voice data. SOLUTION: The method for separating compound voice data where voice data of several speakers mixedly exist into the voice data of every speaker has a step (1) where correlation elimination processing is performed to eliminate correlation between the compound voice data and a step (2) where independent component separation processing is performed to separate data subjected to the correlation elimination processing into independent components.
