Abstract
A novel blind source separation of a mixture of two or more voice signals has been proposed in the present paper. The proposed BSS has been focused based on the spatio-temporal gradient analysis which utilizes the linearity among, 1:sound pressure of source signals, 2:particle velocity vector and 3:instanteneous strain tensor of the medium of the observation point.
