Abstract

A voice signal processing method includes: converting a first and a second voice signals to a first and a second frequency signals; setting a coefficient of existence representing degree of existence of a target sound and a coefficient of non-existence representing degree of existence of a non-target sound based on a phase difference for each of the predetermined frequencies between the first and the second frequency signals and a target sound existence region indicating an existence position of the target sound; and judging whether the first voice and/or the second voice include the target sound, based on the coefficient of existence, the coefficient of non-existence and a representative value corresponding to either one of the first and the second frequency signals.
