Abstract

It is an object to provide a speaker selection apparatus that can suppress deterioration in accuracy of an adaptive model. The speaker selection apparatus is provided with a speaker distribution density calculation means that calculates the density of distribution of a plurality of speakers where an uttering speaker takes a leading part of a speaker space by using a characteristic quantity extracted from an input voice signal of the uttering speaker and speaker models of a plurality of speakers stored in advance, and a selected speaker number calculation means that calculates the number of speakers to be selected by using the speaker distribution densities.
