Speaker identification systems are based on the fact that speakers differ in their anatomy and in their speech habits. In identical twins the anatomy is identical, or at least very similar, so that speech habits are the main cause for speech differences. Ten pairs of identical twins were recorded and identified using a minimum distance classifier. The distribution of distances from a subject to his twin and to the "world" are analyzed using various features. F-Ratios and text independent identification results are presented and discussed.
