Abstract

In this paper we propose a method for speaker change detection using features of excitation source of the speech production mechanism. The method uses neural network models to capture the speaker-specific information from a signal that represents predominantly the excitation source. The focus in this paper is on speaker change detection in casual telephone conversations, in which short (
