This paper presents a model description used for the speakers’ segmentation task. The iterative formulas approximating distribution of a posteriori speakers’ model parameters based on the made assumptions are given and the new original method for initializing model parameters is offered. The scheme of a speakers’ segmentation system based on developed approach is presented. The application of developed system gives relative reduction in error rate up to 26% both at Russian and English speech data bases.
