This work provides a description of an automatic speaker verification (ASV) system. In particular, it documents the evolution of all individual stages of the proposed ASV system design from the phase of preprocessing to an operational decision making system. The aim of this research was to achieve the system of the best safety and ease of use in view of users. The objective estimation of this target has been accomplished by assessing the probability that the presented system will make erroneous decisions. Few different sentences spoken in Polish by several persons have been used as acoustic material. The research resulted in specifying precise parameters for algorithms used in the system and in defining the directions of future research in this field.
