Description	Tento článek představuje expertní systém pro verifikaci řečníka. Naším hlavním úkolem bylo navrhnout nástroj pro kombinaci různých verifikačních systémů navrzených pro různé operační podmínky. (cs) The article introduces an expert system for the speaker verification task. Our main purpose was to design a tool for the combination of various speaker verification systems proposed for various operating conditions. First of all, the essential ideas are explained that made us design the expert system. Next section describes the structure of a rule-based expert system and subsequently an oriented graph is proposed for the representation of the topology of the system. The expert rules exploited by the system are derived automatically from the input data and we have implemented also a certainty factor to acquire more reliable decisions. The experiments show that the proposed system has the capability to significantly improve the verification results in trials with various operating conditions.
