Abstract
In this paper, the improvements of the speaker verification system, which is used at Department of Cybernetics at University of West Bohemia, are introduced. The paper summarizes our actual pieces of knowledge in the acoustic modeling domain, in the domain of the model creation and in the domain of score normalization based on the universal background models. The constituent components of the state-of-art verification system were modified or replaced by virtue of the actual pieces of knowledge. A set of experiments was performed to evaluate and compare the performance of the improved verification system and the baseline verification system based on HTK-toolkit. The results prove that the improved verification system outperforms the baseline system in both of the reviewed criterions – the equal error rate and the time consumption.
The work was supported by the Ministry of Education of the Czech Republic, project No. MSM 235200004, and by the Grant Agency of the Czech Republic, project No. 102/05/0278.
