Description
  • Tato práce se zabývá úlohou verifikace řečníka. Konkrétně vylepšeními z poslední doby, které byly integrovány do nového systému verifikace řečníka na Katedře Kybernetiky Západočeské Univerzity. Vylepšení se týkají v podstatě všech hlavních částí verifikačního systému: Zpracování signálu, akustického modelování i normalizace skóre. (cs)
  • 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.
