Description
  • Tato práce popisuje výzkum v oblasti fonetické segmetnace v plynulé české řeči. Hlavním cílem je překonání nepřesností segmentace v důsledku chybějícího modelování glotální pausy. Zahrnutý HMM model této hlásky byl trénován iterativní procedurou neboť v dostupných řečových databázích není glotální pausa anotována. Realizované experimenty ukázaly, že modelování glotální puasy bylo úspěšné a že přineslo zvýšení přesnosti fonetické segmentace. Dále byly realizovány pokusy se změnami ve struktuře HMM modelů. Uvedené změny však nepřinesly globální zlepšení, přesnost se zvýšila pouze v některých kontextech. (cs)
  • The research within phonetic segmentation of real fluent Czech speech is presented this work. The main goal of this work was to overcome segmentation in-accuracy due to missing modelling of glottal-stop. HMM model for glottal-stop was trained using iterative procedure because we are working with training data with no manually annotated information about glottal-stop presence in particular utterances. Experiments realized within this work confirmed the improvement of phonetic segmentation with glottal-stop modelling and also performed localization of glottal-stop presence was generally successful. Finally, the experiments with changes in HMM structure were realized, however the results confirm the improvement for several phone contexts only.
