Differences in the basic pitch relevant to the perceptual distinction of melodemes in English
Veroňková, Jitka ; Palková, Zdenka (advisor) ; Krčmová, Marie (referee) ; Janota, Přemysl (referee)
As in the case of many other languages, the intonation fulfils certain linguistic functions in Czech. It distinguishes conclusive vs. non-conclusive clauses, declarative vs. interrogative clauses and neutral vs. marked usage clauses. In the case of declarative and interrogative clauses, the intonation is the single distinguishing feature. Structures of the basic patterns to express these linguistic functions were standardized and in general accepted, but not enough is known about their particular realizations. In general, these structure types are realized in the final stress unit of the utterance. It has been confirmed that the intonation courses of some functionally diverse contours are similar and there exist overlaps among them. The perceptual differences between contours can be caused only by the size of F0 excursions. Our research focuses on finding minimal distinctions in F0 excursions which are sufficient to distinguish phonologically different types of sentences. Some structure types can be fully realized on the at least three-syllable stress units, that is why these were chosen to be analysed. The research is based both on synthetic speech and natural one. Two sets of synthetic contours, first containg three-syllable stress units and the second the four-syllable ones, that cover the structure...

Coarticulatory effects of nasal consonants on their segmental context in Czech and English
Skarnitzl, Radek ; Palková, Zdenka (advisor) ; Janota, Přemysl (referee) ; Krčmová, Marie (referee)
This dissertation deals with coarticulatory nasalization in Czech and English. The theoretical part introduces the topic of coarticulation, presents methods used in the research of studies, as well as studies which have analyzed this topic before. In the practical part, the dissertation presents four experiments, which have been largely conducted by means of nasometric analysis. Three experiments analyze vowel nasalance based on segmental and suprasegmental parameters, both in logatoms and connected speech. I was interested in mean nasalance in the respective vowels, as well as in the course of nasalance throughout vowels and vowel-nasal-vowel tokens. In one experiment, I also examine the perceptual aspect of nasality; manipulations of spectral envelope were used to generate the target speechsounds.
