Electropalatographic study of voicing assimilation in Czech alveolar plosives
Vaněčková, Kateřina ; Skarnitzl, Radek (advisor) ; Machač, Pavel (referee)
The phonological contrast of voicing is based on several phonetic differences which are yet to be satisfactorily explained. The most obvious of them is the presence of vocal cords vibration which has so far been considered crucial in Czech. For capturing the differences in other dimensions, the concept of the strength of articulation, or fortis/lenis contrast have been established. There are some rare cases in languages when the couple of phonemes with the voicing contrast differs also in another feature that cannot be explained by the fortis/lenis dimension correlates. This is the case of Czech alveolar plosives which have been described to differ in their place of articulation: the linguopalatal contact is more anterior for [t] that for [d]. The main aim of this study is to ascertain whether this contrast can indicate the original phoneme in the contexts where the voicing contrast is neutralized due to assimilation. Nevertheless, our electropalatographic data from 7 speakers of Czech show that not only the phonemes do not seem to influence the anteriority of the voicing realisation, but also the very asymmetry of linguopalatal contact in the voicing realisations tends to be neutralised in the segmental context used in our study, that is in coda position in the word-final syllable followed by the...

Static and dynamic characteristics of the linguopalatal contact of the Czech /ř/
Pavlíková, Miriam ; Skarnitzl, Radek (advisor) ; Veroňková, Jitka (referee)
An unique Czech fricative thrill - /ř/ - was studied mainly by Dr. Hála and Dr. Chlumský in the first half of the twentieth century. The methods employed were rather simple and the experiments were done on limited sample size. We decided to revisit and extend the results with electropalatography (EPG). Four female and three men participated in the experiments that were based on reading aloud voiced and voiceless /ř/ in various contexts. We dedicated a short part to dynamic characteristics of /ř/ and focused predominantly on the area of linguopalatal contact. We described the points of linguopalatal contact during /ř/ with adjusted anteriority index (CA). The possible factors affecting the CA are discussed. We scrutinized the differences in CA depending on selected factors for the whole group and each participant. The data suggest that thrill /ř/ occurs in the alveolar area. Anteriority index was chiefly dependent on voicing /ř/, type of the read material and also differed among various speakers.

Linguopalatal contact in Czech palatal stops
Bartošová, Petra ; Skarnitzl, Radek (advisor) ; Machač, Pavel (referee)
The topic of this bachelor thesis is an articulation analysis of Czech palatal stops [ť] and [ď] using electropalatography. The aim of the thesis is to analyse the average and maximum rate of linguopalatal contact in the palatal area as well as to examine the dynamic process of this contact. It also features a short analysis of occlusion duration of Czech palatal stops. The theoretical part of the thesis contains a description of stop consonants, palatals, and the research method - electropalatography. Since thorough analysis of such speech sounds in Czech has not been extensive, the thesis should contribute to a more detailed look on articulation effects during the production of Czech palatal stops. It should also explore the impact of several factors on the production of those speech sounds - in particular voicing, differences between speakers, vocalic environment and nature of the material. In addition, it might be valuable among EPG studies as a considerable number of different speakers (6) is analysed.
