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...

Voicing in German speakers'pronunciation of Czech
Pospíšilová, Lucie ; Machač, Pavel (advisor) ; Martínek, František (referee)
The thesis is concerned with the German speakers' pronunciation of the Czech language, specifically with the issue of the voicing of obstruents. The phonological voicing is realized differently in Czech and German and the assimilation of voicing follows diverse principles. The pronunciation is often underestimated in education. The objective of the thesis is to find out the most frequent mistakes and to propose some improvements for tuition. I have thoroughly analysed 20 read speeches made by German speakers. I have also compared course books from the point of view of pronunciation engagement. The most problematic issue appeared to be the assimilation of voicing on the boundaries of syllables and words. The main contribution of the thesis should be the summary of German speakers' pronunciation difficulties and the materials which can be used for further tuition.
