Aspiration of English plosives in Czech students of English studies
Pospíšilová, Andrea ; Skarnitzl, Radek (advisor) ; Dušková, Libuše (referee)
Voice onset time (VOT) was shown to provide an effective basis on which to differentiate individual plosives in English. This thesis carries out an analysis of recordings of university students to determine whether specific phonetic in- struction improves pronunciation of non-native speakers of English with focus on aspiration of plosives and VOT. In the first part, a theoretical background is provided with definitions of plosives, VOT and its use and measurement. It also reviews the factors that have been shown to affect the VOT values. In addition, a brief overview of second language acquisition is given, with focus on English pronunciation. The second, empirical part describes the material and method used in the analysis and provides figures and results of statistical tests that were run. The results suggest a significant increase in VOT values as a result of one semester of Phonetics and Phonology course. Furthermore, individual plosives and positions in a word were examined sep- arately to determine whether there are any differences as suggested by the theoretical overview. Keywords: voice onset time, aspiration, Czech English, second language acquisition
