Pre-fortis shortening in Czech English

This bachelor thesis examines the role of a phenomenon called pre-fortis shortening in Czech English. This term is used by phoneticians to represent the shortening of vowels before fortis consonants. It is not characteristic only of English, Matthew Chen even suggested that it could be a language-universal phenomenon. In English it is a very significant feature since English vowel duration was proven by various experiments to serve as a cue to the perception of the voicing characteristic of the following consonant. This thesis advances our understanding of pre-fortis shortening in Czech English where vowel duration was hypothesized to correlate with the speaker's proficiency in English. As a result, this work aims to examine the extent to which 20 Czech students divided into two categories depending on their English level (A2, C1) exploit this phenomenon and whether their proficiency has an impact on vowel durations before fortis and lenis consonants. They were recorded while reading 40 English sentences and their vowel durations were compared to those obtained from two native English speakers
