Word stress is crucial for language perception and production as it enables lexical access and speech segmentation. Phonetically, word stress is cued through higher pitch, duration, and intensity. These cues are weighted differently in production and perception by language learners from different backgrounds. Slavic English learners, especially with a fixed-stress West Slavic language background like Czech but also with a variable-stress South Slavic background like Bulgarian face difficulties in word stress acquisition. Their stress placement errors cannot be fully explained by direct transfer and highlight a more complex relation between the target and the native language. This thesis thus aims to explore the perception and production of English word stress cues by speakers of Slavonic Englishes based on evidence from an EEG study on Slavic and German English word stress cue perception and a phonological and phonetic study on Czech English (CzE) features. These findings are used for the conceptualization of a perception and production training tool. First, the concepts of cue and feature are reviewed in an effort to bridge psycho- and sociolinguistics and create credible language stimuli. Then, the Event-Related Potentials study demonstrates that Slavic and German English speakers successfully process first- and second-syllable stress changes cued through pitch, duration, and intensity. Still, speakers of Slavic languages (with a rather syllable-timed rhythm) perceived first and second syllable stress similarly whereas speakers of German (with a rather stress-timed rhythm) perceived the second syllable deviation as more salient. A study on the role of word stress in the CzE feature inventory shows that syllable-timed rhythm also affects production, as speakers lack vowel reduction and add additional stress to longer words. Compared to Bulgarian English (BgE), CzE shows differences in stress features but an overall lack of consistency in their use to differentiate primary from secondary and unstressed syllables. These findings are integrated in the conceptualization of a High-Variability Phonetic Training (HVPT) system featuring segmentals and suprasegmentals. Overall, this thesis finds group differences in foreign language perception and production of word stress and applies them in the development of customized language learning solutions.:List of Figures ix
