演講題目： L1 and L2 influences on perception and production of stop voicing distinctions in both languages by sequential, L2-dominant bilinguals
時間：2014 年 7 月 9 日 (星期三) 中午 12 時 30 分
地點：清大人社院 B305 室
摘要：Prior literature on speech perception and production in early sequential bilinguals has provided some interesting but somewhat conflicting results. Some evidence indicates that an L1 influence persists into adulthood in perception or production or both, even in bilinguals who are fluent in everyday use of both languages. But other research suggests there is instead mutual influence on perception and/or production from both thte L1 and the L2, yielding intermediate performance between that of monolinguals of the two languages. Little of the prior research, however, considered the nature of the bilinguals' language environment, nor did it systematically control the language mode (L1 or L2) the participants were placed in during the experimental tasks. I will summarise the results of a series of experiments on L1 and L2 stop voicing production and perception by fluent Greek-English bilinguals in Australia, as compared to monolingual Australian English and Athenian Greek control groups.
The bilinguals were all L2-English dominant, having grown up in English-dominant Sydney Australia, and their language mode (Greek or English, or code-switching) was controlled in all experiments. The results reveal traces of L1-dominance in production of stop voicing (VOT), language mode affects in perceptual categorisation of stop voicing, but L2-dominant influence on stop voicing discrimination in both languages. Results will be discussed with respect to their implications for theories of L2 speech perception and learning, and for various models of bilinguals’ representation of phonetic and phonological properties of their two languages.
