| Popis: | application/pdf Previous research has shown that L2 learners immersed in a target language environment exhibit phonetic drift in L1 category boundaries along VOT （Chang, 2002, 2010; Tice & Woodley, 2012） and vowel formant （Guion, 2003） dimensions, which subsides after an extended duration of immersion. This study investigates the articulation of sibilant fricatives in Japanese and in English by three groups of bilinguals – a） late bilinguals who have studied abroad; b） late bilinguals with no experience abroad; c） early （simultaneous） bilinguals – to determine whether they differ from one another in distinguishing post-alveolar sibilants of English, [ʃ], and Japanese, [㷡], and whether there is evidence among late bilinguals of phonetic drift in the alveolar sibilant [s] common to both languages under pressure from the novel English post-alveolar. Participants produced real words containing each of the test segments before a high or a low vowel in four blocks, two in English and two in Japanese both in isolation and embedded within a carrier phrase. Productions were recorded and submitted to acoustic analysis. Measurements of spectral Center of Gravity (Hanulíková and Weber, 2010) revealed differences between the two languages only among late bilinguals with no study abroad experience. Without intensive immersion experience, these participants were expected to exhibit no evidence of phonetic drift; however, the pool from which they were recruited was comprised of Japanese university students majoring in linguistics with coursework in English phonetics. We therefore speculate that phonetic drift may not arise solely from intensive exposure in an immersion environment but from heightened perceptual awareness brought about through acquired metalinguistic knowledge as well. It is surmised that any experience of phonetic drift that the other two groups may have had must already have subsided by the time of testing given the extent of their exposure experience. |
