Acoustic analyses of normal voiced and whispered Mandarin Chinese reveal significant differences in duration and intensity among the four lexical tones, differences that are moreover similar across the two speech genres. In contrast to previous claims, however, these differences among the tones are found to shrink in whisper rather than being exaggerated to(More)
This study investigated the production of five Mandarin and English sibilant fricatives by heritage speakers of Mandarin in comparison to native speakers and late learners. Almost all speakers were found to distinguish the Mandarin retroflex and alveolo-palatal, as well as the Mandarin alveolo-palatal and English palato-alveolar. However, fewer(More)
This study tested the hypothesis that heritage speakers of a minority language, due to their childhood experience with two languages, would outperform late learners in producing contrast: language-internal phonological contrast, as well as cross-linguistic phonetic contrast between similar, yet acoustically distinct, categories of different languages. To(More)
Studies of proficient second-language (L2) learners have often noted phonetic drift of their native language (L1) vis-à-vis monolingual norms. Such drift has been attributed to perceptual linkage between similar sounds in L1 and L2. This study provides evidence that L1 phonetic drift is limited neither to advanced L2 learners, nor to crosslanguage influence(More)
Phonological transfer from the native language is a common problem for non-native speakers that has repeatedly been shown to result in perceptual deficits vis-à-vis native speakers. It was hypothesized, however, that transfer could help, rather than hurt, if it resulted in a beneficial bias. Due to differences in pronunciation norms between Korean and(More)
