This study compared the ability of English monolinguals and Mandarin–English bilinguals to make use of English contrastive prosody not only in natural speech but also in masked speech, in which the only available information was prosodic. In contrast to earlier studies (Choi et al., 2019; Choi, 2021; Tong et al., 2015) which found that L1 tone language speakers outperformed native speakers in tasks involving the use of pitch to identify stress position in English, we did not find a similar advantage for Mandarin–English bilinguals in the interpretation of English contrastive prosody, even under conditions that enforced reliance on pitch contours. These findings are consistent with other studies suggesting that the integration of prosodic information into discourse is an area of particular difficulty for L2 speakers.

In some languages, syllable weight depends exclusively on vowel length, while in others, coda consonants add weight to syllables. In this paper we assume that syllable weight is reflected in moraic structure, and that weight-bearing coda consonants are the exclusive dependents of a mora, while weightless consonants share a mora with the preceding vowel. We consider whether the durations of vowels and coda consonants reflect the distinction between a segment which occupies its own mora and a segment that shares a mora. We examine three patterns of coda weight, reflected in stress assignment: in Hindi, codas always contribute to syllable weight; in Malayalam, coda consonants are always weightless; and in Levantine Arabic, coda weight is contextually determined, with word-internal codas contributing to syllable weight following a short vowel, but weightless following a long vowel. These phonological patterns translate into different moraic representations of CVC and CVVC syllables across the different languages. We examine the durations of vowels and coda consonants in CV, CVC, CVV and CVVC syllables in Hindi, Malayalam and Levantine Arabic, and find that in all three languages, segments that we represent as mora-sharing are significantly shorter than segments that we represent as occupying an independent mora. The striking differences in durational patterns across the three languages correlate with the different moraic representations proposed on the basis of phonological patterning.

This paper discusses the simplification of forms ending in obstruents by native speakers of Mandarin, in particular two effects that are not obviously motivated by either the native- or the target-language grammars: a tendency to devoice final voiced obstruents and a tendency to maximize the number of bisyllabic forms in the output. These patterns are accounted for within Optimality Theory, which describes a grammar as a set of universal, ranked constraints. It is argued that the devoicing and bisyllabicity effects result from universal markedness constraints that are present in all grammars but that are masked in the learner's native-language grammar by the effects of higher ranking constraints.
