以普通话为母语的人很难产生像英语一样的重音对比。在声学上，英语的词汇重音是多维的，包括对基频（F0）、持续时间、强度和元音质量的操纵。这些相关因素中的任何一个或所有的错误都可能干扰对重音对比的感知，但对于普通话使用者来说，哪些相关因素最成问题尚不清楚。本研究比较了10名普通话和10名英语母语人士在词汇重音对比中使用这些相关因素的情况。结果显示，说普通话的人产生的与母语相似的重音模式明显更少，尽管他们确实使用了所有四种声学关联来区分重读音节和非重读音节。普通话和英语使用者对重音和非重音音节的振幅和持续时间的使用具有可比性，但普通话使用者产生重音音节的F0高于英语使用者。不同群体的构音模式也存在显著差异，比如说普通话的人在某些非重读音节上会产生类似英语的元音略读，而在其他音节上则不会。结果表明，普通话使用者在英语中产生的词汇重音对比部分受母语经验的影响，部分受普通话和英语元音清单相似性和差异性的影响。
Native speakers of Mandarin Chinese have difficulty producing native-like English stress contrasts. Acoustically, English lexical stress is multidimensional, involving manipulation of fundamental frequency (F0), duration, intensity and vowel quality. Errors in any or all of these correlates could interfere with perception of the stress contrast, but it is unknown which correlates are most problematic for Mandarin speakers. This study compares the use of these correlates in the production of lexical stress contrasts by 10 Mandarin and 10 native English speakers. Results showed that Mandarin speakers produced significantly less native-like stress patterns, although they did use all four acoustic correlates to distinguish stressed from unstressed syllables. Mandarin and English speakers' use of amplitude and duration were comparable for both stressed and unstressed syllables, but Mandarin speakers produced stressed syllables with a higher F0 than English speakers. There were also significant differences in formant patterns across groups, such that Mandarin speakers produced English-like vowel reduction in certain unstressed syllables, but not in others. Results suggest that Mandarin speakers' production of lexical stress contrasts in English is influenced partly by native-language experience with Mandarin lexical tones, and partly by similarities and differences between Mandarin and English vowel inventories.
