由于单词边界没有明显的声学标记，如沉默停顿，在句子中查找单词变得困难。最近的实验证据表明，成年人和婴儿都能够在线使用韵律边界线索来限制词汇通达。法国成年人在完成单词识别任务时，会受到语音短语中局部词汇歧义的影响，但不会跨越语音短语边界(Christophe，Peperkamp，Pallier，Block，&Mehler，J.Mem)。语言(修订中))。13个月大的美国婴儿被训练在听到一个双音节单词时转过头，这是一种条件转头范式的变体，他们对包含目标单词的句子的反应比对包含两个音节的句子更频繁(Gout，Christophe，&Morgan，J.Mem)。语言(修订中))。综上所述，这些结果表明，法国成年人和13个月大的美国婴儿都认为语音短语边界是自然的单词边界，他们不会尝试对跨越这种边界的音节对进行词汇通达。我们讨论了这些结果对其他语言的潜在推广性，韵律边界线索的普遍性以及它们在在线句法分析和句法获取中的应用。(C)2003爱思唯尔有限公司。保留所有权利。
Finding words in sentences is made difficult by the absence of obvious acoustic markers at word boundaries, such as silent pauses. Recent experimental evidence suggests that both adults and infants are able to use prosodic boundary cues on-line to constrain lexical access. French adults performing a word detection task were slowed down by local lexical ambiguities within phonological phrases but not across a phonological phrase boundary (Christophe, Peperkamp, Pallier, Block, & Mehler, J. Mem. Language (in revision)). Thirteen-month-old American infants who were trained to turn their heads upon hearing a bisyllabic word, such as 'paper', in a variant of the conditioned head-turning paradigm, responded more often to sentences that contained the target word than to sentences containing both its syllables separated by a phonological phrase boundary (Gout, Christophe, & Morgan, J. Mem. Language (in revision)). Taken together, these results suggest that both French adults and 13-month-old American infants perceive phonological phrase boundaries as natural word boundaries, and that they do not attempt lexical access on pairs of syllables which span such a boundary. We discuss the potential generalization of these results to other languages, the universality of prosodic boundary cues as well as their use in on-line syntactic analysis and syntax acquisition.
