对婴儿双音节发声中韵律的声学相关性进行了一项调查，该调查基于10名美国和芬兰语学习婴儿和5名法语和威尔士语学习婴儿在开始使用单词时（10-18个月）的数据。对639个双音节的持续时间、强度和基频进行声学分析。婴儿对这三种声音线索的产生模式不同，尽管他们在产生强度和音量方面表现出高度的可变性。接触这四种语言中的每一种的婴儿都表现出最后音节延长的迹象，并产生第一音节和第二音节的重读或重音双音节。然而，芬兰和威尔士的婴儿分别产生了更多的扬格和抑扬格模式。人们认为，在开始使用单词时使用声学韵律线索反映了生物倾向和对韵律线索的反应的结合，韵律线索在输入信号中显示出一致性，而更完整地整合韵律和分词特征似乎需要更多的词汇知识或经验。(C) 2008 Elsevier Ltd版权所有。
An investigation of the acoustic correlates of prosody in infant disyllabic vocalizations was undertaken on the basis of data from 10 each of American- and Finnish- and five each of French- and Welsh-learning infants at the onset of word use (10-18 months). The 639 disyllables were analyzed acoustically for duration, intensity and fundamental frequency (f0). The infants differed in their production patterns with regard to all three acoustic cues, although they agreed in exhibiting high variability in the production of intensity and f0. Infants exposed to each of the four languages showed evidence of final syllable lengthening and the production of both first- and second-syllable-stressed or accented disyllables. However, Finnish and Welsh infants produced proportionally more trochaic and iambic patterns, respectively. The use of acoustic prosodic cues at the onset of word use is argued to reflect a combination of biological predispositions and response to prosodic cues that show consistency in the input signal, while a more complete integration of prosody and segmental features seems to require more lexical knowledge or experience.
