本研究通过四个实验来探讨英语学习婴儿是否能利用同音字线索从流利的语音中切分出单词。婴儿熟悉一对双音节项目，如硝酸盐和夜间速率，然后测试他们在流利的言语段落中检测这些相同单词的能力。存在的allophonic线索字边界没有帮助g个月奥尔兹的孩子区分一个熟悉的话从一个声学上类似的箔。熟悉硝酸盐的婴儿听关于夜间心率的段落和听关于硝酸盐的段落的可能性一样大。然而，当段落中包含有利于提取熟悉目标的分布线索时，9个月大的婴儿能够从流利的语言中分割出这些项目。到10.5个月大的时候，婴儿能够仅仅依靠变音线索来定位段落中熟悉的目标词。我们认为这些发现有什么影响，了解如何分词技能的发展。
A series of four experiments was conducted to determine whether English-learning infants can use allophonic cues to word boundaries to segment words from fluent speech. Infants were familiarized with a pair of two-syllable items, such as nitrates and night rates and then were tested on their ability to detect these same words in fluent speech passages. The presence of allophonic cues to word boundaries did not help g-month-olds to distinguish one of the familiarized words from an acoustically similar foil. Infants familiarized with nitrates were just as likely to listen to a passage about night rates as they were to listen to one about nitrates. Nevertheless, when the passages contained distributional cues that favored the extraction of the familiarized targets, 9-month-olds were able to segment these items from fluent speech. By the age of 10.5 months, infants were able to rely solely on allophonic cues to locate the familiarized target words in passages. We consider what implications these findings have for understanding how word segmentation skills develop.
