有理由相信，针对婴儿的语音（ID）可能会使婴儿更容易学习语言。然而，ID 言语对婴儿学习的影响仍然知之甚少。这里报告的实验评估了 ID 语音是否有助于从流利的语音中进行分词。一组婴儿听到一组无意义的句子，其语调轮廓具有成人主导 (AD) 语音的特征，而另一组则听到相同的句子，其语调轮廓具有 ID 语音的特征。在这两种情况下，单词边界的唯一提示是语音的统计结构。婴儿在接触 ID 语音后能够区分单词和跨越单词边界的音节序列，但在听到 AD 语音后却不能。这些结果表明，ID 语音有助于分词，并且对于语言习得的其他方面也可能有用。还考虑了优先收听范式中的优先方向问题。
There are reasons to believe that infant-directed (ID) speech may make language acquisition easier for infants. However, the effects of ID speech on infants' learning remain poorly understood. The experiments reported here assess whether ID speech facilitates word segmentation from fluent speech. One group of infants heard a set of nonsense sentences spoken with intonation contours characteristic of adult-directed (AD) speech, and the other group heard the same sentences spoken with intonation contours characteristic of ID speech. In both cases, the only cue to word boundaries was the statistical structure of the speech. Infants were able to distinguish words from syllable sequences spanning word boundaries after exposure to ID speech but not after hearing AD speech. These results suggest that ID speech facilitates word segmentation and may be useful for other aspects of language acquisition as well. Issues of direction of preference in preferential listening paradigms are also considered.
