通过考察说话者的可变性对流利语音中单词识别的影响，探讨了婴儿对单词发音模式的表征。婴儿先熟悉一个说话者的孤立单词(例如，杯和狗)，然后听另一个说话者说出的4段话，其中2段包括熟悉的词。在7.5个月大时，婴儿对由2名女性说话者或2名男性说话者产生的材料的熟悉单词的段落的注意时间更长，但对男性和女性说话者的材料没有注意。这些发现表明，说话者的声音相似性在婴儿概括单词符号的能力中起着重要作用。到10.5个月时，婴儿就能在异性说话者之间概括出同一个词的不同情况。本研究结果的一个含义是，婴儿对单词声音结构的初始表征不仅包括语音信息，还包括与特定说话者的声音特征有关的索引属性。
Infants' representations of the sound patterns of words were explored by examining the effects of talker variability on the recognition of words in fluent speech. Infants were familiarized with isolated words (e.g., cup and dog) from 1 talker and then heard 4 passages produced by another talker, 2 of which included the familiarized words. At 7.5 months of age, infants attended longer to passages with the familiar words for materials produced by 2 female talkers or 2 male talkers but not for materials by a male and a female talker. These findings suggest a strong role for talker-voice similarity in infants' ability to generalize word tokens. By 10.5 months, infants could generalize different instances of the same word across talkers of the opposite sex. One implication of the present results is that infants' initial representations of the sound structure of words not only include phonetic information but also indexical properties relating to the vocal characteristics of particular talkers.
