使用头转偏好程序（D. G. Kemler Nelson 等人，1995）在 3 个实验中检查了婴儿对单词的语音模式与说话者声音的索引特性的长期记忆。让婴儿熟悉 2 个单词的重复，并在第二天测试他们对 4 篇文章的定向时间，其中 2 篇文章包括熟悉的单词。 7.5 个月大时，婴儿对包含熟悉单词的段落（当这些单词是由最初的说话者说出的）更感兴趣。在 7.5 个月和 10.5 个月大时，婴儿无法识别新奇女性谈话者所讲段落中的单词。相比之下，7.5 个月大的孩子在两种说话者的情况下都表现出单词识别能力，即当呈现原始说话者和小说说话者所产生的段落时。研究结果表明，特定于说话者的信息可以增强婴儿对单词的记忆，并促进说话者之间的单词识别。
Infants' long-term memory for the phonological patterns of words versus the indexical properties of talkers' voices was examined in 3 experiments using the Headturn Preference Procedure (D. G. Kemler Nelson et al., 1995). Infants were familiarized with repetitions of 2 words and tested on the next day for their orientation times to 4 passages-2 of which included the familiarized words. At 7.5 months of age, infants oriented longer to passages containing familiarized words when these were produced by the original talker. At 7.5 and 10.5 months of age, infants did not recognize words in passages produced by a novel female talker. In contrast, 7.5-month-olds demonstrated word recognition in both talker conditions when presented with passages produced by both the original and the novel talker. The findings suggest that talker-specific information can prime infants' memory for words and facilitate word recognition across talkers.
