人类婴儿（6个月）old）展示了区分2个频谱上不同的元音类别的能力，其中生成元音标记以模拟由男性、女性和儿童说话者产生的标记。在实验1中，婴儿最初被训练区分由计算机模拟的男性声音产生的/a/和/i/标记。然后，他们在一个渐进的学习转移任务中逐渐接触到一些新的标记。在实验2中，婴儿最初被训练辨别相同的元音对比，但随后立即用两个元音类别中的所有标记进行测试。在这两个实验中，婴儿都表现出了从男性说话者产生的训练标记到女性和儿童说话者产生的标记的快速学习转移。这两个实验都提供了强有力的证据，表明6个月。老年婴儿识别的声学类别与成年英语使用者所感知的元音类别一致。
Human infants (6 mo. old) demonstrated the ability to distinguish 2 spectrally dissimilar vowel categories in which the vowel tokens were generated to simulate tokens produced by a male, a female and a child talker. In experiment 1, the infants were initially trained to discriminate the /a/ and /i/ tokens produced by the computer-simulated male voice. They were then gradually exposed to a number of novel tokens in a progressive transfer-of-learning task. In experiment 2, the infants were initially trained to discriminate the same vowel contrast, but were then immediately tested with all of the tokens in both vowel categories. In both experiments the infants demonstrated rapid transfer of learning from the training tokens produced by the male talker to the tokens produced by female and child talkers. Both experiments provide strong evidence that the 6 mo. old infant recognizes acoustic categories that conform to the vowel categories perceived by adult speakers of English.
