这项研究考察了当语音环境和说话者发生变化时，六个月大的婴儿识别共享语音片段的音节的感知相似性的能力。当从唇鼻音背景类别到齿槽鼻音比较类别发生变化时，“语音”组中的婴儿在头部转动方面得到视觉强化。婴儿最初接受由男性说话者产生的[ma]-[na]对比训练。元音环境和说话者不同的新标记是在复杂性不断增加的几个阶段引入的。在最复杂的阶段，当从 [ma,mi,mu] 到 [na,ni,nu] 的变化发生时，婴儿被要求转头，每个类别的标记都是由男性和女性说话者产生的。 “非语音”对照组使用与语音条件相同的刺激池进行测试。唯一的区别是背景和比较类别中的刺激的选择方式使得声音不能按声学或语音特征进行组织。语音组的婴儿将训练转移到不同说话者和不同元音环境中产生的新标记上。然而，非语音对照组的婴儿很难学习随着实验的进行而引入的语音无关的标记。这些发现表明，婴儿能够识别鼻辅音共享发音位置的相似性，而与说话者和元音环境的变化无关。
This study examined the ability of six-month-old infants to recognize the perceptual similarity of syllables sharing a phonetic segment when variations were introduced in phonetic environment and talker. Infants in a "phonetic" group were visually reinforced for head turns when a change occurred from a background category of labial nasals to a comparison category of alveolar nasals . The infants were initially trained on a [ma]-[na] contrast produced by a male talker. Novel tokens differing in vowel environment and talker were introduced over several stages of increasing complexity. In the most complex stage infants were required to make a head turn when a change occurred from [ma,mi,mu] to [na,ni,nu], with the tokens in each category produced by both male and female talkers. A " nonphonetic " control group was tested using the same pool of stimuli as the phonetic condition. The only difference was that the stimuli in the background and comparison categories were chosen in such a way that the sounds could not be organized by acoustic or phonetic characteristics. Infants in the phonetic group transferred training to novel tokens produced by different talkers and in different vowel contexts. However, infants in the nonphonetic control group had difficulty learning the phonetically unrelated tokens that were introduced as the experiment progressed. These findings suggest that infants recognize the similarity of nasal consonants sharing place of articulation independent of variation in talker and vowel context.
