在1个月和4个月大的婴儿中研究了合成语音的辨别。语音变化沿着声学维度先前表明，提示在成人的浊和清塞音之间的音位区别。辨别力是通过在习惯于第一语音后对第二语音的条件反应率的增加来测量的。从习惯化的恢复是更大的一个给定的声学差异时，两个刺激是从不同的成人音素类别比当他们是从同一类别。在成人音位边界区域的歧视的不连续性被视为分类知觉的证据。
Discrimination of synthetic speech sounds was studied in 1- and 4-month-old infants. The speech sounds varied along an acoustic dimension previously shown to cue phonemic distinctions among the voiced and voiceless stop consonants in adults. Discriminability was measured by an increase in conditioned response rate to a second speech sound after habituation to the first speech sound. Recovery from habituation was greater for a given acoustic difference when the two stimuli were from different adult phonemic categories than when they were from the same category. The discontinuity in discrimination at the region of the adult phonemic boundary was taken as evidence for categorical perception.
