2 至 4 个月大的婴儿能够辨别共振峰过渡持续时间不同的合成语音模式；这种变化提供的信息足以表明成年听众中塞音和半元音之间的语音区别。此外，过渡持续时间的给定差异的可辨别性是特定刺激值和音节总持续时间的函数。即使音节持续时间的信息出现在转换信息之后，也会发生这种上下文效应。所获得的不连续可辨别性模式符合关系性和分类性的感知。
Infants, aged 2 to 4 months, discriminated synthetic speech patterns that varied in duration of the formant transitions; this variation provides information sufficient to signal the phonetic distinction between a stop consonant and a semivowel in adult listeners. In addition, the discriminability of a given difference in transition duration was a function of both the particular stimulus values and the total duration of the syllable. This contextual effect occurred even though the information for syllable duration came after the transition information. The obtained pattern of discontinuous discriminability was in accord with perception that is relational and categorical.
