成人听众对说话者语音片段的协同发音（或共同产生）所产生的声学变化很敏感。本研究通过检查幼儿对摩擦元音音节中的协同发音效应的反应，绘制了幼儿这种敏感性的发展情况。 3、4、5 和 7 岁的儿童和成人从合成的/∫/-/s/连续体中识别标记，后跟四个自然语音部分之一：/i/和/u/，产生适合/∫/或/s/的过渡。与成人相比，儿童的摩擦音音素边界随着语音转换的变化表现出更大的变化，但随着元音质量的变化相对较小。儿童的反应不如成人的一致，并且随着儿童年龄的增长，儿童和成人之间的差异缩小。总体而言，这些结果表明，对某些协同效应的知觉敏感性早在 3 岁时就已存在。此外，随着年龄的增长，对声音转换的敏感性下降，这表明，与普遍持有的观点相反，随着孩子的成长，言语的感知组织可能会变得更加分段，而不是更少。
Adult listeners are sensitive to the acoustic variations that result from a speaker's coarticulation (or coproduction) of phonetic segments. The present study charted the development of such sensitivity in young children by examining their responses to coarticulatory effects in fricative-vowel syllables. Children, at each of the ages 3, 4, 5, and 7 years, and adults identified tokens from a synthetic/∫/-/s/continuum followed by one of four natural vocalic portions:/i/and/u/, produced with transitions appropriate for either/∫/or/s/. Children demonstrated larger shifts in fricative phoneme boundaries as a function of vocalic transition than did adults, but relatively smaller shifts as a function of vowel quality. Responses were less consistent for children than for adults, and differences between children and adults decreased as children increased in age. Overall, these results indicate that perceptual sensitivity to certain coarticulatory effects is present at as young as 3 years of age. Moreover, the decrease in the sensitivity to vocalic transitions with age suggests that, contrary to a commonly held view, the perceptual organization of speech may become more rather than less segmental as the child develops.
