超音段参数（基频、振幅和持续时间）对1 ~ 4个月多音节序列识别的影响。确定了10岁的婴儿。采用了高振幅的吸吮程序，并合成了女性语音。当婴儿指向语的超节段特征强调中间音节时，婴儿可以区分3音节序列[marana]和[malana]。当使用成人引导的超音段时，以及在其他几个韵律参数被操纵的实验条件下，婴儿未能表现出辨别能力。婴儿指示语中夸张的超音段可能起到知觉催化剂的作用，通过将婴儿的注意力集中在多音节序列中的一个独特音节上，促进了辨别。
The effects of suprasegemntal parameters (fundamental freuqency, amplitude and duration) on discrimination of polysyllabic sequences by 1- to 4-mo.-old infants were ascertained. A high-amplitude sucking procedure, with synthesized female speech, was used. Young infants can discriminate the 3-syllable sequences [marana] vs. [malana] when suprasegmental characteristcs typical of infant-directed speech emphasize the middle syllable. Infants failed to demonstrate discrimination when adult-directed suprasegmentals were used and in several other experimental conditions in which prosodic parameters were manipulated. The exaggerated suprasegmentals of infant-directed speech may function as a perceptual catalyst, facilitating discrimination by focusing the infant''s attention on a distinctive syllable within polysyllabic sequences.
