Research has shown that infants perceive many aspects of isolated speech sounds in an adult-like fashion. Little is known, however, about whether infants also organize their perception of continuous speech by segmenting speech into temporally ordered "units" or segments (e.g., phonetic segments or syllables) resembling those of adults. If infants temporally segment speech at some linguistic level, these segments would be denumerable units. An infant's representation of a particular utterance would therefore contain a particular number of these units. If it could be shown that infants can discriminate among utterances or can match them on the basis of the number of units they contain, then segmental competence could be more justifiably attributed to infants. The experimental method we have developed incorporates a numerical ability known to be present during infancy. We are using this ability as a methodological tool to reveal segmental ability. This method has made it possible for us to collect pilot data which strongly suggest that infants can detect the number of syllables in an utterance. The objective of our proposal is to conduct a more extensive and systematic investigation of infants' segmentation of synthetic and natural speech at the level of syllables and the level of phonetic segments. This investigation will have a twofold significance: (a) It will further delineate the language processing capabilities of infants, and (b) it also will further specify the numerical processing capabilities of infants.

研究表明，婴儿感知孤立语音的许多方面 听起来像个成年人然而，人们对是否 婴儿还通过分段来组织他们对连续语音的感知 将语音分成时间上有序的“单元”或段（例如，语音段 或音节）类似于成人的音节。 如果婴儿在时间上 在某种语言水平上，这些片段将是可数的单位。 因此，婴儿对特定话语的表征 包含特定数量的这些单元。如果能证明 婴儿可以区分不同的话语，或者可以根据 它们所包含的单位数量，那么部门能力可能会更多 可归因于婴儿。 我们开发的实验方法结合了数值计算能力 已知在婴儿期出现。我们利用这种能力 方法学工具来揭示分段能力。这种方法使它 我们有可能收集试点数据，这些数据强烈表明， 可以检测出一段话中音节的数量。 我们建议的目的，是进行一项更广泛和更有系统的 婴儿对合成语音和自然语音切分研究 音节层次和语音段层次。这 调查将具有双重意义：（a）它将进一步 描述婴儿的语言处理能力，以及（B）它还 将进一步说明婴儿的数字处理能力。
