Apparently homophonous sequences contain acoustic information that differentiates their meanings (Gahl, 2008; Quené, 1992). Adults use this information to segment embedded homophones (e.g., vs. ; Salverda, et al., 2003) in fluent speech. Whether children also do this is unknown, as is whether listeners of any age use such information to disambiguate lexical homophones. In two experiments, 48 English-speaking adults and 48 English-speaking 7- to- 10-year-old children viewed sets of four images and heard sentences containing phonemically identical sequences while their eye movements were continuously tracked. As in previous research, adults showed greater fixation of target meanings when the acoustic properties of an embedded homophone were consistent with the target than when they were consistent with the alternate interpretation. They did not show this difference for lexical homophones. Children's behavior was similar to that of adults, indicating that the use of subphonemic information in homophone processing is consistent over development.
明显同音序列包含区分其含义的声学信息（加尔，2008年；奎内，1992年）。成年人在流利的言语中利用这些信息来切分嵌入的同音词（例如， 与 ；萨尔韦尔达等人，2003年）。儿童是否也这样做尚不清楚，任何年龄段的听众是否利用此类信息来消除词汇同音词的歧义也不清楚。在两项实验中，48名说英语的成年人和48名7至10岁说英语的儿童观看了四组图像，并在他们的眼球运动被持续跟踪时听到包含音素相同序列的句子。与之前的研究一样，当嵌入同音词的声学特性与目标一致时，成年人对目标含义的注视时间比对替代解释一致时更长。对于词汇同音词，他们没有表现出这种差异。儿童的行为与成年人相似，表明在同音词处理中使用亚音位信息在整个发育过程中是一致的。
