目的：本研究调查了说西班牙语和英语的双语儿童的语音节奏习得，比较了他们与功能单语的两种语言的同龄人以及单语和双语成人的语音节奏习得。天])、年龄较大的儿童(4；6.18至5岁；2)和成年人(18岁以上)。在E.Grabe和E.L.Low(2002)的基础上，采用归一化的声部和声间配对变异性指数(PVLS)对26个句子进行了分析。结果：年龄较小的双语儿童在目标语言中表现出明显的语音节奏模式，并且他们偏离了说英语的同龄人。年龄较大的双语儿童也会按语言区分语音节奏，并且年龄较大的双语儿童与说英语的单语同龄人之间也存在差异。年龄较小和年龄较大的双语儿童在发声PVI上存在差异，但在发声间PVI上没有差异，这为年龄差异提供了部分支持。双语成人表现出语言分离，表现出与单语同龄人相似的表现。结论：双语儿童表现出明显的目标语言语音节奏模式，但在发声测量的基础上，早期存在一定的等时偏差，减少了超时。总体而言，声道PVI比声间PVI更健壮，但还需要进一步研究。
Purpose: In this study, the authors investigated speech rhythm acquisition by bilingual Spanish-English-speaking children, comparing their performance with functionally monolingual peers in both languages and to monolingual and bilingual adults.Method: Participants included younger children (3;9 [years;months] to, 4;5.1 5[years;months. days]), older children (4;6.18 to 5;2), and adults (over 18 years). Twenty-six sentences were elicited and analyzed using the normalized vocalic and intervocalic Pairwise Variability Indices (PVls) that express the level of variability in successive duration measurements, on the basis of E. Grabe and E. L. Low (2002).Results: Younger bilingual children displayed distinct speech rhythm patterns for their target languages, and they deviated from their monolingual English-speaking peers. Older bilingual children also separated speech rhythm by language, and differences between older bilingual children and their monolingual peers speaking English were also found. Younger and older bilingual children differed on the vocalic PVI, but not the intervocalic PVI, providing partial support for age differences. Bilingual adults showed separation of their languages and performed similarly to their monolingual peers.Conclusion: Bilingual children show distinct speech rhythm patterns for their target languages but with some early equal timing bias that diminishes overtime, on the basis of the vocalic measurements. Overall, the vocalic PVI is more robust than the intervocalic PVI, but further research is necessary.
