This article reviews recent research on bilingual phonological development and describes the nature of bilingual phonology, focusing on characteristics of cross-linguistic influence on bilingual phonological abilities. There is evidence of positive and negative transfer (acceleration and deceleration) on children's phonological abilities. Several methodological issues limit the ability to generalize findings from previous research to larger groups of bilingual children (e.g., small sample size, lack of consideration of age of acquisition of each language, and language abilities of the participants). Sources of heterogeneity in language development are presented and discussed. Phonological abilities are related to language abilities in bilingual first language learners of English and Spanish. Empirical evidence from research in our laboratory supports this claim. We discuss implications of research findings and limitations for future research and clinical practice. We provide specific recommendations for bilingual research and for clinical assessment of young bilingual children.
本文回顾了近期关于双语语音发展的研究，并描述了双语语音的本质，重点关注跨语言影响双语语音能力的特征。有证据表明儿童的语音能力存在正向和负向迁移（加速和减速）。几个方法学问题限制了将先前研究结果推广到更大群体双语儿童的能力（例如，样本量小、未考虑每种语言的习得年龄以及参与者的语言能力）。本文呈现并讨论了语言发展中异质性的来源。在英语和西班牙语的双语第一语言学习者中，语音能力与语言能力相关。我们实验室研究的实证证据支持这一观点。我们讨论了研究结果的意义以及对未来研究和临床实践的局限性。我们为双语研究和对双语幼儿的临床评估提供了具体建议。
