Bilingual Speech Sound Development During the Preschool Years: The Role of Language Proficiency and Cross-Linguistic Relatedness

Conclusions This study is the first to document developmental changes in the speech patterns of Spanish –English bilingual preschool children over 1 year. Accuracy rates improved significantly in both languages, suggesting that enhanced exposure to the majority language at school may not impede phonological development in the home language. Bootstrapping effects were particularly pronounced on cross -linguistically shared sounds, which suggests that the same underlying skills are utilized in both languages, whereas language-specific singleton consonants and consonant clusters did not appear to benefit from exposure to the other language. The results also suggest an intricate link between phonol ogical skills and morphosyntactic performance at the early stages of development, but a more complex pattern thereafter with differences that may be based on language-specific phonological properties.
