Bilingual advantage in early EFL pronunciation accuracy of German 4th-graders

Aims and Objectives: We compared speech accuracy and pronunciation patterns between early learners of English as a foreign language (EFL) with different language backgrounds. We asked (1) whether linguistic background predicts pronunciation outcomes, and (2) if error sources and substitution patterns differ between monolinguals and heterogeneous bilinguals.Methodology: Monolingual and bilingual 4th-graders ( N = 183) at German public primary schools participated in an English picture-naming task. We further collected linguistic, cognitive and social background measures to control for individual differences.Data and Analysis: Productions were transcribed and rated for accuracy and error types by three independent raters. We compared monolingual and bilingual pronunciation accuracy in a linear mixed-effects regression analysis controlling for background factors at the individual and institutional level. We further categorized all error types and compared their relative frequency as well as substitution patterns between different language groups.Findings: After background factors were controlled for, bilinguals (irrespective of specific L1) significantly outperformed their monolingual peers on overall pronunciation accuracy. Irrespective of language background, the most frequent error sources overlapped, affecting English sounds which are considered marked, are absent from the German phoneme inventory, or differ phonetically from a German equivalent.Originality: This study extends previous work on bilingual advantages in other domains of EFL to less researched phonological skills. It focuses on overall productive skills in young FL learners with limited proficiency and provides an overview over the most common error sources and substitution patterns in connection to language background.Significance/Implications: The study highlights that bilingual learners may deploy additional resources in the acquisition of target language phonology that should be addressed in the foreign language classroom.
