This study focuses on English onset cluster production in spontaneous speech samples of 10 children aged 5;04-6;09 from Chinese and Hindi/Punjabi first language (L1) backgrounds, each with less than a year of exposure to English. The results suggest commonalities between early second language (L2) learners and both monolingual and adult L2 learners in the location of cluster repair and the sometimes-exceptional treatment of s+stop clusters. We also provide evidence that accuracy rates and repairs used in early L2 cluster production show L1 influences. We conclude that early L2 learners represent a unique learner group, whose study is crucial to the understanding of phonological development.
