There is a debate in academia regarding how working memory capacity influences the oral production of second language learners. This study selected 30 advanced Chinese learners as subjects and found that the size of their working memory capacity is significantly correlated with the lexical accuracy, syntactic accuracy, lexical density, lexical complexity, speech rate, and mean length of runs in their oral production. However, there is no significant correlation with phonetic accuracy, lexical diversity, syntactic complexity, articulation rate, and silent pause frequency. The findings of this study help deepen the understanding of the relationship between working memory and the oral production of Chinese learners and provide references and suggestions for Chinese oral teaching.
