| Summary: | This study investigates the relationship between several quantitative measures of L2 speech complexity, accuracy, and fluency (CAF) by comparing the oral productions of English L2 learners at different proficiency levels. Forty English as a Foreign Language (EFL) learners of varied proficiency levels performed a simple oral task. The performance of the L2 learners was analyzed regarding linguistic complexity, accuracy, and fluency to investigate the interplay of the CAF dimensions and how language proficiency levels (A2, B1, and B2) relate to these dimensions in the speech of EFL learners. This study confirms the prevailing view that the three CAF dimensions are interconnected and that the CAF triad is a useful and valid way to investigate and describe L2 performance development. The results indicate that all three dimensions of CAF significantly predict L2 learnersʼ oral proficiency, that is, from the developmental perspective, L2 learnersʼ output is produced with higher complexity, accuracy, and fluency as they progress to a higher proficiency level. Moreover, the current paper discusses ways to measure CAF. Specific measures of complexity (index of developmental levels), accuracy (syntactic error rate), and fluency (articulation rate, and dysfluency rate) were identified as effective discriminators between proficiency levels.
