Abstract

This study examined the linguistic dimensions of comprehensibility and perceived fluency in the context of L2 argumentative speech elicited from 40 Japanese-speaking learners of English. Their speaking performance was judged by 10 inexperienced native speakers of English for comprehensibility and perceived fluency, and was also objectively analyzed in terms of complexity, accuracy, and fluency as well as pronunciation and discourse features. The results showed that comprehensibility and fluency judgments strongly correlated with each other and that native listeners were significantly more severe when they judged fluency. Furthermore, multiple regression analyses revealed that both constructs were commonly associated with a set of underlying linguistic dimensions (grammatical accuracy, breakdown fluency, and pronunciation). However, comprehensibility was best predicted by articulation rate (speed fluency) whereas perceived fluency was most strongly associated with the frequency of mid-clause pauses (breakdown fluency).
