Linguistic skills and speaking fluency in a second language

Abstract

This study investigated how individual differences in linguistic knowledge and processing skills relate to individual differences in speaking fluency. Speakers of Dutch as a second language (N = 179) performed eight speaking tasks, from which several measures of fluency were derived such as measures for pausing, repairing, and speed (mean syllable duration). In addition, participants performed separate tasks, designed to gauge individuals' second language linguistic knowledge and linguistic processing speed. The results showed that the linguistic skills were most strongly related to average syllable duration, of which 50% of individual variance was explained; in contrast, average pausing duration was only weakly related to linguistic knowledge and processing skills.
