Diving Deep Into the Relationship Between Speech Fluency and Second Language Proficiency: A Meta‐Analysis

Open access
Yan, Xun, Lei, Yuyun, Pan, Yulin·2025·Language Learning

Abstract

Abundant research has indicated fluency features as meaningful predictors of second language proficiency. However, the extent to which different fluency dimensions and features can predict proficiency remains underexplored. This meta‐analysis employed a multilevel modeling approach to synthesize fluency–proficiency relationships from 71 empirical studies from 1959–2023. Additionally, we examined several moderator variables, including task type, learning context, age, and proficiency measure. The correlations found were strongly positive for speed ( r = .55), moderately positive for productivity ( r = .38), moderately negative for breakdown ( r = −.33), and weakly negative for repair ( r = −.11). Moderator analyses revealed that task, learning context, and proficiency measure influence fluency–proficiency relationships in the repair, productivity, and speed dimensions, respectively. Post hoc analyses also suggested that the operationalization of breakdown features might make a difference in fluency–proficiency relationships. This study has both theoretical and methodological implications for second language fluency research.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
