Abstract
Abstract This study investigated the effects of task complexity on the linguistic dimensions of comprehensibility and perceived fluency in L2 Japanese. 36 Chinese-speaking learners of Japanese performed two argumentative speech tasks with differing levels of complexity. These audio samples were judged by eight experienced native raters of Japanese for comprehensibility and perceived fluency and then analyzed in terms of complexity, accuracy, and fluency. The results showed that linguistic correlates of comprehensibility exhibit a task-specific effect, with additional linguistic dimensions (e.g., syntactic density, explicit grammatical marking) becoming increasingly relevant as task complexity rises. In contrast, perceived fluency also undergoes a task-specific shift but differently: rather than expanding the set of predictors, it changes the nature of primary cues, placing greater emphasis on syntactic sophistication alongside (but not replacing) temporal aspects. Findings underscore the unique role of Japanese linguistic system in shaping listeners’ judgments of L2 Japanese.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
