Abstract
Abstract In order to investigate the characteristics and effects of peer feedback targeting second language (L2) pronunciation, the present study recruited 32 Mandarin-speaking learners of English who received five pronunciation instructional sessions through an instant messaging application on their smart phones. The phonological targets, types, and formats of peer feedback as well as its effects on their pronunciation (i.e., comprehensibility and accentedness) were examined. Results revealed that the participants mainly targeted segmental errors rather than suprasegmental errors and that they tended to provide more feedback on vowels rather than on consonants. Their feedback, delivered mainly in writing, was found to be effective in improving learners’ comprehensibility, but not their accentedness. The findings demonstrate the potential of peer feedback complementary to teacher feedback in instructed L2 pronunciation and highlight the importance of training in optimizing the effectiveness of peer feedback.

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
