Abstract
Abstract Despite growing interest in the role of prosody in communication, there is still a need for more empirical research to better understand its impact on listeners’ understanding and to provide effective pronunciation instruction. The study compares the effectiveness of two methods (i.e., embodied and computer-assisted techniques) in training Japanese vowel length contrast and pitch accent, with the aim of improving L2 perception and production, and ultimately increasing intelligibility and comprehensibility. Training was provided to English-speaking learners of Japanese for four weeks. Following the training, learners exhibited significant improvement in their overall performance, and these observed improvements often continued until the delayed posttest. Furthermore, there were no significant differences in performance between learners assigned to embodied techniques and those using computer-assisted methods. These findings suggest that both methods may be equally effective and that L2 prosody can improve in as short as four weeks with targeted instruction.

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
