Abstract

fetched live from OpenAlex

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
