Changes in group means and 95% confidence intervals for L2 prosodic proficiency over time (T1 vs. T2), comparing the normative auditory precision group (red) and the lower auditory precision group (blue). The prosodic proficiency in the normative precision group remained consistent over time; however, there was a significant reduction in proficiency among those with lower auditory precision, resulting in significantly lower scores than those of the normative group at the project's end (T2).
