Native English speakers were trained to identify Japanese vowel length with sentences spoken at a fast rate, and their test scores before and after training were compared with those of a control group. Results indicated that the present training with little variability in speaking rate did not yield a robust perceptual improvement for the trained group. However, among the three rates tested (slow, normal, fast), the trained group showed significant improvement specifically for the slow-rate stimuli, distinct from the control groupís.
