This study investigates and compares the effects of different training paradigms in both the perception and production of English /I/ and /i:/ by Cantonese-speaking ESL learners. A total of 39 subjects participated in this study, in which 9 were trained under the High Variability Phonetic Training (HVPT) approach (H group), 11 under explicit articulation training (P group), 9 under a combination of both (HP group) whereas 10 as the control group (C group). Only the H and HP groups, the two groups receiving the HVPT, showed significant perceptual learning and generalization to new words and new speakers. The P group which received productive training only had no significant learning in the perceptual domain. Yet, robust improvement in production was observed in all three treatment groups, with the HP group significantly outperforming the other two training groups. The HP group was also the only one group that transferred the learning at word level to sentence level during a passage reading task. The results suggest that perceptual learning can be transferred to the production domain, but mere productive training barely improves perception. Training effectiveness can also be enhanced when training in both domains are provided.
