Articulatory and perceptual cues to non-native phoneme perception: Cross-modal training for early learners

Non-native phoneme perception can be challenging for adult learners. This article explores two routes to strengthening early representations of non-native targets: perceptual training, which focuses on auditory discrimination of novel contrasts, and articulatory training, which highlights the articulatory gestures of non-native categories. Of particular interest is whether cross-modal transfer from production to perception is beneficial to improving discrimination. A longitudinal experiment integrating both training types found that articulatory training did not improve discrimination once perceptual learning had taken place. However, a follow-up experiment found an equivalent benefit for perceptual and articulatory training when each was presented as the only learning style to separate groups of learners. These findings suggest that articulatory learning can 'cross over' to assist acquisition in the perceptual domain, and may play a key role for second language (L2) learners struggling with both perception and production of novel phoneme categories.
