Effects of EPG treatment for English consonant contrasts on L2 perception and production

Links between perception and production were investigated for two adult native speakers of Korean who participated in electropalatographic (EPG) treatment designed to teach phonological and articulatory contrasts between English /s/ - /ʃ/, /z/ - /ʤ/, and /l/ - /ɹ/. Participants were successful in learning to produce the English contrasts. Perception of English consonants was tested pre- and post-treatment. Post-treatment perception improved somewhat for treated consonants but not for untreated consonants, although perception was not directly trained.
