Perception versus Production in Korean L 2 Acquisition of English Sibilant Fricatives

An important question in the L2 acquisition of phonemic distinctions is whether learners have to perceive contrasts before they can successfully produce them. In this paper, data on both the perception and production of the English /s/-/š/ contrast were elicited from native speakers of Korean, a language in which [s] and [š] are allophones of the same phoneme. General principles of phonology predict that, in acquiring this contrast, Korean learners will suppress the application of the allophonic rule relating these sounds across a morpheme boundary only if they can prevent the rule from applying within morphemes. This study examines these predictions in both production and perception of the /s/-/š/ contrast as a function of learner’s training.
