This paper reports on an attempt to synthesize two different Korean syllables based on the previous articulatory and acoustic studies about Korean stops: /t'a/ which consists of an alveolar fortis stop and /ta/ which consists of an alveolar lenis stop. Using these two synthesized syllables as endpoints of the continuum, five more syllables between two endpoints were created for identification and discrimination tasks. Korean native speakers did not perceive the stimuli categorically; their identification boundary was not very sharp and the discrimination peak was not very high, either. Two possible reasons were proposed for this unexpected result.
