This article represents a first step in a large study aimed at elucidating the relationship between production and perceptioninvolved in sound change of /o/ in (Seoul) Korean. In this paper we present the results of a production study and aperception experiment. For the production study we examined vowel production data of 20 young adult speakers, measuringthe first and second formants, then conducted a discriminant analysis based on those values. In terms of their F1-F2 values,the distribution of /o/ and /u/ were close, and even overlapping in some circumstances, which is consistent with the literature. This tendency was more apparent among the female speakers than the males. Moreover, with the females' distributions, /o/was frequently categorized as /u/, suggesting that the direction of the sound change is indeed increasing from /o/ to /u/. Next,to investigate the effects of this proximity on perception, we used the production data of five randomly selected speakersfrom the production study as stimuli for a perception experiment in which 21 young adult native speakers of (Seoul) Koreanperformed a vowel identification task and provided a Goodness rating on a 5-point scale. We found that while rates ofcorrectness were high, when these correctness scores were weighted by the Goodness rating, these “weighted correctness”scores were lower in some cases, indicating a degree of confusion in distinguishing between the two vowels.
