Perception and production of English stops by tonal and non-tonal Korean dialect speakers

This study examines whether relative weightings of voice onset time and onset F0 in Korean tonal vs non-tonal dialects affect the production and perception of English voiced and voiceless stops. Following Shultz et al. [(2012). J. Acoust. Soc. Am. 132, EL95-EL101], discriminant function analysis and logistic regression were conducted to calculate each speaker's relative weightings of these two cues in the production of target words and the labeling of the synthesized tokens according to these cues, respectively. The results demonstrated that the acquisition of second language (L2) contrasts is influenced by native language dialects, and production and perception are not developed in parallel in L2 acquisition.
