A forced-choice test on American English vowel perception was administered to 10 university-level Korean talkers. The stimuli consisted of 148 CV sequences in which 9 vowels were presented in 18 onset consonant environments. After listening to 1480 presentations across 5 blocks, the subject was forced to click on one of 9 vowel icons on the computer screen. Statistical analyses were conducted on the resulting data. It was found that American English back vowels were more difficult for Korean talkers to identify than front vowels whereas American English mid vowels were more difficult than high and low vowels.
