The purpose of this study is to compare voicing contrast in the onset of stop sounds and the similarities/differences between American and Korean speakers in onsets and codas which Koreans often have a tendency to substitute for other similar sounds in their pronunciations. The first experiment is launched to measure the VOT value of stop sounds in American and Korean students’ pronunciations. The second experiment is done to measure the Formants frequency and Bandwidths of sounds in vowels with onsets or codas of words. Based on their measurements, I have compared LPC (linear predictive coding) distance values between the speakers of the two groups, and have also analyzed DTW (dynamic time warping) distance values in order to compare the matching degree in whole words of American and Korean speakers one by one. The third experiment is a listening evaluation task of foreign teachers judging Korean subjects. The last experiment is a listening test for sound recognition ability of other Korean groups when they listen to two similar sounds. The experimental analyses show that Korean speakers exhibit a difference in pronunciation from American speakers in voiceless stops, but not in voiced ones in VOT value. For a comparison of the similarities and differences of onsets and codas, the best matches in LPC and DTW show differences in the voicing contrast of fricatives/stops, that is, in LPC, voiced stops and fricatives obtain the best matches, while in DTW, voiceless stops and fricatives get the best matches. The listening evaluation task of foreign teachers shows that Koreans pronounce the words in onset position well, but still have problems with voicing in codas. Finally, in the Korean students’ listening test, because 41% failed to distinguish between a voiced fricative and a stop in the coda position, this shows that Koreans still have more difficulty in recognizing sounds in coda positions than in onset.
