Production and perceptual discrimination of vowels in /h-v-d/ syllables (based on Peterson & Barney, 1952) were recorded and analyzed. The accuracy of perceptual judgment was calculated. The major findings are: 1) In both production and perception, there are much more errors in lax vowels than those of tense vowels; 2) Vowel / /, in both production and perception data, occupies around 50% of all the errors. 3) In both perception and production data, vowels / /and / / show high percentages of total errors. The major error patterns are the substitution or confusion of this vowel pair; 4) In both perception and production, front vowels perform better than back vowels. The findings reflect the idea of the influence from speakers native language (Bosch, Costa, & Sebastian-Galles, 2000). Moreover, the learners tend to blend similar vowels in L2 and L1, as mentioned in Weinreich s study (1968) that learners attend to similarities rather than differences between two sound systems. Keywords: vowel perception, vowel production, language interference 1
