This study examines the acoustic interactions between vowel duration and intensity depending on the position of adverbs in phrasal verbs in English for Korean and American speakers. Vowel duration and intensity among types of adverbs are significantly different for American speakers. Vowel duration and intensity are greater for adverbs following nouns (T3) than for adverbs preceding nouns (T1, T2). With regard to vowel duration and intensity between nouns and adverbs, it turns out that the parameters are inversely proportional to the location of adverbs and nouns. There are no significant differences in the intensity of adverbs and nouns produced by Korean speakers, only in vowel duration. This comes to the point that the main effect on vowel duration and intensity depend on the position of adverbs in the case of American speakers. On the other hand, Korean speakers only indicate strengthening of vowel duration depending on the location of adverbs. These results indicate that it is necessary to teach the degree of phonetic reinforcement for conveying meaning depending on the position of adverbs in phrasal verbs.
