This paper presents a comparative analysis between English-by-Natives and English-by-Koreans with %C, stressed or unstressed vowels, and speech rate(syllables/second). First, the %C of a sentence was lower in English-by-Koreans than in English-by-Natives. Its reason is that the vowel duration of English-by-Koreans was longer than that of English- by-Natives, particularly in unstressed vowels. Second, the duration gap between an unstressed vowel and a stressed vowel was greater in English-by-Natives than in English-by-Koreans. It means that stress did not influence the duration of stress or unstress vowel in English-by- Koreans as much as in English-by-Natives. Third, the coefficient of inverse correlation between consonants and speech rate was higher in English-by- Koreans than in English-by-Natives. For English-by- Koreans, unstressed vowels were more strongly influenced by speech rate than stressed vowels.
