This paper is an aerodynamic study of the nasals and vowel nasalization in Hong Kong Cantonese (HKC) by analyzing synchronized nasal and oral airflows. The nasal airflow volume for the vowels in both oral and nasal contexts and for the syllable-final nasals [-m, -n, -η] were obtained. Results show that (i) the nasal airflow volume for the nasalized vowels in the (C)V:N and (C)VN syllables is positively correlated with the vowel duration and inversely correlated with the vowel height; (ii) the degree of contextual nasalization for the vowel depends on the vowel type as well as the nasal type in the (C)V:N and (C)VN syllables; (iii) the total nasal airflow volumes for the 3 nasal consonants vary substantially; and (iv) a relatively smaller nasal airflow volume is observed for the nasals and for the nasalized vowels associated with a low falling tone 21.
