Discussion
Counterexamples
Languages in which there are no phonemic nasal vowels but denasalization of nasal consonants occurs include Asmat, Cantonese, Cham, Diegueno, Korean, and Telefol. However, such denasalization occurs either preconsonantally (as epenthetic stops in English), before high vowels, or after long vowels. Intervocalic denasalization not specifically conditioned by quality or length of the adjacent vowel, then, seems to be limited to languages with distinctive nasal vowels, as Hyman predicted.
