For example, non-syllabic nasal consonants are always followed by a nasal vowel, and syllabic nasal consonants are analyzed as reduced forms of consonantvowel syllables.
It tends to be nasalized before a nasal vowel, with the nasality spreading to preceding vowels: to run has been recorded as.
The result of this change was the same: a long nasal vowel.
Depending on the phonetic environment, the nasal vowel may vary between and, whereas may vary from to.
But the obvious advantage is that we obtain a rapid visual diachronic overview of the evolution of the nasal vowel pronunciation in the course of the past decades.
Perceptual constraints and phonological change : a study of nasal vowel height.
These contour segments would have to be derived by some type of nasal spreading that allows nasality to ' leak ' from a nasal vowel to a following obstruent.
The lexical and grammatical factors included the word in which the nasal vowel occurred; the word's frequency; and the word's grammatical class.
