Nasality

 

a shade of the voice and a distorted pronunciation of the sounds of speech caused by the peculiarities of the sound-forming stream of air as it passes through the nasal and oral cavities. There are open and closed forms of nasality.

Open nasality is observed in cases of defects of the hard palate and defects and paralysis of the soft palate when a significant part of the air passes into the nose during the pronunciation of the sounds of speech—the voice acquires a severe nasal shade, and speech becomes inarticulate. Closed nasality arises as a consequence of the difficult passage of air through the nose as a result of chronic cold, adenoids, or polypi in the nose; this especially disrupts the pronunciation of the nasal sounds [m] and [n]—they sound like [b] and [d], and the voice becomes muted. Sometimes nasality is caused not by an anatomical problem but by a habit of incorrectly pronouncing words, in particular as a result of deafness and consequent inability to aurally check the speech. Nasality can be eliminated by special logopedic exercises. If anatomical problems are present, preparatory treatment, sometimes surgery, is conducted.

Maisuradze seems to have developed more of an open-throated tenor since his last collaboration with the COC as Des Grieux in Manon Lescaut, though a nasality still creeps in when he pushes the volume.
In examples (10) and (11) from Hindi the fixed vowel matches the corresponding base vowel in length and, in the latter case, also nasality.
cnaa (see [11] above) also seems to illustrate the prespecification of a subset of distinctive features: here the vowel quality changes, but not its nasality.
Here, we see a case of overapplication: nasality spreads from nasals to vowels in unexpected positions in order to preserve identity between paradigmatically related forms such as the singular and plural forms of verbs.
Normally the spreading of nasality of a nasal onto the following vowels is stopped by oral consonants and glides, but in the plural form nasality is spread across the/1/, thus creating a larger degree of identity between the singular and the plural form.
McCarthy and Prince (1995) suggest that nasality on vowels may be absent from the underlying forms, since its distribution is predictable: nasality "spreads" rightward until encountering an oral stop (transcription has been changed to IPA).
