Only three sounds in English use Nasal Resonance.: "m," "n," and "ng."
The only three nasal phonemes in English are: "m" as in "mam," "n" as in "non," and "ng" as in "ãbong."
If you prolong those three sounds while placing your fingers on the side of your nose, you can feel the resonance. Try it and then alternate making a non nasal sounds (i.e., any vowel or other consonant).
Although there are only three nasal phonemes, they occur in speech with an especially high frequency.
Sometimes if a childâs movement of the velum is sluggish, the sounds on either side of a nasal phoneme may also acquire a nasal resonance. This is called assimilation, and would occur in a word like, "man;" but not in "pat."
When vowels are nasalized, they are still recognizable, although the resonance may sound a little whiney.
