Nasal vowel
A nasal vowel is a vowel that is produced with a lowering of the soft palate (or velum) so that the air flow escapes through the nose and the mouth simultaneously, as in the French vowel /ɑ̃/ (ⓘ) or Amoy [ɛ̃]. By contrast, oral vowels are produced without nasalization.
Nasalized vowels are vowels influenced by nearby sounds. For instance, the [æ] of the word hand in English is affected by the following nasal consonant. In most languages, vowels adjacent to nasal consonants are produced partially or fully with a lowered velum in a natural process of assimilation and are therefore technically nasal, but few speakers would notice. That is the case in English: vowels preceding nasal consonants are nasalized, but there is no phonemic distinction between nasal and oral vowels, and all vowels are considered phonemically oral.
Some languages contrast oral vowels and nasalized vowels phonemically. Linguists make use of minimal pairs to decide whether or not the nasality is of linguistic importance. In French, for instance, nasal vowels are distinct from oral vowels, and words can differ by the vowel quality. The words beau /bo/ "beautiful" and bon /bɔ̃/ "good" are a minimal pair that contrasts primarily the vowel nasalization even though the /ɔ̃/ from bon is slightly more open.
Portuguese allows nasal diphthongs, which contrast with their oral counterparts, like the pair mau /ˈmaw/ "bad" and mão /ˈmɐ̃w̃/ "hand".
Although there are French loanwords in English with nasal vowels like croissant [ˈkɹwɑːsɒ̃], there is no expectation that an English-speaker would nasalize the vowels to the same extent as French-speakers or Portuguese-speakers. Likewise, pronunciation keys in English dictionaries do not always indicate nasalization of French or Portuguese loanwords.
Nasalization as a result of the assimilation of a nasal consonant tends to cause a raising of vowel height; phonemically distinctive nasalization tends to lower the vowel. According to a different assessment, high vowels do tend to be lowered, but low vowels tend to be raised instead.
In most languages, vowels of all heights are nasalized indiscriminately, but preference occurs in some languages, such as for high vowels in Chamorro and low vowels in Thai.
A few languages, such as Palantla Chinantec, contrast lightly nasalized and heavily nasalized vowels. They may be contrasted in print by doubling the IPA diacritic for nasalization: ⟨ẽ⟩ vs ⟨ẽ̃⟩. Bickford & Floyd (2006) combine the tilde with the ogonek: ⟨ẽ⟩ vs ⟨ę̃⟩. (The ogonek is sometimes used in an otherwise IPA transcription to avoid conflict with tone diacritics above the vowels.)
