The /e-ɛ/ and /o-ɔ/ distinction does not happen in nasal vowels; ⟨em om⟩ are pronounced as close-mid. In BP, the vowel (which the letter ⟨a⟩ otherwise represents) is sometimes phonemically raised to when it is nasal, and also in stressed syllables before heterosyllabic nasal consonants (even if the speaker does not nasalize vowels in this position): compare for instance "dama sã" (PT) or (BR) ('healthy lady') and "dá maçã" (PT) or (BR) ('it gives apples'). may also be raised slightly in word-final unstressed syllables.
