A1 (Beginner)Lesson 7: Sounds of Brazilian Portuguese
Portuguese has seven stressed oral vowel sounds. All seven are pure vowels, but the letters E and O each represent two sounds — an open one and a closed one — and the difference can change a word’s meaning.
Five vowel letters, seven stressed oral sounds: a, e (open/closed), i, o (open/closed), u
/a/ [a] = open, like "ah" in "father"
/e/ closed [e] = like "ay" in "say" (no glide)
/ɛ/ open [ɛ] = like "e" in "bed"
/i/ [i] = like "ee" in "see"
/o/ closed [o] = like "o" in "go" (no glide)
/ɔ/ open [ɔ] = like "aw" in "law"
/u/ [u] = like "oo" in "food"
five vowel letters → seven stressed oral sounds · é/ó (oral vowels) = open, ê/ô = closed · final unstressed -e → [i], -o → [u] in many Brazilian varieties

Get a vowel wrong and you might call your avó (grandma) an avô (grandpa), or say jogo "I play" when you mean jogo "game." Portuguese open/closed vowels separate word pairs, so they're not a fine detail — they're the difference between being understood and getting a confused look. The good news: most of it sticks through imitation, and the written é/ó and ê/ô identify the open or closed vowel.
Here’s the good and the bad news about Portuguese vowels. Good news: all seven stressed oral vowels are pure — a single vowel sound, without a glide (Portuguese só has open [ɔ], without the English glide in so). Bad news: the letters E and O each hide two sounds — an open one and a closed one — and the difference can flip a word's meaning (avô = grandpa, avó = grandma). Don't panic: your ear absorbs most of this by imitation. This lesson is just the map.
The comparisons below are approximate; focus on the stressed vowel in each example, not its duration.
| Letter | Sound | IPA | Like… | Examples |
|---|---|---|---|---|
| A | open /a/ | [a] | "ah" in father | casa, falar, água |
| E | closed /e/ | [e] | "ay" in say (no glide) | você, mês, dedo |
| E | open /ɛ/ | [ɛ] | "e" in bed | café, pé, festa |
| I | /i/ | [i] | "ee" in see | filho, isto, livro |
"Eu e você" (often [i]; [e] also occurs regionally) — me and you
"Ele é brasileiro" (closed [e], then open [ɛ]) — He is Brazilian
"Quero um café" (both open [ɛ]) — I want a coffee
"Moro em Porto Alegre" (open [ɔ] in moro, closed [o] in Porto) — I live in Porto Alegre
"Posso entrar?" (open [ɔ]) — Can I come in?
"A porta está aberta" (open [ɔ]) — The door is open
These transcriptions show common Brazilian pronunciations; vowel raising, T/D affrication and R pronunciation vary regionally.
An m/n closing a syllable usually marks a nasal vowel. Before m/n/nh beginning the next syllable, nasalization depends on the word, stress and variety; it does not happen automatically before every nasal consonant.
tempo, sempre, onde, sonho (see the nasal-sounds lesson)
Borrowed words can adapt to Brazilian pronunciation; they are not blanket exceptions to final-vowel raising.
internet may acquire a final [i]; shopping varies; hotel ends in L, so the final -e/-o rule does not apply.
The same verb can open or close the vowel as it conjugates:
eu posso [ɔ] (I can), ele pode [ɔ] (he can) vs. ele pôde [o] (he could)
eu gosto [ɔ] (I like) vs. o gosto [o] (the taste)
Why do Portuguese e and o have open and closed stressed sounds? The distinction developed from the Latin vowel system as vowel length lost its contrastive role. Short Latin e/o generally became open; long e/o generally became closed, alongside other mergers. Later sound changes and analogy also affected individual words: avô/avó is not simply a preserved Latin long-o/short-o pair.
