Rio de Janeiro

Brazilian Portuguese keeps every vowel that Lisbon whispers away, which makes it sound like a different language at first. t and d hiss before i — 'dia' is 'jia' — a final l is a w, and Rio specifically turns the r of 'rio' and the r at the end of a word into a breath. The ʃ on final s is one of the few things Rio shares with Lisbon.

Where: Brazil — carioca

The way in: 'Bom dia, Rio' as bõ d͡ʒia hiu.

Rio de Janeiro

Which rules fired

  1. Final unstressed e is a full i
  2. t hisses before i

Melody and rhythm

Syllable-timed where Lisbon is stress-timed: every vowel gets its beat, so the language sounds sung. Rio adds a long, lazy rise on stressed syllables and a rising tail on questions.

What moves, one rule at a time

In the order the mouth applies them. Every before-and-after is playable — click the IPA. The pattern is the rule as the engine runs it, for the curious.

Consonants

t hisses before i

t(?=[iɪ]) → t͡ʃ

When: before i, including the i that a final e has just become

How: Let the t release into the ch of 'church'.

'Tia' is 'chia', 'noite' is 'noichi'. It is the most Brazilian sound there is, and Lisbon does not have it at all.

gente

d hisses before i

d(?=[iɪ]) → d͡ʒ

How: 'Dia' is 'jia' — the j of English 'jeep'.

WordReferenceAccent
dia
verde
cidade

l at the end of a syllable is a w

l(?=[pbtdkɡqʔmnɲŋɴfvθðszʃʒɕʂʐçxχɣʁħʕhβʝlʎɹrɾjwɥʈɖɳɽʋɦ]|$| ) → w

How: Say 'oo' where the l would be.

Which is why 'Brasil' ends in the sound of 'ow'. Lisbon keeps a dark l.

The strong r is a breath

ʁ → h

How: Just breathe. No tongue, no throat.

Rio's r is the English h. 'Rio' is 'hee-oo'.

WordReferenceAccent
rio
carro
rua

…and so is r at the end of a word

ɾ$ → h

When: at the end of a word; very often it drops away entirely

comer
falar

Vowels

Final unstressed e is a full i

ɨ → i

How: Say a full 'ee'. Every syllable is pronounced.

Brazil never reduced this vowel. It is a clear i — and that i then triggers the next rule.

WordReferenceAccent
sete
noite
verde

Unstressed a is a full a

ɐ(?![̃]) → a

Lisbon reduces it to a schwa-like ɐ. Brazil says the vowel.

mesa
