The phonology of Portuguese can vary between dialects, in extreme cases leading to some difficulties in intelligibility. This article focuses on the pronunciations that are generally regarded as standard. Since Portuguese is a pluricentric language, and differences between European Portuguese (EP) and Brazilian Portuguese (BP) can be considerable, both varieties are distinguished whenever necessary.
One of the most salient differences between European and Brazilian Portuguese is their prosody. European Portuguese is a stress-timed language, with reduction, devoicing or even deletion of unstressed vowels and a general tolerance of syllable-final consonants. Brazilian Portuguese, on the other hand, is of mixed characteristics, and varies according to speech rate, dialect, and the gender of the speaker, but generally possessing a lighter reduction of unstressed vowels, less raising of pre-stress vowels, less devoicing and fewer deletions. At fast speech rates, Brazilian Portuguese is more stress-timed, while in slow speech rates, it can be more syllable-timed. The accents of rural, southern Rio Grande do Sul and the Northeast (especially Bahia) are considered to sound more syllable-timed than the others, while the southeastern dialects such as the mineiro, in central Minas Gerais, the paulistano, of the northern coast and eastern regions of São Paulo, and the fluminense, along Rio de Janeiro, Espírito Santo and eastern Minas Gerais as well the Federal District, are most frequently essentially stress-timed. Also, male speakers of Brazilian Portuguese speak faster than female speakers and speak in a more stress-timed manner.
Brazilian Portuguese disallows some closed syllables: coda nasals are deleted with concomitant nasalization of the preceding vowel, even in learned words; coda /l/ becomes [w], except for conservative velarization at the extreme south and rhotacism in remote rural areas in the center of the country; the coda rhotic is usually deleted entirely when word-final, especially in verbs in the infinitive form; and /i/ can be epenthesized after almost all other coda-final consonants. This tends to produce words almost entirely composed of open syllables, e.g., magma [ˈmaɡimɐ]. In European Portuguese, similarly, epenthesis may occur with [ɨ], as in magma [ˈmaɣɨmɐ] and afta [ˈafɨtɐ].

The consonant inventory of Portuguese is fairly conservative. The medieval Galician-Portuguese system of seven sibilants (/ts, dz/, /ʃ ʒ/, /tʃ/, and apicoalveolar /s̺ z̺/) is still distinguished in spelling (intervocalic c/ç z x g/j ch ss -s- respectively), but is reduced to the four fricatives /s z ʃ ʒ/ by the merger of /tʃ/ into /ʃ/ and apicoalveolar /s̺ z̺/ into either /s z/ or /ʃ ʒ/ (depending on dialect and syllable position), except in parts of northern Portugal (most notably in the Trás-os-Montes region). These changes are known as deaffrication. Other than this, there have been no other significant changes to the consonant phonemes since Old Portuguese. However, several consonant phonemes have special allophones at syllable boundaries (often varying quite significantly between European and Brazilian Portuguese), and a few also undergo allophonic changes at word boundaries. Henceforward, the phrase "at the end of a syllable" can be understood as referring to a position before a consonant or at the end of a word.
- Semivowels contrast with unstressed high vowels in verbal conjugation, as in (eu) rio /ˈʁi.u/ 'I laugh' and (ele) riu /ˈʁiw/ 'he (has) laughed.'  Phonologists discuss whether their nature is vowel or consonant. In intervocalic position semivowels are amibisyllabic, they are associated to both previous syllable and to the next syllable onset.
- In some of Brazil and Angola, the consonant hereafter denoted as /ɲ/ is realized as a nasal palatal approximant [j̃], which nasalizes the vowel that precedes it: ninho [ˈɲĩj̃u ~ nʲĩj̃u] 'nest'. Conversely, [ɲ ~ nʲ] is often the pronunciation of a sequence of /n/ followed by /i/ in a rising diphthong in Brazil, forming a minimal pair between sonha [ˈsõj̃ɐ] and Sônia [ˈsõɲɐ ~ ˈsõnʲɐ].
- The consonant hereafter denoted as /ʁ/ has a variety of realizations depending on dialect. In Europe, it is typically a uvular trill [ʀ]; however, a pronunciation as a voiced uvular fricative [ʁ] may be becoming dominant in urban areas. There is also a realization as a voiceless uvular fricative [χ], and the original pronunciation as an alveolar trill [r] also remains very common in various dialects. A common realization of the word-initial /r/ in the Lisbon accent is a voiced uvular fricative trill [ʀ̝]. In Brazil, /ʁ/ can be velar, uvular, or glottal and may be voiceless unless between voiced sounds; it is usually pronounced as a voiceless velar fricative [x], a voiceless glottal fricative [h] or voiceless uvular fricative [χ]. See also Guttural R in Portuguese.
- /s/ and /z/ are normally lamino-alveolar, as in English. However, a number of dialects in northern Portugal pronounce /s/ and /z/ as apico-alveolar sibilants (sounding somewhat like a soft [ʃ] or [ʒ]), as in the Romance languages of northern Iberia. A very few northeastern Portugal dialects still maintain the medieval distinction between apical and laminal sibilants (written s/ss and c/ç/z, respectively).
- As phonemes, /tʃ/ and /dʒ/ occur only in loanwords (e.g tchau and dee jay), with a tendency for speakers to substitute into fricatives in Portugal. However, [tʃ] and [dʒ] are allophones of /t/ and /d/ before front high vowels in most Brazilian dialects.
- In northern and central Portugal, the voiced stops /b/, /d/, /ɡ/ are usually lenited to fricatives [β], [ð], and [ɣ] respectively, except at the beginning of words, or after nasal vowels; a similar process occurs in Spanish.
- In large parts of northern Portugal, e.g. Trás-os-Montes, /b/ and /v/ are merged, both pronounced /b ~ β/, as in Spanish.
There is a variation in the pronunciation of the first consonant of certain clusters, most commonly C or P in cç, ct, pç and pt. These consonants may be variably elided or conserved. For some words, this variation may exist inside a country, sometimes in all of them; for others, the variation is dialectal, with the consonant being always pronounced in one country and always elided in the other. This variation affects 0.5% of the language's vocabulary, or 575 words out of 110,000. In most cases, Brazilians variably conserve the consonant while speakers elsewhere have invariably ceased to pronounce it (for example, detector in Brazil versus detetor in Portugal). The inverse situation is rarer, occurring in words such as fa(c)to and conta(c)to (consonants never pronounced in Brazil, pronounced elsewhere). Until 2009, this reality could not be apprehended from the spelling: while Brazilians did not write consonants that were no longer pronounced, the spelling of the other countries retained them in many words as silent letters, usually when there was still a vestige of their presence in the pronunciation of the preceding vowel. This could give the false impression that European Portuguese was phonologically more conservative in this aspect, when in fact it was Brazilian Portuguese that retained more consonants in pronunciation.
Syllables have the maximal structure of (C)(C)V(C). The only possible codas in European Portuguese are [ʃ], [ɫ] and /ɾ/ and in Brazilian Portuguese /s/ and /ɾ~ʁ/.
- The consonants /ʎ/ and /ɲ/ only occur in the middle of a word between vowels, and only rarely occur before /i/.
- Although nasal consonants do not normally occur at the end of syllables, syllable-final /n/ may be present in rare learned words, such as abdómen ([ɐbˈdɔmɛn] 'abdomen'). In Brazilian varieties, these words have a nasal diphthong ([abˈdõmẽj], spelled as abdômen). Word-initial /ɲ/ occurs in very few loanwords.
- While the sibilant consonants (/s z ʃ ʒ/) contrast word-initially and intervocalically, they appear in complementary distribution in the syllable coda. For many dialects (i.e., those of Portugal and of Rio de Janeiro and certain adjoining areas in Brazil), the sibilant is a postalveolar in coda position (e.g., pasto [ˈpaʃtu] 'pasture'; -ismo [ˈiʒmu] '-ism'; paz [pa(ʲ)ʃ] 'peace'). In many other dialects of Brazil (e.g., some of the Southeast, Northeast, and North), the postalveolar variant occurs in some or all cases when directly preceding a consonant, including across word boundaries, but not word-finally (e.g., [ˈpaʃtʊ ~ ˈpastʊ], [ˈiʒmʊ ~ ˈizmʊ], [pa(ʲ)s]). In a number of Brazilian dialects, this "palatalization" is absent entirely (e.g., [ˈpastʊ], [ˈizmʊ], [pa(ʲ)s]). Voicing contrast is also neutralized, with [ʒ] or [z] occurring before voiced consonants and [ʃ] or [s] appearing before voiceless consonants and before a pause (e.g., pasta [ˈpaʃtɐ] or [ˈpastɐ], 'paste'; Islão (or Islã) [iʒˈlɐ̃w̃] or [izˈlɐ̃], 'Islam'). In European dialects, the postalveolar fricatives are only weakly fricated in the syllable coda.
- The consonant /l/ is velarized [ɫ] in the syllable coda in European and most of African dialects. In most Brazilian dialects, /l/ is vocalized to [w] or [ʊ̯] at the end of syllables, but in the dialects of the extreme south, mainly along the frontiers with other countries (especially Uruguay), it has the full pronunciation or the velarized pronunciation.[clarification needed] In some caipira registers, there is a rhotacism of coda /l/ to retroflex [ɻ]. In casual BP, unstressed il can be realized as [ju], as in fácil [ˈfasju] ('easy').
- For speakers who realize /ʁ/ as an alveolar trill [r], the sequence /ʃr/ (as in e.g., os rins) can coalesce into a voiced alveolar fricative trill [r̝].
- Bisol (2005:122) proposes that Portuguese possesses labio-velar stops /kʷ/ and /ɡʷ/ as additional phonemes rather than sequences of a velar stop and /w/.
- The semivowels /j/ and /w/ do not occur before /i/ and /u/ respectively, and only contrast in some diphthongs like in pai [ˈpaj] versus pau [ˈpaw]. Otherwise they are the non-syllabic allophones of /i/ and /u/ in unstressed syllables.
- Unlike its neighbor and relative Spanish, Brazilian Portuguese lacks a tendency to elide any stop, including those that may become a continuant (always fricative in Portuguese) by lenition (/b/ > [β], /d/ > [ð], /ɡ/ > [ɣ]), but it has a number of allophones to it.
- In most Brazilian dialects, including the overwhelming majority of the registers of Rio de Janeiro (from where this process is said to have expanded to elsewhere in Brazil), other fluminense-speaking areas, and São Paulo, as well some rural areas of Portugal, the dental stops are affricated to [tʃ] and [dʒ] before /i/, /ĩ/. Post-alveolar affricates also appear in loanwords from languages such as English, Spanish, and Japanese (although it is common in Portugal to merge them with the post-alveolar sibilants, as was done with the former native affricate sounds in the Middle Ages).
The two rhotic phonemes /ʁ/ and /ɾ/ contrast only between oral vowels. Elsewhere, their occurrence is predictable by context, with dialectal variations in realization. The rhotic is "hard" (i.e., /ʁ/) in the following circumstances:
- Word-initially (e.g., rosa 'rose');
- Syllable-initially preceded by /l/ or /s/ (e.g., guelra 'gill', Israel);
- Following a nasal vowel (e.g., honrar 'to honor');
- In most Brazilian and some African dialects, syllable-finally (i.e., preceded but not followed by a vowel);
- When written with the digraph "rr" (e.g., carro 'car').
The realization of the "hard" rhotic /ʁ/ varies significantly across dialects.
This restricted variation has prompted several authors to postulate a single rhotic phoneme. Câmara (1953) and Mateus & d'Andrade (2000) see the soft as the unmarked realization and that instances of intervocalic [ʁ] result from gemination and a subsequent deletion rule (i.e., carro /ˈkaɾɾo/ > [ˈkaɾʁu] > [ˈkaʁu]). Similarly, Bonet & Mascaró (1997) argue that the hard is the unmarked realization.
In addition to the phonemic variation between /ʁ/ and /ɾ/ between vowels, up to four allophones of the "merged" phoneme /R/ are found in other positions:
- A "soft" allophone /ɾ/ in syllable-onset clusters, as described above;
- A default "hard" allophone in most other circumstances;
- In some dialects, a special allophone syllable-finally (i.e., preceded but not followed by a vowel);
- Commonly in all dialects, deletion of the rhotic word-finally.
The default hard allophone is some sort of voiceless fricative in most dialects, e.g., [χ] [h] [x], although other variants are also found. For example, a trill [r] is found in certain conservative dialects down São Paulo, of Italian-speaking, Spanish-speaking, Arabic-speaking, or Slavic-speaking influence. The other trill [ʀ] is found in areas of German-speaking, French-speaking, and Portuguese-descended influence throughout coastal Brazil down Espírito Santo, most prominently Rio de Janeiro.
The syllable-final allophone shows the greatest variation:
- Many dialects (mainly in Brasília, Minas Gerais and Brazilian North and Northeast) use the same voiceless fricative as in the default allophone. This may become voiced before a voiced consonant, esp. in its weaker variants (e.g., dormir [do̞ɦˈmi(h)] 'to sleep').
- The soft [ɾ] occurs for many speakers in Southern Brazil and São Paulo city.
- An English-like approximant [ɹ ~ ɻ] or vowel (R-colored vowel) occurs elsewhere in São Paulo as well as Mato Grosso do Sul, southern Goiás, central and southern Mato Grosso and bordering regions of Minas Gerais. This pronunciation is stereotypically associated with the rural "caipira" dialect.
Throughout Brazil, deletion of the word-final rhotic is common, regardless of the "normal" pronunciation of the syllable-final allophone. This pronunciation is particularly common in lower registers, although found in most registers in some areas, e.g., Northeast Brazil, and in the more formal and standard sociolect. It occurs especially in verbs, which always end in R in their infinitive form; in words other than verbs, the deletion is rarer and seems not to occur in monosyllabic non-verb words, such as mar. Evidence of this allophone is often encountered in writing that attempts to approximate the speech of communities with this pronunciation, e.g., the rhymes in the popular poetry (cordel literature) of the Northeast and phonetic spellings (e.g., amá, sofrê in place of amar, sofrer) in Jorge Amado's novels (set in the Northeast) and Gianfrancesco Guarnieri's play Eles não usam black tie (about favela dwellers in Rio de Janeiro).
The soft realization is often maintained across word boundaries in close syntactic contexts (e.g., mar azul [ˈmaɾaˈzuw] 'blue sea').
Portuguese has one of the richest vowel phonologies of all Romance languages, having both oral and nasal vowels, diphthongs, and triphthongs. A phonemic distinction is made between close-mid vowels /e o/ and the open-mid vowels /ɛ ɔ/, unlike in Spanish, though there is a certain amount of vowel alternation. European Portuguese has also two central vowels, one of which tends to be elided like the e caduc of French.
|Oral decreasing vowels|
|/ɛj/ (in Grande Lisboa, except by Setúbal [ɐj] )||/ɐˈnɛjʃ/||anéis|
|/ej/ (in Grande Lisboa, except by Setúbal [ɐj] )||/'sej/||sei|
|/ow/ (in most vernacular dialects: /o/)||/'sow/||sou|
|Nasal decreasing vowels|
|/ẽj̃/ (in Grande Lisboa, except by Setúbal [ɐ̃j̃])||/'bẽj̃/||bem|
|/õw̃/ (in most vernacular dialects: /õ/)||/'bõw̃/||bom|
Portuguese uses vowel height to contrast stressed syllables with unstressed syllables; the vowels /a ɛ e ɔ o/ tend to be raised to [ɐ e i ɨ o u] (although [ɨ] occurs only in EP) when they are unstressed (see below for details). The dialects of Portugal are characterized by reducing vowels to a greater extent than others. Falling diphthongs are composed of a vowel followed by one of the high vowels /i/ or /u/; although rising diphthongs occur in the language as well, they can be interpreted as hiatuses.
The exact realization of the /ɐ/ varies somewhat amongst dialects. In Brazil, [a] and [ɐ] are in complementary distribution: [ɐ ~ ə] occurs in word-final unstressed syllables, while [ɜ ~ ə] occurs in stressed syllables before an intervocalic /m/, /n/, or /ɲ/. In these phonetic conditions, [ɜ ~ ə] can be nasalized. Unstressed [a ~ ə] occurs in all other environments.
In European Portuguese, the general situation is similar (with [ə] being more prevalent in nearly all unstressed syllables), except that in some regions the two vowels form minimal pairs in some European dialects. In central European Portuguese this contrast occurs in a limited morphological context, namely in verbs conjugation between the first person plural present and past perfect indicative forms of verbs such as pensamos ('we think') and pensámos ('we thought'; spelled ⟨pensamos⟩ in Brazil). Spahr (2013:6) proposes that it is a kind of crasis rather than phonemic distinction of /a/ and /ɐ/. It means that in falamos 'we speak' there is the expected prenasal /a/-raising: [fɐˈlɐmuʃ], while in falámos 'we spoke' there are phonologically two /a/ in crasis: /faˈlaamos/ > [fɐˈlamuʃ] (but in Brazil both merge, falamos [faˈlɐmus]).
English loanwords containing stressed /ʌ/ or /ɜːr/ are usually associated with pre-nasal ⟨a⟩ as in rush, or are influenced by orthography as in clube (club), or both, as in surf/surfe.
Close-mid vowels and open-mid vowels (/e ~ ɛ/ and /o ~ ɔ/) contrast only when they are stressed. In unstressed syllables, they occur in complementary distribution. In Brazilian Portuguese, they are raised to a high or near-high vowel ([i ~ ɪ] and [u ~ ʊ], respectively) after a stressed syllable, or in some accents and in general casual speech, also before it.
European Portuguese possesses a near-close near-back unrounded vowel. It occurs in unstressed syllables such as in pegar [pɯ̽ˈɣaɾ] ('to grip'). There is no standard symbol in the International Phonetic Alphabet for this sound. The IPA Handbook transcribes it as /ɯ/, but in Portuguese studies /ɨ/ or /ə/ is traditionally used. There are very few minimal pairs for this sound: some examples include pregar [pɾɯ̽ˈɣaɾ] ('to nail') vs. pregar [pɾɛˈɣaɾ] ('to preach'; the latter stemming from earlier preegar < Latin praedicāre), sê [ˈse] ('be!') vs. sé [ˈsɛ] ('see/cathedral') vs. se [sɯ̽] ('if'), and pêlo [ˈpelu] ('hair') vs. pélo [ˈpɛlu] ('I peel off') vs. pelo [pɯ̽lu] ('for the'), after orthographic changes, all these three words are now spelled pelo.
European Portuguese possesses quite a wide range of vowel allophones:
- All vowels are lowered and retracted before /l/.
- All vowels are raised and advanced before alveolar, palato-alveolar and palatal consonants.
- Word-finally, /ɨ/ as well as unstressed /u/ and /ɐ/ are voiceless [ɯ̥̽, u̥, ə̥].
Diphthongs are not considered independent phonemes in Portuguese, but knowing them can help with spelling and pronunciation.
|Diphthong||Usual spelling||Example||Meaning||Notes and variants|
|/aj/||ai, ái||pai||'father'||In Brazil, it may be realized as [a] before a post-alveolar fricative /ʃ, ʒ/, making baixo realized as [ˈbaʃu].|
|/ɐj/||ai, âi||plaina||'jointer'||In Brazil, except Northern dialects. It occurs before nasal consonants and can be nasalised, as in plaina [ˈplɐjnɐ].|
|ei, éi, êi||leite||'milk'||In Greater Lisbon (according to NUTS III, which does not include Setúbal) /e/ can be centralized [ɐ] before palatal sounds (/j, ɲ, ʃ, ʒ, ʎ/); e.g. roupeiro [ʁoˈpɐjɾu], engenharia [ẽʒɐ(ʲ)ˈɲɐɾiɐ], texto [ˈtɐ(ʲ)ʃtu], vejo [ˈvɐ(ʲ)ʒu], coelho [kuˈɐ(ʲ)ʎu].|
|/ej/||ei, êi||rei||'king'||In several vernacular dialects (most of Portugal, Brazil and Lusophone Africa), "ei" may be realized essentially as [e] in unstressed syllables. Words ending on either -eiro or -eira (like roupeiro [ʁoˈpeɾu], bandeira [bɐ̃ˈdeɾɐ], brasileiro [bɾɐziˈleɾu], brasileira [bɾɐziˈleɾɐ], etc.), or in which -ei precedes a palatal sound (like queijo [ˈkeʒu], deixa [ˈdeʃɐ], etc.), are optionally monophthongized, depending on the speaker and region (comparable to Spanish ropero, bandera, brasilero, brasilera, queso, deja). In most stressed syllables, the pronunciation is /ej/. There are very few minimal pairs for /ej/ and /ɛj/, all of which occur in oxytonic words.
In Greater Lisbon, however, it is always pronounced [ɐj].
|/ɛj/||ei, éi||geleia, anéis||'jelly', 'rings'||In Portugal it only occurs in -el plurals like anéis (plural of anel 'ring').
In Greater Lisbon, however, it is always pronounced [ɐj].
|/ɔj/||oi, ói||dói, destrói||'hurts', 'destroys'||Pronounced as /ɔj/ mostly on -oi ending words like herói 'hero', as well as some verbal conjugations.|
|/uj/||ui||fui||'I went'||Usually stressed.|
|al||sal||'salt'||Phonemically /al/. It occurs only in BP; in Portugal, it is realized as a sequence [aɫ].|
|/ɐw/||au, âu||saudade||'to miss'||In EP, when unstressed. Also occurs in the contraction ao(s).|
|/ew/||eu, êu||seu||'his'||There are very few minimal pairs for /eu/ and /ɛu/, all occurring in oxytonic words.|
|el||mel||'honey'||Phonemically /ɛl/. It occurs only in BP; in Portugal, it is realized as a sequence [ɛɫ].|
|/iw/||iu||viu||'he saw'||Usually stressed.|
|il||mil||'thousand'||Phonemically /il/. It occurs only in BP; in Portugal, it is realized as a sequence [iɫ].|
|/ow/||ou||ouro||'gold'||Merges optionally with /o/ in most of modern Portuguese dialects (in all the Portuguese speaking world), excluding some regions in northern Portugal .|
|ol||polvo||'octopus'||Phonemically /ol/. It occurs only in BP; in Portugal, it is realized as a sequence [oɫ].|
|/ɔw/||sol||'sun'||Phonemically /ɔl/. It occurs only in BP; in Portugal, it is realized as a sequence [ɔɫ].|
|/uw/||ul||sul||'south'||Phonemically /ul/. It occurs only in BP; in Portugal, it is realized as a sequence [uɫ].|
|/wa/||ua||quase||'almost'||As the cases above, this and following cases are considered hiatus (unless they follow q or g) but pronounced as diphthongs.|
[j] and [w] are non-syllabic counterparts of the vowels /i/ and /u/, respectively. At least in European Portuguese, the diphthongs [ɛj, aj, ɐj, ɔj, oj, uj, iw, ew, ɛw, aw] tend to have more central second elements [i̠̯, u̟̯] - note that the latter semivowel is also more weakly rounded than the vowel /u/. In the Lisbon accent, the diphthong [ɐj] often has an onset that is more back than central, i.e. [ɐ̠j] or even [ʌj].
|Triphthong||Usual spelling||Example||Meaning||Notes and variants|
|/wej/||uei||averiguei||'I verified'||Realized as [wɐj] in Greater Lisbon.|
|/waw/||ual||qual||'which'||Phonemically /wal/. It occurs in Brazil; in Portugal, it is realized as a sequence [waɫ].|
|/wow/||uou||enxaguou||'(he/she) rinsed'||Usually pronounced as /wo/ in Central and Southern Portugal, as well as in Brazil.|
Portuguese also has a series of nasalized vowels. Cruz-Ferreira (1995) analyzes European Portuguese with five monophthongs and four diphthongs, all phonemic: /ĩ ẽ ɐ̃ õ ũ ɐ̃j̃ õj̃ ũj̃ ɐ̃w̃ õw̃/. Nasal diphthongs occur mostly at the end of words (or followed by a final sibilant), and in a few compounds. Brazilian Portuguese is overall [clarification needed] than European Portuguese due to many external influences including the common language spoken at Brazil's coast at time of discovery, Tupi.
|Nasal vowel||Usual spelling||Example||Meaning|
|/ɐ̃/||ã, am, an||rã, canto||'frog', 'I sing'|
|/ẽ/||em, en||entro||'I enter'|
|/ĩ/||im, in||vim||'I came'|
As in French, the nasal consonants represented by the letters ⟨m n⟩ are deleted in coda position, and in that case the preceding vowel becomes phonemically nasal, e.g. in genro /ˈʒẽ.ʁu/ ('son-in-law'). But a nasal consonant subsists when it is followed by a plosive, e.g. in cantar [kɜ̃nˈtaɾ] ('to sing'). Vowel nasalization has also been observed non-phonemically as result of coarticulation, before heterosyllabic nasal consonants, e.g. in soma [ˈsõ.mɐ] ('sum'). Hence, one speaks discriminatingly of nasal vowels (i.e. phonemically so) and nasalized vowels. Additionally, a nasal monophthong /ɜ̃/ written ⟨ã⟩ exists independently of these processes, e.g. in romã /ʀoˈmɜ̃/ ('pomegranade').
The /e-ɛ/ and /o-ɔ/ distinction does not happen in nasal vowels; ⟨em om⟩ are pronounced as close-mid. In BP, the vowel /a/ (which the letter ⟨a⟩ otherwise represents) is sometimes, phonemically raised to [ɜ] 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 [ˈdɐ.mɐ ˈsɐ̃] (PT) or [ˈdɜ̃.ma ˈsɜ̃] (BR) ('healthy lady') and dá maçã [ˈda mɐˈsɐ̃] (PT) or [ˈda maˈsɜ̃] (BR) ('it gives apples'). /a/ may also be raised slightly in word-final unstressed syllables.
Nasalization and height increase noticeably with time during the production of a single nasal vowel in BP in those cases that are written with nasal consonants ⟨m n⟩, so that /ˈʒẽ.ʁu/ may be realized as [ˈʒẽj̃.ʁu] or [ˈʒẽɰ̃.ʁu]. This creates a significant difference between the realizations of ⟨am⟩ and ⟨ã⟩ for some speakers: compare for instance ranço real [ˈʁɐ̃ɰ̃.su ˈʁjal] (PT) or [ˈʁɜ̃ɰ̃.su ʁeˈaw] (BR) ('royal rancidness') and rã surreal [ˈʁɐ̃.su ˈʁjal] (PT) or [ˈʁɜ̃.su ʁeˈaw] (BR) ('surreal frog'). (Here [ɰ̃] means a velar nasal approximant.) At the end of a word ⟨em⟩ is always pronounced [ẽj̃] with a clear nasal palatal approximant (see below). Whenever a nasal vowel is pronounced with a nasal coda (approximant or occlusive) the (phonetic) nasalization of the vowel itself is optional.
The following examples exhaustively demonstrate the general situation for BP.
- romã ('pomegranade') : [ʀoˈmɐ̃] : final vowel is (phonemically) "nasal" and nasal approximants may not be pronounced.
- genro ('son-in-law') : [ˈʒẽ.ʁu] or [ˈʒẽj̃.ʁu] or [ˈʒẽɰ̃.ʁu] : nasal consonant deleted; preceding vowel is (phonemically) "nasal" and nasal approximants may be pronounced.
- cem ('a hundred') : [ˈsẽj̃] : nasal approximant must be pronounced.
- cantar ('to sing') : [kɐ̃nˈtaɾ]: nasal consonant remains because of the following plosive; preceding vowel is raised and nasalized non-phonemically. (This is traditionally considered a "nasal" vowel by textbooks.)
- cano ('pipe') : [ˈkɐ.nu] or [ˈkɐ̃.nu] : first vowel is necessarily raised, and may be nasalized non-phonemically.
- tomo ('I take') : [ˈto.mu] or [ˈtõ.mu] : first vowel may be nasalized non-phonemically.
It follows from these observations that the vowels of BP can be described simply in the following way.
- BP has eight monophthongs—/a ɜ e ɛ i o ɔ u/—whose phonetic realizations may be affected by a nasal archiphoneme /N/. The vowel /ɜ/ is typically nasalized (in every position), but this is not phonemic.
- All eight vowels are differentiated in stressed and unstressed positions. But in word-final unstressed position and not followed by /N/, they reduce to three vowels—/a i u/—in most dialects. In this position, /a/ has a free variation [ɐ] and this fatally impairs /a-ɐ/ distinction. (For instance: the word ímã ('magnet') is effectively pronounced as either ima or ímam, depending on speaker.)
- Like the ん of Japanese, the archiphoneme /N/ is a nasal archiphoneme of syllabic codas and its actual place of articulation is determined by the following sound:
- otherwise it becomes a nasal approximant [ɰ̃] (as in Japanese kan'i 簡易 [かんい], etc.). After the vowels /e i/ this approximant may also be pronounced as [j̃]; and after /o u/ as [w̃] (free variations).
- The system of eight monophthongs reduces to five—/ɜ e i o u/—before /N/ and also in stressed syllables before heterosyllabic nasal consonants. The grapheme ⟨a⟩ stands for /ɜ/ in these cases.
- /eN/ is not allowed at word-final position because ⟨em⟩ stands for /ẽj/ in this case. (Here /j̃/ means the same phoneme that ⟨nh⟩ represents; and /e/ may be nasalized non-phonemically.) This is the only case of /j̃/ in coda-position.
With this description, the examples from before are simply /ʀoˈmɜN/, /ˈʒeN.ʀu/, /sej̃/, /kaNˈtaɾ/, /ˈkɜ.nu/, /ˈto.mu/. But there is no commonly accepted transcription for Brazilian Portuguese phonology. The reader is advised to look in the sources of examples if they wish to know precisely what is meant by phoneme symbols.
|Nasal diphthong||Usual spelling||Example||Meaning||Notes and variants|

|/ẽj̃/||em||bem||'well'||In Greater Lisbon, it merges to [ɐ̃j], which means mãe and bem rhyme.|
|/õw̃ ~ õ/ ||om||bom||'good'||The diphthongation of such nasal vowel is controversial.|
|/ũj̃/||ui||muito||'very', 'much'||Only nasalized in words derived from muito (including mui).|
Most times nasal diphthongs occur at the end of the word. They are:
- -ão or -am. [ɐ̃w̃]. Examples: pão ('bread'), cão ('dog'), estão ('they are'), vão ('they go'), limão ('lemon'), órgão ('organ'), Estêvão ('Steven'). When in the -am form (unstressed) they are always the 3rd person of the plural of a verb, like estavam ('they were'), contam ('they account'), escreveram ('they wrote'), partiram ('they left').
- -ãe [ɐ̃j̃]. It occurs in mãe(s) ('mother[s]') and in the plural of some words ending in -ão, e.g., cães ('dogs'), pães ('breads'); and exceptionally non-finally in cãibra ('cramp'). In Central European Portuguese, it occurs also in all words ending in -em, like tem ('he/she/it has'), bem ('well', 'good', as a noun), mentem (they lie), etc.
- -em [ẽj̃]. It occurs, both stressed and unstressed, in Brazilian Portuguese and in non-standard European Portuguese (northernmost and southern dialects) in word-final syllables ending in -em and -ém like bem, sem, além, as well as in verbs ending in -em (3rd person plural present indicative or verbs in -er and -ir). In Greater Lisbon, [ẽj̃] has merged with [ɐ̃j̃]; and it occurs duplicated in têm [ˈtẽj̃ẽj̃] or [ˈtɐ̃j̃ɐ̃j̃] (3rd person plural present indicative of ter, originally tẽem), which in Brazilian is homophonous with tem (the 3rd person singular).
- -õe [õj̃]. It occurs:
- in the present indicative of pôr and its derivatives; in the 2nd person singular (pões [põj̃s], opões, compões, pressupões), in the 3rd person singular (põe [põj], opõe etc.), and non-finally in the 3rd person plural (põem [ˈpõj̃ẽj̃], opõem etc.).
- in the plural of many words ending in-ão, e.g., limões ('lemons'), anões ('dwarfs'), espiões ('spies'), iões ('ions'), catiões ('cations'), aniões ('anions'), eletrões ('electrons'), neutrões ('neutrons'), protões ('protons'), fotões ('photons'), positrões ('positrons') and the plurals of all words with the suffix -ção (compare English -tion, like in communication), like comunicações ('communications'), provocações ('provocations').
- -om [õw̃]. It occurs in word-final syllables ending in -om like bom and som. However, it may be algo monophthongized [õ].
- -uim or -uin [w̃ĩ] Examples: pinguim ('penguin'), ruim ('bad'), ruindade ('badness'). Often realized [ũj̃].
- ui [ũj̃] occurs only in the words muito [ˈmũj̃tu] and the uncommon mui [mũj̃]. The nasalisation here may be interpreted as allophonic, bleeding over from the previous m (compare mãe with the same bleeding of nasality).
[j̃] and [w̃] are nasalized, non-syllabic counterparts of the vowels /i/ and /u/, respectively. At least in European Portuguese, the diphthongs [ɐ̃j̃, õj̃, ũj̃, ɐ̃w̃] tend to have more central second elements [ĩ̠̯, ũ̟̯] – note that the latter semivowel is also more weakly rounded than the vowel /u/.
- Between the base form of a noun or adjective and its inflected forms: ovo /o/ ('egg'), ovos /ɔ/ ('eggs'); novo /o/, nova /ɔ/, novos /ɔ/, novas /ɔ/ ('new' masculine singular, feminine singular, masculine plural, feminine plural);
- Between some nouns or adjectives and related verb forms: adj. seco /e/ ('dry'), v. seco /ɛ/ ('I dry'); n. gosto /o/ ('taste'), v. gosto /ɔ/ ('I like'); n. governo /e/ ('government') v. governo /ɛ/ ('I govern');
- Between different forms of some verbs: pôde /o/ ('he could'), pode /ɔ/ ('he can');
- Between some pairs of related words: avô /o/ ('grandfather'), avó /ɔ/ ('grandmother');
- In regular verbs, the stressed vowel is normally low /a, ɛ, ɔ/, but high /ɐ, e, o/ before the nasal consonants /m/, /n/, /ɲ/ (the high vowels are also nasalized, in BP);
- Some stem-changing verbs alternate stressed high vowels with stressed low vowels in the present tense, according to a regular pattern: cedo, cedes, cede, cedem /e-ɛ-ɛ-ɛ/; movo, moves, move, movem /o-ɔ-ɔ-ɔ/ (present indicative); ceda, cedas, ceda, cedam /e/; mova, movas, mova, movam /o/ (present subjunctive). (There is another class of stem-changing verbs which alternate /i, u/ with /ɛ, ɔ/ according to the same scheme);
- In central Portugal, the 1st. person plural of verbs of the 1st. conjugation (with infinitives in -ar) has the stressed vowel /ɐ/ in the present indicative, but /a/ in the preterite, cf. pensamos ('we think') with pensámos ('we thought'). In BP, the stressed vowel is /ɐ̃/ in both, so they are written without accent mark.
There are also pairs of unrelated words that differ in the height of these vowels, such as besta /e/ ('beast') and besta /ɛ/ ('crossbow'); mexo /e/ ('I move') and mecho /ɛ/ ('I highlight [hair]'); molho /o/ ('sauce') and molho /ɔ/ ('bunch'); corte /ɔ/ ('cut') and corte /o/ ('court'); meta /e/ ('I put' subjunctive) and meta /ɛ/ ('goal'); and (especially in Portugal) para /ɐ/ ('for') and para /a/ ('he stops'); forma /o/ ('mold') and forma /ɔ/ ('shape').
There are several minimal pairs in which a clitic containing the vowel /ɐ/ contrasts with a monosyllabic stressed word containing /a/: da vs. dá, mas vs. más, a vs. à /a/, etc. In BP, however, these words may be pronounced with /a/ in some environments.
Some isolated vowels (meaning those that are neither nasal nor part of a diphthong) tend to change quality in a fairly predictable way when they become unstressed. In the examples below, the stressed syllable of each word is in boldface. The term "final" should be interpreted here as at the end of a word or before word-final -s.
|Spelling||Stressed||Unstressed but not final||Unstressed and final|
|a||/a/ or /ɐ/||parto /a/
|/ɐ ~ a/ or /a/ (BP)||partir * /ɐ ~ a/ (BP), /ɐ/ (EP)
atuação /a/ (both BP and EP)
|/ɐ/ or /a/ (EP)|
|e||/e/ or /ɛ/||pega /ɛ/
|/e ~ ɛ/ or /ɪ ~ i/ (BP)||pregar * /e ~ ɛ ~ ɪ ~ i/ (BP), /ɨ/ (EP) (to nail)
pregar * /e ~ ɛ/ (BP), /ɛ/ (EP) (to preach, to advocate)
|/ɪ ~ i/ (BP)||move *|
|/ɨ ~ ∅/ or /ɛ/ (EP)||/ɨ ~ ∅/ (EP)|
|o||/o/ or /ɔ/||bola /ɔ/
|/o ~ ɔ/ or /ʊ ~ u/ (BP)||poder * /o ~ ɔ ~ ʊ ~ u/ (BP), /u/ (EP)
você * /o ~ ɔ/ (BP), /ɔ/ (EP)
|/ʊ ~ u/ (BP)||pato *|
|/u/ or /ɔ/ (EP)||/u/ (EP)|
* N.E.: The bold syllable is the stressed, but the pronunciation indicated on the left is for the unstressed syllable - not bold.
With a few exceptions mentioned in the previous sections, the vowels /a/ and /ɐ/ occur in complementary distribution when stressed, the latter before nasal consonants followed by a vowel, and the former elsewhere.
In Brazilian Portuguese, the general pattern in the southern and western accents is that the stressed vowels /a, ɐ/, /e, ɛ/, /o, ɔ/ neutralize to /a/, /e/, /o/, respectively, in unstressed syllables, as is common in Romance languages. In final unstressed syllables, however, they are raised to /ɐ/, /i/, /u/. In casual BP (as well in the fluminense dialect), /e, ɛ/, /o, ɔ/ may be raised to /ɪ ~ i/, /ʊ ~ u/ on any unstressed syllable, as long as it has no coda.
European Portuguese has taken this process one step further, raising /a, ɐ/, /e, ɛ/, /o, ɔ/ to /ɐ/, /ɨ/, /u/ in all unstressed syllables. The vowels /ɐ/ and /ɨ/ are also more centralized than their Brazilian counterparts. The three unstressed vowels /ɐ, ɨ, u/ are reduced and often voiceless or elided in fast speech. If /ɨ/ is elided, which mostly it is in the beginning of a word and word finally, the previous consonant becomes aspirated like in ponte (bridge) [ˈpõtʰ], or if it is /u/ is labializes the previous consonant like in grosso (thick) [ˈɡɾosʷ].
There are some exceptions to the rules above. For example, /i/ occurs instead of unstressed /e/ or /ɨ/, word-initially or before another vowel in hiatus (teatro, reúne, peão). /ɨ/ is often deleted entirely word-initially in the combination /ɨsC/ becoming [ʃC ~ ʒC]. Also, /a/, /ɛ/ or /ɔ/ appear in some unstressed syllables in EP, being marked in the lexicon, like espetáculo (spectacle) [ʃpɛˈtakulu]; these occur from deletion of the final consonant in a closed syllable and from crasis. And there is some dialectal variation in the unstressed sounds: the northern and eastern accents of BP have low vowels in unstressed syllables, /ɛ, ɔ/, instead of the high vowels /e, o/. However, the Brazilian media tends to prefer the southern pronunciation. In any event, the general paradigm is a useful guide for pronunciation and spelling.
Nasal vowels, vowels that belong to falling diphthongs, and the high vowels /i/ and /u/ are not affected by this process, nor is the vowel /o/ when written as the digraph ⟨ou⟩ (pronounced /ow/ in conservative EP). Nevertheless, casual BP may raise unstressed nasal vowels /ẽ/, /õ/ to [ɪ̃ ~ ĩ], [ʊ̃ ~ ũ], too.
In BP, an epenthetic vowel [i] is sometimes inserted between consonants, to break up consonant clusters that are not native to Portuguese, in learned words and in borrowings. This also happens at the ends of words after consonants that cannot occur word-finally (e.g., /d/, /k/, /f/). For example, psicologia ('psychology') may be pronounced [pisikoloˈʒiɐ]; adverso ('adverse') may be pronounced [adʒiˈvɛχsu]; McDonald's may be pronounced [mɛ̞kiˈdõnɐ̞wdʒis]. In northern Portugal, an epenthetic [ɨ] may be used instead, [pɨsikuluˈʒiɐ], [ɐðɨˈβɛɾsu], but in southern Portugal there is often no epenthesis, [psikuluˈʒiɐ], [ɐdˈvɛɾsu]. Epenthesis at the end of a word does not normally occur in Portugal.
The native Portuguese consonant clusters, where there is not epenthesis, are sequences of a non-sibilant oral consonant followed by the liquids /ɾ/ or /l/, and the complex consonants /ks, kw, ɡw/. Some examples:
- flagrante [flaˈɡɾɐ̃tʃi], complexo [kõˈplɛ.ksu], fixo [ˈfi.ksu] (but not ficção [fikˈsɐ̃w]), latex [latɛks], quatro [ˈkwatɾu], guaxinim [ɡwaʃiˈnĩ]
Further notes on the oral vowels
- Some words with /ɛ ɔ/ in EP have /e o/ in BP. This happens when those vowels are stressed before the nasal consonants /m/, /n/, followed by another vowel, in which case both types of vowel may occur in European Portuguese, but Brazilian Portuguese only allows high vowels. This can affect spelling: cf. EP tónico, BP tônico "tonic".
- In most BP, stressed vowels have nasal allophones, [ɐ̃], [ẽ], [ĩ], [õ], [ũ], etc. (see below) before one of the nasal consonants /m/, /n/, /ɲ/, followed by another vowel. In São Paulo, Southern Brazil, and EP, nasalization is nearly absent in this environment, other than in compounds such as connosco, comummente (spelled conosco, comumente in BP).
- Most BP speakers also diphthongize stressed vowels to [aʲ], [ɛʲ], [eʲ], [oʲ], [ɔʲ], [uʲ], etc. (except /i/), before a sibilant at the end of a stressed syllable (written s, x, or z). For instance, Jesus [ʒeˈzuʲs] ('Jesus'), faz [faʲs] ('he does'), dez [dɛʲs] ('ten'). One often common exception to this realization is in the accent of gaúchos. This has led to the use of meia (from meia dúzia 'half a dozen") instead of seis [sejs] ('six') when making enumerations, to avoid any confusion with três [tɾeʲs] ('three') on the telephone.
- In Greater Lisbon, /e/ is pronounced [ɐ(ʲ)] when it comes before a palatal consonant /j/, /ʎ/, /ɲ/ or a palato-alveolar /ʃ/, /ʒ/, followed by another vowel; as well as [ẽj̃] is pronounced [ɐ̃j̃].

When two words belonging to the same phrase are pronounced together, or two morphemes are joined in a word, the last sound in the first may be affected by the first sound of the next (sandhi), either coalescing with it, or becoming shorter (a semivowel), or being deleted. This affects especially the sibilant consonants /s/, /z/, /ʃ/, /ʒ/, and the unstressed final vowels /ɐ/, /i, ɨ/, /u/.
As was mentioned above, the dialects of Portuguese can be divided into two groups, according to whether syllable-final sibilants are pronounced as postalveolar consonants /ʃ/, /ʒ/ or as alveolar /s/, /z/. At the end of words, the default pronunciation for a sibilant is voiceless, /ʃ, s/, but in connected speech the sibilant is treated as though it were within a word (assimilation):
- If the next word begins with a voiceless consonant, the final sibilant remains voiceless /s, ʃ/; bons tempos [bõʃ‿ˈtẽpuʃ] or [bõs‿ˈtẽpus] ('good times').
- If the next word begins with a voiced consonant, the final sibilant becomes voiced as well /z, ʒ/; bons dias [bõʒ‿ˈdiɐʃ] or [bõz‿ˈdʒiɐs] ('good days').
- If the next word begins with a vowel, the final sibilant is treated as intervocalic, and pronounced [z]; bons amigos [bõz‿ɐˈmiɡuʃ] or [bõz‿aˈmiɡus] ('good friends').
When two identical sibilants appear in sequence within a word, they reduce to a single consonant. For example, nascer, desço, excesso, exsudar are pronounced with [s] by speakers who use alveolar sibilants at the end of syllables, and disjuntor is pronounced with [ʒ] by speakers who use postalveolars. But if the two sibilants are different they may be pronounced separately, depending on the dialect. Thus, the former speakers will pronounce the last example with [zʒ], whereas the latter speakers will pronounce the first examples with [s] if they are from Brazil or [ʃs] if from Portugal (although in relaxed pronunciation the first sibilant in each pair may be dropped). This applies also to words that are pronounced together in connected speech:
- sibilant + /s/, e.g., as sopas: either [ʃ‿s] or [s] or [ʃ];
- sibilant + /z/, e.g., as zonas: either [ʒ‿z] or [z] or [ʒ];
- sibilant + /ʃ/, e.g., as chaves: either [ʃ] or [s‿ʃ];
- sibilant + /ʒ/, e.g., os genes: either [ʒ] or [z‿ʒ].
Normally, only the three vowels /ɐ/, /i/ (in BP) or /ɨ/ (in EP), and /u/ occur in unstressed final position. If the next word begins with a similar vowel, they merge with it in connected speech, producing a single vowel, possibly long (crasis). Here, "similar" means that nasalization can be disregarded, and that the two central vowels /a, ɐ/ can be identified with each other. Thus,
- /a, ɐ/ + /a, ɐ/ → [a(ː)]; toda a noite [ˈtoda(ː) ˈnoi̯tʃi] or [ˈtoda(ː) ˈnoi̯tɨ] ('all night'), nessa altura [ˈnɛs‿awˈtuɾɐ] or [ˈnɛs‿aɫˈtuɾɐ] ('at that point').
- /a, ɐ/ + /ɐ̃/ → [ã(ː)] (note that this low nasal vowel appears only in this situation); a antiga ('the ancient one') and à antiga ('in the ancient way'), both pronounced [ã(ː)‿ˈtʃiɡɐ] or [ã(ː)‿ˈtiɡɐ].
- /i/ + /i, ĩ/ → [i(ː), ĩ(ː)]; de idade [dʒi(ː)‿ˈdadʒi] or [di(ː)‿ˈdadɨ] ('aged').
- /ɨ/ + /ɨ/ → [ɨ]; fila de espera [ˈfilɐ d‿ɨʃˈpɛɾɐ] ('waiting line') (EP only).
- /u/ + /u, ũ/ → [u(ː), ũ(ː)]; todo o dia [ˈtodu(ː) ˈdʒiɐ] or [ˈtodu(ː) ˈdiɐ] ('all day').
- /i/ + V → [jV]; durante o curso [duˈɾɐ̃tʃj‿u ˈkuɾsu] ('during the course'), mais que um [majs kj‿ũ] ('more than one').
- /u/ + V → [wV]; todo este tempo [ˈtodw‿ˈestʃi ˈtẽpu] ('all this time') do objeto [dw‿obiˈʒɛtu] ('of the object').
In careful speech and in with certain function words, or in some phrase stress conditions (see Mateus and d'Andrade, for details), European Portuguese has a similar process:
- /ɨ/ + V → [jV]; se a vires [sj‿ɐ ˈviɾɨʃ] ('if you see her'), mais que um [majʃ kj‿ũ] ('more than one').
- /u/ + V → [wV]; todo este tempo [ˈtodw‿ˈeʃtɨ ˈtẽpu] ('all this time'), do objeto [dw‿ɔbˈʒɛtu] ('of the object').
- /ɨ/ + V → [V]; durante o curso [duˈɾɐ̃t‿u ˈkuɾsu] ('during the course'), este inquilino [ˈeʃt‿ĩkɨˈlinu] ('this tenant').
- /u/ + V → [V]; todo este tempo [tod‿ˈeʃtɨ ˈtẽpu] ('all this time'), disto há muito [diʃt‿a ˈmũi̯tu] ('there's a lot of this').
Unlike French, for example, Portuguese does not indicate most of these sound changes explicitly in its orthography.
Primary stress may fall on any of the three final syllables of a word, but mostly on the last two. There is a partial correlation between the position of the stress and the final vowel; for example, the final syllable is usually stressed when it contains a nasal phoneme, a diphthong, or a close vowel. The orthography of Portuguese takes advantage of this correlation to minimize the number of diacritics.
Because of the phonetic changes that often affect unstressed vowels, pure lexical stress is less common in Portuguese than in related languages, but there is still a significant number of examples of it:
- dúvida /ˈduvidɐ/ 'doubt' vs. duvida /duˈvidɐ/ 's/he doubts'
- ruíram /ʁuˈiɾɐ̃ũ/ 'they collapsed' vs. ruirão /ʁuiˈɾɐ̃ũ/ 'they will collapse'
- falaram /faˈlaɾɐ̃ũ/ 'they spoke' vs. falarão /falaˈɾɐ̃ũ/ 'they will speak' (Brazilian pronunciation)
- ouve /ˈovi/ 'he hears' vs. ouvi /oˈvi/ 'I heard' (Brazilian pronunciation)
- túnel /ˈtunɛl/ 'tunnel' vs. tonel /tuˈnɛl/ 'wine cask' (European pronunciation)
Tone is not lexically significant in Portuguese, but phrase- and sentence-level tones are important. As in most Romance languages, interrogation on yes-no questions is expressed mainly by sharply raising the tone at the end of the sentence. Exception is the word 'oi' that is subject to meaning changes: in exclamation tone 'oi' means 'hi/hello', in interrogative tone 'oi' means 'I didn't understand'.
