The phonology of Catalan, a Romance language, has a certain degree of dialectal variation. Although there are two main dialects, one based on Eastern Catalan and one based on Valencian, this article deals with features of all or most dialects as well as regional pronunciation differences. Various studies have focused on different Catalan varieties; for example, and analyze Central Eastern varieties—the former focusing on the educated speech of Barcelona and the latter focusing more on the vernacular of Barcelona— and does a careful phonetic study of Central Eastern Catalan.
Catalan shares features with neighboring Romance languages (Italian, Sardinian, Occitan, Spanish).

Plosives: Voiced plosives become lenited (that is, fricatives or approximants of the same place of articulation) "only in syllable onsets, after continuants. Exceptions include /d/ after lateral consonants and /b/ after /f/: ull de bou ('round window'); bolígraf boníssim ('excellent ballpoint'). In the coda position, these sounds are always realized as plosives except in Valencian, where they are lenited.
/b/ and /g/ may be geminated in certain environments (poble [ˈpɔbblə] 'village').
In Majorcan varieties, /k/ and /g/ become [c] and [ɟ] word-finally and before front vowels; in some of these dialects, this has extended to all environments except before liquids and back vowels [ˈbanʲc] ('bench').
Affricates: The phonemic status of affricates is dubious; after other consonants, affricates are in free variation with fricatives, e.g. clenxa [ˈklɛnʲtɕə] ~ [ˈklɛnʲɕə] ('hair parting') and may be analyzed as either single phonemes or clusters of a stop and a fricative.
There is dialectal variation in regards to affricate length, with long affricates occurring in both Eastern and Western dialects such as in Majorca and specific Northern and Southern Valencian areas and short affricates being otherwise widespread throughout Valencia. Also, intervocalic affricates are predominately long, especially those that are voiced or occurring immediately after a stressed syllable (fletxa [ˈflet.tɕə] 'arrow').
Fricatives: /v/ only occurs in Balearic and southern Valencian as well as northern Valencian and southern Catalonia. Everywhere else, it has merged with /b/. In Majorcan, [v] and [w] are in complementary distribution, with [v] occurring before vowels (e.g. blava [ˈblavə] 'blue' fem. vs blau [blaw] 'blue' masc.). In other varieties that have both sounds, they are in contrast before vowels, with neutralization in favor of [w] before consonants.
In Valencian, /s/ and /ɕ/ are auditorily similar such that neutralization may occur in the future. In Northern Valencian, /ɕ/ is depalatalized to [jsʲ] or [js] as in caixa [ˈkajsə] ('box'), Central Valencian words like mig ('half') and leig have been transcribed with [ts] rather than [tɕ], and Southern Valencian /tɕ/ "has been reported to undergo depalatalization without merging with [ts]" as in baixar ('to go down').
Sonorants: While "dark" (velarized) [ɫ] may be a positional allophone of /l/ in most dialects (such as in the syllable coda), /l/ is dark irrespective of position in Eastern dialects like Majorcan.
In careful speech, /n/, /m/, and /l/ may be geminated (e.g. innecessari [innəsəˈsaɾi] 'unnecessary'; immens [imˈmɛns] 'huge'; il·lusió [iɫɫuˈzio] 'illusion'). A geminated /ʎʎ/ may also occur (e.g. espatlla [əsˈpaʎʎə] 'shoulder').
Catalan possesses seven vowel phonemes (see chart at right). In unstressed syllables, /e/, /ɛ/, and /a/ are reduced to [ə] while /o/ and /ɔ/ are reduced to [u]. In Western Catalan dialects, [e], [o], and [a] may appear in unstressed syllables as well.
In Majorcan, [ə] appears in stressed position.
There are also a number of phonetic diphthongs, all of which begin (rising diphthongs) or end (falling diphthongs) in [j] or [w]:
| [ej] | rei | 'king' | [ɛw] | peu | 'foot' |
| [uj] | avui | 'today' | [ow] | pou | 'well' |
| [ja] | iaia | 'grandma' | [wa] | quatre | 'four' |
| [jɛ] | veiem | 'we see' | [wə] | aigua | 'water' |
Catalan also possesses two sets of diphthongs in variation; [wi] varies with [uj] (as in afluixar [aflujˈɕa~aflwiˈɕa] 'to loosen') and [iw] with [ju].
The dialectal distribution of compensatory diphthongization is almost entirely dependent on the dorsal plosive (/k~c/) and the extent of consonant assimilation (whether or not it's extended to palatals).
Voiced affricates are devoiced after stressed vowels in dialects like Eastern Catalan where there may be a correlation between devoicing and lengthening (Gemination) of voiced affricates: metge ('doctor') /ˈmeddʑə/ → [ˈmettɕə]. In Barcelona, voiced plosives may be geminated and devoiced (poble [ˈpɔppɫə] 'village').
Word-medial codas are restricted to one consonant + [s] (extra [ˈɛks.tɾə]). In the coda position, voice contrasts among obstruents are neutralized. Although there are exceptions (such as futur [fuˈtuɾ] 'future'), syllable-final /ɾ/ is often lost before a word boundary or before the plural morpheme of most words: color [kuˈɫo] ('color') vs. coloraina [kuluˈɾajnə].
In Catalan, obstruents fail to surface word-finally when preceded by a homorganic consonant (e.g. ). Complex codas simplify only if the loss of the segment doesn’t result in the loss of place specification.
| Final | Internal | Gloss | |
|---|---|---|---|
| no cluster | [ˈkam] | [kəmˈpɛt] | 'field' |
| [ˈpun] | [punˈtɛt] | 'point' | |
| [ˈbaŋ] | [bəŋˈkɛt] | 'bank' | |
| [məˈlal] | [mələlˈtɛt] | 'ill, sick' | |
| [ˈɔr] | [urˈtɛt] | 'orchard' | |
| [ˈgus] | [gusˈtɛt] | 'taste' | |
| cluster | [ˈserp] | [sərˈpɛt] | 'snake' |
| [ˈdisk] | [disˈkɛt] | 'disk' | |
| [ˈmɔɫk] | n/a | 'I grind' |
Word-final fricatives (except /f/) are voiced before a following vowel, e.g. bus enorme ('huge diver'). In Majorcan and Minorcan Catalan, /f/ undergoes total assimilation to a following consonant (just as stops do): buf gros ('large puff').
The differences in the vocalic systems outlined above are the main criteria used to differentiate between the major dialects: distinguishes two major dialect groups, Western dialects and Eastern ones; the latter of which only allow [i], [ə], and [u] to appear in unstressed syllables and include North Catalan, Central Catalan, Balearic, and Alguerese. Western dialects, which allow any vowel in unstressed syllables, include northern and western Catalan, and Valencian.
