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, Wheeler (1979) and Mascaró (1976) analyze Central Eastern varieties—the former focusing on the educated speech of Barcelona and the latter focusing more on the vernacular of Barcelona— and Recasens (1986) does a careful phonetic study of Central Eastern Catalan.[1][2]
Catalan shares features with neighboring Romance languages (Italian, Sardinian, Occitan, Spanish).[3]
Phonetic notes: /t/ and /d/ are denti-alveolar, having both dental and alveolar contact with the tongue. /n/, /l/, and /ɾ/ are "front alveolar;" /s/ and /r/ are "back alveolar" (or postalveolar); /ʎ/ and /ɲ/ are "front alveolo-palatal"; and /ɕ/, /ʑ/, /tɕ/ and /dʑ/ are "back alveolo-palatal."[5]
Plosives: Voiced plosives become lenited (that is, fricatives or approximants of the same place of articulation) "only in syllable onsets, after continuants."[6] Exceptions include /d/ after lateral consonants and /b/ after /f/: ull de bou [uʎ də ˈβɔw] ('round window'); bolígraf boníssim [buˈliɣɾəv buˈnisim] ('excellent ballpoint'). In the coda position, these sounds are always realized as plosives[7] except in Valencian, where they are lenited.[8]
/b/ and /g/ may be geminated in certain environments (poble [ˈpɔbblə] 'village').[9]
In Majorcan varieties, /k/ and /g/ become [c] and [ɟ] word-finally and before front vowels;[10] in some of these dialects, this has extended to all environments except before liquids and back vowels [ˈbanʲc] ('bench').[11]
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')[12] 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.[21] Also, intervocalic affricates are predominately long, especially those that are voiced or occurring immediately after a stressed syllable (fletxa [ˈflet.tɕə] 'arrow').[22]
Fricatives: /v/ only occurs in Balearic[23] and southern Valencian as well as northern Valencian and southern Catalonia. Everywhere else, it has merged with /b/.[24] 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.[25]
In Valencian, /s/ and /ɕ/ are auditorily similar such that neutralization may occur in the future.[26] 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').[27]
Sonorants: While "dark" (velarized) [ɫ] may be a positional allophone of /l/ in most dialects (such as in the syllable coda[28]), /l/ is dark irrespective of position in Eastern dialects like Majorcan.[29]
