The phonology of Catalan, a Romance language, has a certain degree of dialectal variation. Although there are two standard varieties, one based on Central Eastern dialect and another one based on South-Western or Valencian dialect, this article deals with features of all or most dialects, as well as regional pronunciation differences.
Catalan is characterized by final-obstruent devoicing, lenition, and voicing assimilation; a set of 7 to 8 phonemic vowels, vowel assimilations (including vowel harmony), many phonetic diphthongs, and vowel reduction, whose precise details differ between dialects.
