The forthcoming Diccionari de la pronúncia catalana (DPC) aims to represent the recommended pronunciations and the pronunciations in common use of the four varieties of Catalan as spoken in Spain, that is, North Western, Valencian, Central, and Balearic. Compiled in collaboration with phoneticians from the Valencian area and the Balearic Islands, it contains about 170,000 entries and over 750,000 pronunciations, more than 10,000 of which have been verified through usage polls. The culmination of over fifteen years’ work, the dictionary is modelled mainly on J.C. Wells’ Longman Pronunciation Dictionary (1990; 2000, 2nd ed.) for English. The DPC includes a full general vocabulary as well as literary, scientific and technological terms (covering computing, law, medicine, and communications), and specific vocabulary of the four Catalan varieties. It also contains Catalan and foreign proper names (people, places, commercial, artistic, etc.), loanwords and neologisms, as well as abbreviations, acronyms, and onomatopoeias. In addition the DPC includes biographical and terminological information relating to the phonetic sciences.
