Classical pronunciation norm, established at the end of the 19th century, bore two names - Croatian and Serbian. Such name was not appropriate for shared Croatian language because it does not unite connect majority of Croats and does not clearly determine Croatian national identity. Those roles, as shown by a sociophonetic research, are accomplished by the accepted pronunciation norm based on Cakavian, Kajkavian and Stokavian dialects and mostly synthetized in Zagreb. The main characteristics of the accepted pronunciation norm are: three accent types, shortening of the post-accentual length, short pronunciation of vocalic vertical bar r vertical bar the possibility of falling accents appearing on all syllables, two-phonemic vertical bar je vertical bar developed from the both old long jat and old short jat and the neutralisation of differentiation of postalveolar / and palatal affricates.
