The Fluminense dialect (to hear ) is a dialect of Brazilian Portuguese spoken in the Brazilian states of Rio de Janeiro and Espírito Santo and in the regions bordering the neighboring states.
Its origin is found in some regions of Portuguese colonization, possibly more accentuated after the arrival of the court in Brazil in 1808 . The dialect has features in common with European Portuguese, in particular an eventual tendency to reduce the vowels / e / e / o / to / i / e / u / when unstressed, an accent speech rate (unstressed syllables of shorter duration than the tonic) [ 1 ] and palatalization of the s and z at the end of the syllable ( same / meʒmuʃ /). In contrast to the European Portuguese, this phenomenon does not occur before another consonant alveolar fricative (as in the s s enhores). In the capixaba area of the dialect, sibilants are preferred (as in the state of Minas Gerais, in the south of the state of Bahia and in the microregion of the Paraíba Fluminense Valley, in the south of the state of Rio de Janeiro).
In 1961 , by decree of the then president of the republic Jânio Quadros , known for his extravagant acts, he was recognized as the only official dialect of Brazil [ citation needed ] .
It presents a phonological structure hardly found in other regions, with some of the characteristics peculiar to the Fluminense dialect the r aspirated at the end of the syllable and the abundance of diphthongs and fricative palatal phonemes, to the detriment of the mammographic images.
