Fluminense, also known as Flu-Capixaba, is a dialect of Portuguese spoken in most of the Brazilian states of Rio de Janeiro and Espírito Santo, as well as parts of southeastern Minas Gerais.A modernidade da língua: o dialeto do Sudeste. Revista Linguagem Contemporânea. 15 de junho de 2008.Falas fluminense/capixaba e o carioca: quais são as diferenças entre elas? O Ham-Let. 26 de maio de 2007. It is considered to be one of the closest Brazilian Portuguese dialects to the variations of the language spoken in Portugal.
The dialect is notorious for the presence of vowel reduction of /e/ and /o/ into /i/ and /u/, stress timing, the palatalization of /s/ and /z/ in the end of syllables into /ʒ/ or /ʃ/ and the abundance of diphtongs and palatal fricative phonemes, which differentiates it from the Carioca dialect, the closest variation of Portuguese to Fluminense.^ a b Parkinson, Stephen. "Phonology". In The Romance Languages edited by Martin Harris and Nigel Vincent. Routledge, 1988. Pp. 131–169. Fluminense speakers tend to substitute the /ɾ/ sound in the end of words for /ʁ/.
