I need a native here (or two). Everybody says (everybody means Brazilians and Spanish) that /r/ sound in inland São Paulo state when followed by a consonant (like "porta") sounds exactly like English /r/. Could you English-speaking people check this for me, pelase?
I've just a video here (with accent really exaggerated), check 0:07 to hear it. https://www.youtube.com/watch?v=UkP8S2Kxg-8
