Problems on Portuguese pronunciation I just started to learn portugues, the biggest problem for me now is pronunciation,especially for some certain alphabets,like the letter 'D','T','R'... It sounds like 'd' in english when we read 'D' in a single letter,while in words, may more sounds like the english letter'j'(jeep).It is said that there's little difference between the alphabet 'T' and the alphabet 'D' in portugues,but according to portugues courses listed on some websites,surely that's not the case.There's the difference.So when shall i have to make the sound 't' like 'd'?The last one,the letter R, pretty difficult for me, i can hardly read it naturally. Thank you all.
