Hello everyone :) How do I know when to use u ũ o õ i ĩ e ẽ and etc??
I've found this website for you: http://www.learn-portuguese-with-rafa.com/portuguese-pronunciation.html
You'll see two texts to read along with the woman. Clearly it's done by a woman from Portugal, so it's quite different from what you'll hear if ever in Brazil... Also,the rules are based on EU-PT,but many of them can be used with BR-PT
1- He explained that "têm" is pronounced like we'd have two "e" (teem). But that doesn't happen with BR-PT.
2- They pronounce "s" at the end of a word like sh. Brazilians usually don't (except for some regions in Brazil,like Riode Janeiro)
3-~ is not an accent,but shows the letter has nasal sound

Hi =) You don't use "ũ, ĩ, ẽ" in Portuguese. Does exist "ão", e.g.: "Coração" (Heart), "Movimentação" (Movement), as exist "ê", eg.: "Você" (you), "Ocorrência" (ocurrence), "Três" (three), and "õ", e.g.: "Impõe" (imposes), Questões (Questions).
Bons estudos!!!!! (God job!)
