Hey, I'll try to help people who speak english to learn brazilian portuguese. Actually, the biggest difference between brazilian portuguese and the portuguese from portugal is the pronunciation. So, i'm going to put the sound here like in these wikis http://www.italki.com/knowledge/wikilist-Portuguese-English-1-sl.htm .
First of all, the alphabet, I recorded my voice spelling the alphabet:

C - Boomp3.com

D - Boomp3.com

E - Boomp3.com

F - Boomp3.com
