Definitely !!!! But also try to improve your pronunciation skills with something you enjoy like singing, watching a tv serie, reading aloud, listening to the radio ( where they use english of course) Or, start thinking in english the whole day, it works for meeeeee ! (ok, I also lived in USA for more than 2 years, so I'm a cheater =p but but but do your best and you'll see !!! ) ^^

Hi , this site will give you lots of advice and websites for improving spoken English http://www.italki.com/knowledge/contribution-Spoken+English.htm

Hi... It is a question of desire too...

yeah somehow. it improves the power of memorizing the words.

I think so. It helps me visualize the phonetics of the word and understand the pronunciation better.
