The best way to improve your speaking would be to talk with natives English speakers on Skype. There are a lot of English speakers on Italki, such as me, and most of them will have Skype. Som try asking people if they will help you.

Hi, Do you know shadowing method? Go to youtube! You're welcome!

Omega gave a really good answer, but if you are still a bit reluctant of using your english skills in fear that the other person might not understand you, then i can advise you something that worked for me just fine, specially when i was in the UK and people spoke so differently and so fast! Watching shows and tv series that resemble the everyday life of the culture you are interested in (and in the language you are learning, of course) gives you some confidence and some tips to start speaking more open and fluently. Hopefully this is helpful for you too!
