Is there a particular technological product you want to listen with? Like, just an ipod? On the computer?

I've had many foreign friends who were learning English when I first met them. They told me that listening to popular songs on the radio or on records helped them since they could hear the words over and over again. They also watched dramas and sitcoms on TV, both of which helped them in understanding context, slang, etc. If you have access to such materials, all I can say is to give it an honest try! Such listening, however, will only improve your understanding of spoken English. If you want to speak English well, you actually have to talk with other people! Good luck!

I listen "BBC english learning" there well and clearly explain as usual Englishmen and as discuss some themes, the main thing talk that to you it was clear about what speak, as it is possible to listen to radio in English, but I do not advise to listen to audio-books.
