the best is to listen to native speakers and try to emulate them. You need a good ear to be able to tell the difference between sounds. Also record your voice and play it back to compare.

I think you should speak with informal or professional tutor to practice that. Additional practice for you can be to record yourself when you read an electronic book in PDF. Then you can find the same book but on Youtube and listen to the same story that is read by somebody. You can also try to sing your favorite song in English and then to compare it with the origin version.

I really like that idea about read a book and find someone else he read it . I Will make research if I don't find any thing I will write you back to advise me some book with the records

can you write a site for English native conversation or other way I can listen and deal with them .... Thanks
