You're the most welcome Karim :) 

Thanks a lot Meriem.

I used to have this problem too because I was afraid of speaking.

I can suggest you some links that may help you to improve your speaking and your accent (American accent) with audio books.

 Here are the links:

American Accent Training:

Learn Real English:

I hope you're gonna find them useful as I did :) 

For me now, i am listening to English songs,watching English movies with subtitles in English and little practice.
My problem is: I am finding hard to speak in English yet, and i hope to improve my English soon .
