Constant practice of tongue placement with a speech coach.

It's called "placing your voice". That's where the 'natural' sound of an accent is focussed and resonated. Aside from pronunciation differences, the various English accents will place the sound in different parts of the mouth, throat, perhaps nose (nasal accent!) or even down in the chest.

thanks Sayeed so much,,,,, best of luck for you too. by the way there is a training that helps you to control your accent..i'm still searching. see you soon

its little tough to adopt a new language... dont worry, just go ahed. practice more and more. u can watch the funny movie or some vedio wht u like most. it will dafinately help u. and never lose ur patient. everything is looks difficult at the begining but u will find the control just after a while... jst keep going on. best wishes for u. may allah help u to adapt it as early as possible. ameen.

yeah but really it isn't easy to bring the sound from the right location..maybe controlling the tongue is much easier
