Hi Buntheng!! Welcome to the warmest forum in the world,
I think!
Your question is such a very, very easy one
, yet it is absolutely hard to find the answer! To my point of view, trying to change the pronunciational style is such a difficult thing to do. But it doesn't mean it is impossible!! For instance, my friend, Try, he is such a hard-learning-and-trying person and he can change the way he speaks English successfully! As I observed what I found from him are:
-Try to listen to the native-English speakers directly ( live speaking, via bbc, abc, voa or other English tool sources)
-Learn to speak as much as possible, as much as possible, as much as possible by trying to bend your tongue as if the native voice.
-Remind or forethink when you will say something out in order to voice out as what style you expect or prefer.
I.....think......that is all.
Note*: Indoingso, it is required you to spend long term practicing if you want to meet your end. Try and practice are the best motivating materials to success.
Wish your dream go like a dream!!
Have fun!!!
Kimlong
