facing problem in english accent
Do you mean that you have trouble understanding the accent of actors from England or the UK?
The best way to overcome this is to practice more listening. If you are watching movies, you can turn on the subtitles when you first start to watch them, and then rely on them less and less as you become more familiar with the accent. It usually just takes a bit of time and adjustment to get it right and understand accents that you aren’t used to.
