Yes. Well some people have strong accents and some people don't. This pertains to every language in the world. Even in North, worlds like Eschool, Escale etc are quite heard. In Telugu, people say saar instead of sir. In Tamil, it is Aartel instead of Airtel. I shouldn't really suggest to dial down the accent but once in a while it would really help. And on the other hand, we have people like Shashi Tharoor. That much is also not expected, just to be clear.
