Hello Nita,
I assume you are Bengali or from close by Bengal. That reminds me of two incidents to support your view.
We had a draughtsman from Bengal who came late one day. I asked him, "Mr. D, why are you late today?" His response was, "My 'boss' came late." So, I asked him why he should be late if his boss came late. Then someone said, "He meant that his bus came late."
The second instance was in an interview. An officer from Bengal asked an interviewee, "Could you please define a 'Bolt'?" The interviewee said that bolts come in many forms: hexagonal head, Philips head, slotted head, and also with different types of threads... Then another member of the panel intervened and told the interviewee that the other member wanted him to define a Volt as in voltage.
I have had students from China who could not pronounce the letter 'R'. They always used the sound of 'L': Red lorry became 'Led lorry'.
Similarly, some from the South pronounce words like College, Only, etc., differently to the standard BBC broadcast.
Hence, you are perfectly right; we need to neutralize the influence of our MT.
Have a nice weekend.

PS: Reading aloud to oneself or speaking in front of a mirror or reading a lot will not help neutralize the MTI. It's listening to news where presenters use neutralized language, record it, and practice to pronounce the same way that will help.
I agree 110% with Simhan. Besides, when someone seeks help, we need to lend a hand. How would you feel when someone speaks your mother tongue wrongly (pronounced)? Moreover, it's essential to get over MTI to make one's communication effective.
If I say "I am going to eat my lunch" or "She's going to Bangalore by bus" what would be your reaction?
