[QUOTE=sundar_mpm;2072236]MTI - Mother Tongue Influence.
..., but you may choose the neutral accent, i.e., our Indian accent which eliminates MTI.
Good answers to your question of reducing MTI. However, I definitely don't think the 'Indian accent' is Neutral! All of us, irrespective of our country or state of origin have some sort of an accent. One can at best pronounce many words the way native speakers of English do. Again this depends on whether one is aping the Brits or Americans. This is mainly done we hope to facilitate communication, especially if one's working in a BPO Industry
However, it's not only completely taxing but also ridiculous to make it our life's mission to perfectly imitate their accent. At best people sound like good mimics, at worst completely fake and obnoxious.
I personally love a natural Indian accent. This doesn't have the guttural articulation like some native speakers do. So be proud of your natural accent not try and kill it completely.
