In Ghulam?

why did they change rani mukherjee's voice?
i suppose her voice is better for that part than whoever's voice that in fact was

Answers: They other change their voice - The actors and actress don't sing either for themselves usually. Shahrukh Khans voice is other changing! But it be probably because they needed a different voice for her part -even if hers be better. I guess it's up to the director.
