You won't hear Katrina Kaif speaking in RGV's Sarkar. There were rumours that Katrina Kaif will get her voice dubbed in her movies. But since her character in Maine Pyar Kyon Kiya is that of an NRI girl, she did the dubbing herself. Most of her dialogues were in English and she spoke very little Hindi.
But in Sarkar, where she plays an Indian, she has got her dialogues dubbed. Katrina has been taking Hindi-speaking classes for more than a year and states that she is capable of dubbing herself in her films.
