Vidya's Voice Different

Hey guys i have just watched today's episode in USA where Vidya speaks English for the first time at Sagar's birthday party. So i noticed that when Vidya was speaking English her voice was really different. She sounded as if her voice is really light and thin. But when she spoke in Hindi, she sounded depressed and you could really tell that she is crying without even looking at the video. Si was just wanted to share this with you all. What do you guys think?
