Radha and Shlok's voice?

Has anyone noticed that Radha and Shlok's voice and tone has changed from the time they go to get Radha's eyes treated to now.

What do you guys think?

Diya,Maybe they r using dubbed voice by someone else...
When they went for shopping,after she got out from the hospital...they used false voices for both..at the counter when they were paying for the clothes etc...

Other than that,i havent noticed...Deepthi's voice cracks in between,maybe she is just too tired and overworked.Seems she works 13 hrs a day??As per the article...

Deepti has been sounding very bunged up lately. It is her voice but I think she has a cold!!!

I guess Mini is right the voice was dubbed when they went shopping and like Simran says Radha has a cracked voice now.

Hope they do not replace her. I like Deepti Devi in the role she is playing as Radha.
