Radhika Poovayya, founder and director of Samvaad Institute of Speech and Hearing, said there should be a strict law that prevents any character with stammering to be used to draw laughter.
"Our demand to the I&B ministry is to stop films from showing stammering inappropriately. Show them (people who stammer) as normal people and don't portray them for just a few laughs," Ms Poovayya said.
"They know what to say, but they take a little more time to say. So we have to give them the time without rolling our eyes, giving a word in between, helping them. They don't need any help. If you try to help them, they get even more insulated," she said.
Abhiya, a student at the Samvaad Institute of Speech and Hearing, said, "We are spreading awareness so that we can develop a community to support them."
