To do that, you have understand the regional pride of these people and also that there were several kingdoms in the north that had already treated them as a single administrative unit. I dont know about the east, but in the south there were many centuries worth of kings that ruled these states separately before the brits came. And this idea of india formed around the late 19th century. Yes there might have been a bharat during the ramayana, but that was thousands of years ago. So understand the reality. With the technology thats available multilanguage interfaces exist and transciribing can be done smoothly. if you have a lot of people to people to contact pan india then learn a language. dont expect people who dont have such a need to learn.
