What language were the people speaking when chanting in The Dark Knight Rises?

They chanted like,

Dey-shey dey-shey Bah-sur-rah bah-sur-rah.

If we translate the chant to Hindi, which closely means,

"long live, long live".

I think, Nolan would've chosen that phrase because the pitfall/prison portrayed in the movie is Mehrangarh Fort, located in India. So, I guess Nolan would be using the Hindi chant.
