dialoguebaazi

I'm reading an article published in the Indian Express that deals with foreign students going to Mumbai's acting schools to become film producers. They use the term "dialoguebaazi" but the meaning of that word does not appear clearly to me.

It is not a proper word in the sense that it has come up with creativity in spoken language. You can add "baazi" at the end of a lot of things, to mean to say "of or related to XYZ"

E.g. Patangbaazi => art of flying kites (in the sky)
