Dear Aspirant,

There no such specialized courses for RJ. But you can study mass communication from renowned colleges like Indian Institute of Mass Communication, Asian Academy of Film and Television, Academy 18 Networks Ltd etc wherein you will get exposure.

All India Radio (AIR) also conducts audition every three months so you can try for that. If got selected training will be provided to you by AIR. Also there are professional voice over crash courses, workshops.

Hope this helps
