Big B to copyright his voice?

Recently, we have been hearing many landmark voices after being imitated. But has it gone to such a high extent that one of our best known actors, with one of the most known voices, is going to take the major step of copyrighting it?  

 

Well, Big B is all ready to take this decision. His voice is definitely one of the most imitated voices, but after his voice was misused in a smoking commercial that promoted the topic, he was in shock since he would never condone such activities! He decided something needed to be done!

 

Now, with the decision of getting his voice copyrighted, Big B won't let any commercials use his voice without his permission.
