simple, what voice(actor, famous person,entity) would you like so much that you would pay to have your ghost sound like them. I personally picked Scarlett from the movie "Her".
Edit 1- ok we've had some good ones that have literally made me lol, the reoccurring ones seem to be John Cena, Snoop dogg and Arnold Schwarzenegger

I would go for Gordon, but that dude will just be an asshole to me so Imma go with Micheal Cera from the movie Super Bad. I wish Mcloving was up there haha.
