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

Gordon Ramsey would be good, as well lol. "You've woken the Hive! Great job, you bloody dumb bastard!" "Guardian down! Already? You suck!" *after Little Light comment* "Call me that again and you'll be in more pieces than a freshly chopped onion, you colossal idiot!" *finds Dead Guardian on Moon* "Where the **** is his Ghost?! It vanished faster than my appetite when you made that steak! ....Too soon? **** off!"
