There's a lot of exaggeration and unfounded declarations regarding subjective things on the internet, but Sulu actually does have the coolest voice on Earth.
If you watch Trekkies, everyone else is kissing Trekkie-Ass (because the conventions and autographing will pay for their houses with no need for actually having a viable acting career) but Sulu is recounting the story of the first Trek convention and the way he says, "So these...people, are paying to fly me out, and got me a nice room, and food, and I'm...thinking, "These people are FOOlish.".
You can't type it, just watch Trekkies and you'll see. These people are FOOlish.
