Revan..... actually is there a non speaking person besides morgan free(no wait he said prepare for unseen consequences)....
ok so is there actuall a such thing as a non-speaking character because most of the characters on the list talk.
Jak - talks in 2-X but hey - hunsha? Could mean I kick you in people without tongue language.
Mario, Link, dog - there will be brawl and apocolypse lane.... hahaha no, some gunts and noises (or barks) but you said mario no grunts so i quote "its a me mario"
Yoshi - like all pokemon, he can say his own name.
Red - red was suppose to be the game version of Ash from the TV show and also in the staduim games for the n64 he says "I choose ...." but if your gonna get on my ass that its red as in red/blue well then he takes the cake for video game shut up because well no one except the pokemon talk in that game. Well almost everyone, maybe some of the people who sit around all day waiting to make a b line torwards someone, but can your really identify them as people.
But from the list I'm going with Jak.... props to mario and link but I don't think of link as a person anymore, just some tale about a her who save a princess but unlike mario the story changed everytime. its like a bed time story told through the ages, people tend to for get the details.... monsters, towns, timetravel, aliens, TRAINS!
Mario was more like a game to pass the time, I have a princess and .... Ok I can't resist.... we had a fight last night and I need you to kid nap her and set a challenge in head of me knowing that I can do it, so that I can save her and she won't be mad at me.

P.S. I will own you biznitchs in tennis today, yu may have won on the tracks but we will have our revenge wuahahahahahahaha.
