I'm bad at the role playing part, suggest a character or trait to separate the P from the C

Title. Friend group and I play regularly but most of us are bad at the role playing part of it to the point where it's hard to tell when the player or the character are speaking in some scenes. Conversations are stiff. We can't use too heavily modified voices because we're playing remotely. My character is about to die (probably!) so help me pick a character or trait of my new character that someone not comfortable roleplaying can stick to without feeling weird about it!
