Seth MacFarlane voices four of the show's main characters: Peter Griffin, Brian Griffin, Stewie Griffin and Glenn Quagmire. MacFarlane chose to voice these characters himself, believing it would be easier to portray the voices he had already envisioned than for someone else to attempt it.
Although there are a few choice instances where the family can hear Stewie. Prompting Stewie to say, Oh, so NOW everyone can understand me?!. And in another episode, Brian and Stewie are about to talk to Cleveland's ex-wife and they are discussing whether or not she is one of the characters that can understand Stewie.
