Fortunately, though, it is quite rare to absolutely recent your voice or others for that matter. I can't seem find a logical explanation why this is. It ruins your imagination? I like to hear my character's voice and I felt that my character squealed and scream too little in previous games, but yay, we've got shouts.
I just prefer my character to be silent in RPGs. To me it's almost as essential as being able to customize how your character looks. Sure, if the developers pick a set look for you (like Rockstar did with Red Dead Redemption) most won't have any problems with it, but it's taking away an element of player freedom.
An example of an RPG with a fully voice-acted player-character which really irritated me is Two Worlds II. I hated my characters voice. It dictated the personality of my character completely, making them an American with a smug attitude. They may as well have given the character a name and a set appearance because the voice had already taken away the freedom to make a character as I wanted.
I want a character that has a fully customizable appearance, no voice, no background story which might give away personality (something Bethesda are good at and are maintaining with Skyrim), no name until I pick one, etc. etc.
