Kristen Bell can't stand her voice.

The 'Couples Retreat' actress dislikes the way she sounds when she speaks and does everything she can to avoid hearing recordings of herself.

She said: "I can't even hear it on an answering machine. I throw the phone across the room. It's too high-pitched. I hear it all day, every day, so I'm over it."

Kristen comes from Michigan, and dislikes the way her accent becomes more exaggerated when she is around friends from the area.

Despite disliking her voice, the 29-year-old actress wouldn't change her upbringing.

She is currently dating actor Dax Shepard, who is also from Michigan, and thinks their bond is particularly strong because they are from the same place.

She explained to the USA Today newspaper: "I think that's why we get along so well. We were raised the same way. We're both very aware that this could evaporate in an instant and you better have a back-up plan, and I'm not talking about career. I'm talking about sanity."
