She speaks in a slurred manner due to the fact that she wears headgear. Shelley has an extremely aggressive temper and has very little respect for Stan and his friends, usually referring to them as ' turds'. The character was voiced by Mary Kay Bergman until Bergman's death, and Shelley has subsequently been voiced by Eliza Schneider. Shelley Marsh is Randy and Sharon's daughter and Stan's older sister. Sharon was originally voiced by Mary Kay Bergman, later Eliza Schneider, and is currently voiced by April Stewart. Sharon has also been represented as an overzealous parent, such as when she kidnapped Officer Barbrady after he came to investigate the disappearance of those Sharon had buried in her yard because she mistakenly thought they were Stan's murder victims. She is referred to by the name 'Carol' in the episode 'Death' when Sheila Broflovski hands her the phone at the protest with Cartoon Central. She has close-cropped brown hair, and wears a brown long-sleeved pullover adorned with red ruffles at the cuffs and collar, and dark blue pants. Sharon has never been portrayed in a work capacity on the series, but was depicted as the receptionist at Tom's Rhinoplasty, a local surgical clinic, in South Park: Bigger, Longer & Uncut and South Park: The Stick of Truth. Sharon Marsh ( née Kimble) is the wife of Randy and mother of Stan and Shelley.
