In 2009, Susan Boyle's debut roused Simon Cowell from his grumbling slumber on the television show Britain's Got Talent and viewers across the world rallied to the side of the unemployed, older woman with the voice of a trained Broadway star. In Mismatched Women, author Jennifer Fleeger argues that the shock produced when Boyle began to sing belies cultural assumptions about how particular female bodies are supposed to sound. Boyle is not an anomaly, but instead belongs to a lineage of women whose voices do not match their bodies by conventional expectations, from George Du Maurier's literary Trilby to Metropolitan Opera singer Marion Talley, from Snow White and Sleeping Beauty to Kate Smith and Deanna Durbin. Mismatched Women tells a new story about female representation in film by theorizing a figure regularly dismissed as an aberration. The mismatched woman is a stumbling block for both sound and feminist theory, argues Fleeger, because she has been synchronized yet seems to have been put together incorrectly, as if her body could not possibly house the voice that the camera insists belongs to her. Fleeger broadens the traditionally cinematic context of feminist psychoanalytic film theory to account for literary, animated, televisual, and virtual influences. This approach bridges gaps between disciplinary frameworks, showing that studies of literature, film, media, opera, and popular music pose common questions about authenticity, vocal and visual realism, circulation, and reproduction. The book analyzes the importance of the mismatched female voice in historical debates over the emergence of new media and unravels the complexity of female representation in moments of technological change.
