Audrey Hepburn Vocal Challenges in My Fair Lady

Hepburn came from a strong dance and acting background, but the film required operatic precision for pieces like "Wouldn't It Be Loverly" and "On the Street Where You Live." Directors acknowledged that her natural speaking voice was not suited to the demanding Broadway score without substantial support.

This limitation led to extensive vocal coaching and the decision to use a professional singing double. The team prioritized musical quality and continuity over showcasing Hepburn’s untrained voice, setting the stage for the casting of a specialized vocalist.

Marni Nixon, known as the ghost singer for many leading ladies in Hollywood musicals, provided nearly all of Eliza’s sung lines. She matched Hepburn’s gestures and facial expressions during filming to ensure seamless synchronization.

Her involvement preserved the emotional intensity of the Lerner and Loewe material while allowing Hepburn to focus on performance and physical portrayal. Nixon’s background in musical theater brought authenticity to the character’s transformation.
