In the 1951 film, which actress provided the voice and live-action reference for Alice?

Kathryn Beaumont provided Alice’s voice and live-action reference for the 1951 film.

Beaumont was a British child actress whose performance shaped both the character’s voice and the animators’ understanding of Alice’s movement and expressions. Disney used live-action reference footage as a guide for animation, allowing artists to study timing, gestures, posture, and acting choices before translating them into drawn scenes.

Alice was Beaumont’s film debut. She later voiced Wendy Darling in Disney’s Peter Pan, released in 1953, making her one of the studio’s most recognizable child voice performers of the period. Her connection with both characters helped establish the youthful, composed vocal style associated with Disney’s early animated heroines.

The role is sometimes confused with later live-action portrayals of Alice or with other Disney performers. Beaumont did not merely provide a temporary reference track: she supplied the finished voice performance and served as the visual reference for the animated heroine.
