Who voiced the ship's computer on the Axiom in WALL-E?

Sigourney Weaver voiced the Axiom’s ship computer in WALL-E.

The computer is a calm, helpful voice heard aboard the Axiom, where automated systems manage nearly every aspect of human life. Weaver’s performance gives the ship’s interface a warm, familiar personality, contrasting with AUTO, the starliner’s red-eyed autopilot and the film’s principal mechanical antagonist.

The casting carries an intentional science-fiction connection. Weaver played Ellen Ripley in Alien, whose spaceship computer is named Mother. WALL-E director Andrew Stanton joked that Weaver was getting to be “Mother” again when he offered her the role. In WALL-E, though, the character is credited as the Axiom’s computer rather than Mother.

A common mix-up is attributing AUTO’s voice to Weaver. AUTO’s speech comes from MacInTalk, Apple’s text-to-speech program, and its deliberately flat delivery reflects AUTO’s rigid obedience to Directive A113. Weaver’s computer voice is separate: she serves as the ship’s general computer, while AUTO handles navigation and command functions. This distinction makes the final conflict between the captain and the autopilot easier to follow.
