Rather than talking, Maggie is well known for producing a characteristic "sucking" sound from her pacifier. This sound effect was originally provided by the show's creator Matt Groening, for early episodes of The Tracey Ullman Show, and also by Gabor Csupo (who was also the animation executive producer, for the first 60 episodes). The sucking noise is heard in all of Maggie's appearances to date, and is usually archive audio from either of Groening or Csupo's initial recordings (from the show's early episodes). Other than her sucking noise, Maggie has been known to make other noises, such as occasional squeals and babbling. In most instances, these vocalisations are provided by either Nancy Cartwright or Yeardley Smith.
