<P> Jane was voiced by Penny Singleton in all of her appearances up until the feature film . After Singleton's death, Jane has been voiced by a number of different actresses, including Laurie Fraser (The Jetsons: The Best Son), Diane Michelle (Harvey Birdman, Attorney at Law), Beth Littleford and D.D. Howard (Family Guy) and Grey Griffin (The Jetsons & WWE: Robo - WrestleMania!). </P> <P> She was included in Yahoo!'s Top 10 TV Moms from Six Decades of Television . </P> <P> Judy Jetson is the 16 - year - old daughter of George and Jane Jetson who acts just like a normal teenage girl only with more futuristic tastes . </P> <P> Despite Judy still keeping modern - day "teenage girl" likes and dislikes, such as seemingly never - ending conversations on the telephone and shopping for futuristic outfits, she does not live exactly like a modern teenager, obviously because of the time the show takes place, because she enjoys taking advantage of the many gadgets at her grasp because of the technology (like controllable zero - gravity switches made for accomplishing popular dance moves of the show's time or for other uses). She also gives a summary of how her day went including her problems to a floating robotic diary, appropriately named, "DiDi" (voiced by Brenda Vaccaro). </P>
