Mattel announced its digital assistant-powered smart speaker for kids, Aristotle, this past January. The Echo-style audio device was set to offer baby monitoring, games, facts and sounds to help soothe your children. Mattel promised it would be able to learn your children's voices, too, and grow with their speech development. We caught a glimpse of Aristotle at CES this year, where we learned that the toy company created a custom AI engine with "natural language processing" to learn how your child pronounces words. According to a report at The Washington Post, the toy company has now canceled the device amid concerns of privacy and the role of technology in child development and parenting.
