Teen Talk Barbie is an edition of Mattel's Barbie doll, introduced in 1992, that incorporates a voice box programmed to speak one of four randomly selected phrases when a button is pushed. It became controversial because one of the spoken phrases was "Math class is tough", and was also later used for a protest wherein some dolls had the voice boxes exchanged with those for Talking Duke G.I. Joe action figures produced by Hasbro.
