In this April 4, 2013 photograph, Colton Smith, left, uses a combination of sign language and Google Translate on his iPod to "speak" with his new 14-year-old sister, Guan Ya, in the dining room of their Rienzi, Miss., home, as parents  Phillip and Niki Smith listen. The Smiths and their three other children are using the program to communicate almost exclusively with Guan Ya, who is deaf. The family uses iPhones, iPods and a laptop, all loaded with the program to write in either English that translates to Chinese or vice-a-versa. (AP Photo/Rogelio V. Solis)
