Research conducted by Dr. Janice Light and team with the AAC-RERC (Rehabilitation Engineering Research Center) has found that some people benefit from the display of animated text to accompany the spoken word when speaking with a communication device. The animated text catches the attention of the individual and helps them make the link between the text with the word being spoken. The study has found that this interaction can help the individual associate the written and spoken word, thereby being a step toward literacy.
