Abstract
A self-reading electronic child's book that displays a sequence of indicia, such as words, and having under each indicia a visual indicator such as a light-emitting diode with the visual indicators being automatically illuminated in sequence as the child touches a switch associated with each light-emitting diode to sequentially drive a voice synthesizer that audibilizes the indicia or word associated with the light and switch that was activated.
