A talking book including a power source, switches, voice chips and speaker, all of which are mounted within the book and act together to "read" the words written on pages of the book. The switches are pressure-sensitive types, and marked areas on the pages are pressed in order to activate the switches and the chips in order to produce words or other sounds.
