ABSTRACT:
A combination of a book with an audio device includes a book and an audio device attached to the back cover of the book for audibly reproducing predetermined text printed on the pages. Different identification labels are attached to the end edge of the pages. These labels are composed of an insulation tape with an U-shape conductive stripe printed thereon which is different for each page. The audio device includes a ROM memory having the spoken messages corresponding to the printed text on the pages pre-stored therein in digitized form. Other electronic components for audibly reproducing the spoken message are included. A contact plate pivotally secured on a lower section of the audio device contacts the identification labels on the book pages. A plurality of parallel disposed conductive stripes on the inner surface of the contact plate connect to the respective electronic components of the audio device. Transient engagement of the contact plate with the identification label will trigger an identifying trigger signal to extract a spoken message from the ROM memory corresponding to the printed text on an open page. The spoken message is audibly reproduced through a speaker so that the user can hear with he is reading.
