Nothing else than a Touch & Tell with Italian voices stored in the Speech-ROM.
The Libro Parlante was distributed in the 80s like some other Texas Instruments products by Clementoni.
The pictured Libro Parlante was manufactured already in 1982 and makes use of a simple approach: The printed circuit board (PCB) is identical with the Touch & Tell introduced one year earlier but lacks the Speech-ROM. Instead of it the Expansion Port of the toy is populated with a small, white module.
module looks like the well known Expansion-ROM's of the original Touch &
Removing the cover of the module reveals with the TMC0350 (CD62176) the well known Voice Synthesis Memory (VSM) family introduced with the first version of the Speak & Spell. The "Custom Design 62176" holds obviously the Italian voice of the Libro Parlante.
Later models of the Libro
Parlante include the same Speech-ROM on the main printed circuit board
The next evolution step is the more advanced SuperLibro Parlante.
