This funny synthesizer based product from Texas Instruments generates a lot of different sounds and stores them into internal memory. 

SpeaknMusic_PCB.jpg (69312 Byte)Compared with earlier products of the Speak & line this one uses a quite simple technology. 

This educational toy was rated by Texas Instruments for children aged between 7 and 11 years.

A similar product was introduced in the same year with the Little Maestro and two years later with the German speaking Music-Star. The Speak & Music sold in United Kingdom differs from the design, view it here

The La Musique Magique introduced a French speaking version, Fonillo Suonaparla an Italian voice.

Other products in the Speak & line cover spelling and reading words. Compare this Speak & Music with Speak & Math, Speak & Spell and Speak & Read.

Dismantling this Speak & Music manufactured in June 1987 by Texas Instruments in the United States reveals a compact design centered around just two Integrated Circuits:

TMS50C40/CM54129: TSP50C50 VSP (Voice Synthesis Processor) with with 8-bit microcontroller and 8k Bytes Mask ROM for both program and voice and 32 Bytes RAM
CF60034: Not yet discovered, probably a Port-Expander for the VSP

Developed for children, the Speak & Music found – like the Speak & Spell – its way into the Detroit area electronic music. Artist Dethany (tOYBREAKER :::) heavily modified this kids’ keyboard and created this wonderful “Bloo Meanie”.
