Small toddlers use the Listen & Learn toy like a small ball. Due to the flats on each side the toy will find a stable position and play a sound associated to the Farm Animal on top of the ball. The Listen & Learn uses again Texas Instruments speech technology introduced with the Speak & Spell.

Dismantling a similar Magic Melody manufactured in 1992 by (or for) Texas Instruments in China reveals a technology very similar to the various Touch & Talkies. The design of the Magic Melody Tell is centered around a TSP50C11 Voice Synthesis Processor (VSP) and makes use of just one Integrated Circuit:

TSP50C11/CSM11XXX: TSP50C50 VSP (Voice Synthesis Processor) with 8-bit microcontroller and 16k Bytes Mask ROM for both program and voice and 128 Bytes + 16 Nibbles RAM

Each year another Listen & Learn theme appeared shortly before Christmas:

1989: Farm Animals
1990: Nursery Rhymes
1991: Sounds we Hear
1992: Sounds of Christmas

The toy is intended for toddlers ages 6 to 36 month.

Other toys for toddlers are the Peek-A-Boo Zoo and the Magic Sorter.
