Nothing else than the Listen & Learn Nursery Rhymes introduced already in 1990.

Dismantling this 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/CSM11159: 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

The Magic Melody plays 6 monophonic melodies and 6 sung German children songs using a the TSP50C11 single-chip speech synthesizer. The songs are selected by rotating the ball in a way that the picture of the selected song faces up.

6 monophonic, short German children song melodies:

Ein Männlein steht im Walde
Hänschen klein
Auf einem Baum ein Kukuck sass
Backe, backe Kuchen
Der Mond ist aufgegangen
Spannenlanger Hansel


6 sung German children songs:
(unfortunately very short, only 1 stanza per song)

Alle Vögel sind schon da
Kommt ein Vogel geflogen
Alle meine Entchen
Häschen in der Grube
Es tanzt ein Bi-Ba-Butzemann
Fuchs Du hast die Gans gestohlen

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.
