Or more accurately, the french language version of the Speak & Spell - "La Dictée Magique".
The Speak & Spell has a speech synthesiser at its core, so it's not difficult to extract all sorts of weird and wonderful sounds out of them by disrupting the electronics.
I loosely based these bends on the Speak & Spell "Incantor" blueprints by artist Reed Ghazala.
