Its  silver transistor-radio-like case contained complex LSI circuitry with 3 SMD ICs (likely clock CPU, speech CPU and sound IC), producing a Speak&Spell-like synthetic voice.
The silver transistor-radio-like case held intricate LSI circuitry with 3 SMD ICs (likely a clock CPU, speech CPU, and sound IC), generating a synthetic voice comparable to that produced by a Speak&Spell device.
