It probably uses the UM5100 voice processor IC from United Microelectronics.
This will digitise, compress and record speech into an attached SRAM, and
subsequently play it back.
It needs a certain amount of analogue support circuitry, mostly for recording
- a playback-only unit is a lot simpler. The only additional digital device
it needs is the SRAM.
