You could use the ISD Analogue recording chips for that.
Very easy to put together, not even a micro needed,
just a small ammount of CMOS logic, if that.

The ISD chips can have several short messages recorded,
for replay at the press of a button.

Or any of the kid's toys that record and replay sounds?
