Use an ISD1700 chipcorder from Nuvoton. Add a beam break circuit from any number of instructables ! One chip, one photo detector, one light emitting diode. , three resistors...

I'm sure there are other ways but it could be accomplished with an Arduino, THIS project, a speaker, and the light beam system. When the Arduino senses the beam is broken it triggers the audio.
