You can buy a cheap voice recorder/player device.
Design the circuit to trigger the playback.
Connect to amplifier to make the voice louder.

Try the winbond ws701, it "translate" ascii input to speach...so from the microcontroller ascii stream to speech..whatever you like. Or ISD1020 chip that can record and playback sound. you can record several samples and play them back by selection true 8bit port
