John Iovine's PIC Microcontroller Project Book, Chapter 7 uses the SPO-256 speech synthesizer chip as a basis for an interesting project. A more recent offering can be found in David Cook's Intermediate Robot Building, Chapter 18, which uses an LM386N-1 to drive a small (8 ohm) speaker. Cook discusses the system he developed to play tones and tunes. He provides sufficient information--about six pages--to roll your own. Cook uses the Motorola KX8 uC but adapting his method to a PIC should be trivial.

This sounds like a good project to experiment with.
