Is there any way to output a short voice audio message from a PIC without
needing a D/A?  Is there any way to imitate this using other hardware or
maybe using tricks in PWM output?  I ran across some brief info on the
PICLIST, but haven't been able to get a lock on exactly what to do.

I'd assume that maybe 3-4KHz would be enough, and the message could possibly
fit in a 16F876 or similar.  I could sample the message input to the PIC
from the A/D through a mic and store the table in program memory (plus I
could probably get away with packing it into 2 7-bit values due to the
relative low quality required).  The output, though, is where I need help.
