The best female vocal aging I think comes from the cartoon "Grossology" in the episode "Oldie but a Goodie." It is perhaps the best female AP cartoon also - period. You actually hear Abby's voice change from that of a young teenager into sounding "Like her Mom" at around the 8:00 mark. Then later you hear her voice change into that of an old woman. The cartoon progression too is also awesome form young girl to adult to middle-aged adult to matron to old woman. Check it out.
