I am confused how they had enough data to recreate a voice. The whole process seems a bit like a guess rather than a conclusion.
LONDON (Reuters) - Further research into Neanderthal speech using fossil evidence from England and a computer synthesizer has uncovered what scientists believe to be a complete simulated conversation between two cavemen... Caveman 1: I say good sir that looks like a rather plentiful supply of fertile females you have over there. Would you be so kind as to allow me to hit one of them over the head, drag them by their headly hair and have them settle in my tribe? Caveman 2: Please, there's no need to ask, be my guest. It would be a truly great honour sir. To have one of my females settle in your tribe shall make for a strong alliance and will bode well for future business and political negotiations. Caveman 1: These are my thoughts exactly good sir. The tribesmen shall be overwhelmed by your generosity.
if a caveman and a cavewoman are playing truth or dare, the man would probably dare the woman to do something like throw a flaming stick at a monster, so she would be like "truth" and he would say "what's your biggest fantasy?" and she would be like "agriculture" -Eugene Mirman
