The human brain can interpret speech at a much higher speed than
people can speak clearly. There are devices that speed up voice
(essentially by stealing chunks of it, so that it doesn't increase in
pitch) and they are still understandable at much higher than normal
speeds. I wonder if there's a better algorithm that might be practical
today.
