I often listen to talks at faster speeds, but there's a trick to it: ramp the speed. Start at 1x, then increment the speed slowly over a bit of time giving your brain time to adjust. You can easily get to 3x speed by "ramping" the speed over a period of time. Is there any audio book reader that supports such speed ramping? In an automatic way?
