There are various tools for speeding up audio while leaving it listenable. The tool to use depends on your platform, but you can find quite a few options by Googling.

I use VLC to listen to audio and watch videos at about 2x speed. VLC has keyboard shortcuts to change the speed and pitch gets adjusted automatically. Keypad + or - to change speed in increments of 0.5x and "[" or "]" keys for increments of 0.1x
