I find most spoken audio very comfortable at double speed. Whether this matches reading speed depends on your reading speed. I also find spoken audio less fatiguing than reading for most fiction and most popular nonfiction. I am less prone to being derailed from the book. This is where I read for a bit and then find something else more compelling, such as a blog or a rationalist forum, or where I pick up the book and then put it back down having resolved to continue tomorrow. Even if reading-time is shorter when I read, calendar time is often very long.

For those who want a program that does this well, I find that "mplayer" is decent at speeding up the things it plays. '[' and ']' alter the speed, and the intial speed can be set with eg. "-speed 2.0" on the command line, though I find that too fast.

One generally wants to correct for pitch changes with the "scaletempo" audio filter. This can be enabled with "af=scaletempo" in a config file, or "-af scaletempo" on the command line.

(One can also use the "mencoder" version of this to create sped-up files for use on other devices).

Audacity also works for this purpose.
