Thanks a lot! I expected the samples to be hard to understand, but this is absolutely mind blowing.

Any sighted around here who managed to improve their ability to understand fast speech?

I routinely listen to podcasts at 2x while doing other things, and can go up to 3x if it's quiet enough (or a slow enough task) to focus. I'm willing to bet I could do it faster if I was doing nothing else.
