I listen to books and articles via text to speech application for over 3 years. Currently i am able to listen comfortably at 3.6x speed. I don't know how to test comprehension through. My friend says i might be able to think faster than other people, because of superhuman listening powers i now posess. Don't know how to test that either.
I have made a browser extension that helps me put every webpage I read through TTS. I also get current word highlight on text and automatic page scroll. It helps me focus twice as good, I can't even stand reading without TTS support any more.
Unfortunately I can only stand one voice - "Alex" from OSX, at about 1.3x ... 1.5x speed. Other voices I find irritating. I'm following the new WaveNet TTS voices with great expectations, but they don't seem to come near my laptop.
