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.
