I'm impressed. I often get my Mac to read things to me as I find it difficult to follow text. This was great.
I'm a big, no HUGE, fan of the Mac Text to speech thing. It's great for proofreading text, and reading non-code text. @achalkley what speed do you use? This is where I have mine: http://i.imgur.com/nIO0gRw.png It's a little quick, but it keeps thing interesting ;)
Mine is a little slower than yours - http://i.imgur.com/WGW1QWk.png - I use cmd + alt + shift + s as my short cut.
