Ask HN: Correctly pronouncing equations in CS papers

I try to read a few papers a month (like the Bigtable or Chubby ones) to stay current with what the state of the art. But, I frequently find myself stumbling over the right way to "pronounce" the equations in my head. I imagine most people learn this sort of thing by listening to a professor read them out loud in class. Does anyone know an online resource for this?
