Today, we’re launching a new feature which will let everyone using Google Go’s browser listen to webpages out loud. Powered by natural language processing and speech synthesis AI, this technology can read aloud billions of webpages in 28 languages smoothly, and in a natural sounding voice, even on 2G connections. It also uses minimal cellular data. This technology relies on AI to determine which parts of a page to read, and which to leave out, so you only listen to what is important.

Hopefully this will come to more devices, I could see it being really handy on Chromebooks.
