Re: Sounds like a good way to go insane
Sure, it is fine if you want to communicate basic stuff like telling a cab driver where to take you, or him telling you how much you owe
If it does this well then this could be enough to create and own a new market and it will, of course, vastly increase Google's training materials. There are lots of people who travel to countries where they don't speak the language.
I'm more disappointed by the battery life: my Jabra Sport does 15 hours but these would be more comfortable with the cord. But some kind of pendant with battery and controls would be my preference (like my old Sennheiser)
