Glasses which 'hear' a foreign language and automatically translate what's being said, before beaming it onto the lens, have been revealed.

NEC say their Tele Scouter glasses will let a wearer see exactly what people around them are saying, even in other languages.

It features a microphone and camera which record foreign languages before converting it to text and running it through a translation computer worn on the wrist.

The translation is them beamed onto a tiny retinal display for the wearer to read what was just said - the entire process happens in a fraction of a second.

Does this mean Brits will just start reading slower and louder?
