A computer accustomed to your accent may recognize your words from lapel or headset microphone input better than a stranger a meter away.
The computer is built into a backpack that connects to your sweater, which has a flexible black and white display* on the front. After a slight pause, the computer instructs your sweater to subtitle your sentence so that others can verify what they might have missed.
Inside the backpack a control panel has an interface for computer-generated translation and display options.

These microspheres and electromagnets mount to some flexible material.-- Ketchupybread, Apr 27 2009 Thesis a one duffle-eyed ear!-- MaxwellBuchanan, Apr 27 2009 [+] Make it a T-shirt, though - a sweater is a bit much in a noisy nightclub.-- moomintroll, Apr 28 2009 <squints through the cloud to read sweater>
WHY IS THAT WEIRDO STARING AT MY TITS?-- theleopard, Apr 28 2009 Display the subtitles in cyrillic, to give yourself a pirated look.-- loonquawl, Apr 28 2009 Yes, some of the proposed forms of electronic paper would do this. I'm rather keen on the system that uses spheres that are half-black, half-white and whose orientation can be controlled.
When you're not talking you could set it to display your favourite Twitter feed.-- Aristotle, Apr 28 2009 random, halfbakery
