Audeo "Think N' Spell" neckband allows voiceless phone calls
What's funny is that the most exciting thought I had regarding this is that once (if) it works in real time, it could save me a lot of throat pain when I have to teach for extended periods. Just connect this to my laptop and plug the laptop into the classroom speaker system, all set.
That and it's an awesome way to interact hands-free with a smartphone without looking like a schizophrenic. Not that I have plans to get a smartphone before non-smartphones cease to exist.
