NASA researchers can hear what you're saying, even when you don't make a sound.
Jorgensen, using an uncanny technology called subvocal speech recognition, demonstrates it at his offices at NASA's Ames Research Laboratory in Mountain View, Calif. He attaches a set of electrodes to the skin of his throat and, without his opening his mouth or uttering a sound, his words are recognized and begin appearing on a computer screen. The Ames lab has already used subvocal commands to drive a car around a virtual city in a computer simulation and to Google the Web using nothing but unuttered search terms and commands. Jorgensen sees abundant applications for his technology where audible speech is impossible: for astronauts, underwater Navy Seals, fighter pilots and emergency workers charging into loud, harsh environments.
When we speak aloud, we're forcing air past the larynx and tongue, sculpting words using the articulator muscles in the mouth and jaw. But these muscles go into action regardless of whether air is sent past them. All you have to do is say the words to yourself and you're sending weak electrical currents from your brain to the speech muscles. Jorgensen's trick is to record those signals (known as electromyograms), process them with statistical algorithms and compare the output with prerecorded signal patterns of spoken words, phrases and commands. When there's a match, the unspoken turns into speech.

"Integrity" and "integer" both contain a Latin root meaning "whole; complete." The root sense, then, is that people may be said to be acting with integrity when their beliefs, words, and actions have a sense of unity or wholeness.
OK, so if I had those things stuck to my larynx, you telling me as I read this post he would be able to "hear" me reading it in my head??? No frickin way!
Deja Moo: The feeling that you've heard this bull before.

Way... at least if you were saying a response to the post to yourself anyway.
Freaky!!!
If I accept the sunshine and warmth I must also accept the thunder and lightning.
