This is what goes on behind the scenes whenever you open your mouth to speak.

The image was captured at 50 frames per second over 20 seconds with a rapid-fire X-ray camera. It's part of speech researcher Christine Ericsdotter's work to precisely capture and build a computer model of the intricate movements of the tongue, lips, pharynx and jaw during speech.

If you're curious, the word being said here is "pion," Swedish for "peony."

It is interesting to see how relatively inanimate the skull and jaw really are in speech. All of our flesh seems to flow around the skull like water.

--GTO--

p.s. the tongue is a devil serpent waiting to attack

She has a over bite! Maybe she sould think about correcting that. lol
But this is really cool video.

I know this is random, but is the person saying "butterfly"?

Not sure if I want a 1000 X-ray images taken of my skull over a 20 sec. period. Isnt that dangerous??

Old news. You can get better videos anywhere - and the real interesting ones show the action of the vocal folds vibrating, which you need a strobe light to record.

@John Mahoney thanks for some of the least interesting articles on PopSci to date. The rest of you writers - take note! lol

My son-in-law Armando Ambid Lorenzo, M.D. who is a diplomate in Ear, Nose, Throat Head and Neck Surgery will be very interested in these developments.

"50 frames per second over 20 seconds" means 1000 X-ray shots in 20 seconds.
I will not take this doze of X-ray radiation exposure myself. :-(

Read ALL the text. "pion" Swedish for "peony".
Of course, Swedes talk funny, so it's hard to tell. ;p
