This X-Ray Video Shows the Inside of Your Mouth as You Talk (Video)
German researchers posted an X-ray video of what the inside of your mouth looks like when you talk. They used MRI technology to film a man from the side as he says a few sentences, and then some vowels, consonants, and numbers.
It's kind of like looking beneath the skin. You see all the different muscles and tissues working together like the lips, tongue, and larynx. Even though he's speaking in German you still get it.
