Why your voice sounds different on a recording

By Casey Frye, CCNN Writer

The first time my mom got a camera, my sister and I went crazy recording every little thing we did throughout the day. Heck, we even went so far as to make our own short films. The thing was, when we replayed all the videos, I didn’t sound like myself! Why was this?

Ben Hornsby, a professor of audiology at Vanderbilt University, says it’s because I hear the vibration my voice creates in my head plus the actual sound it makes.

“When you speak, the vocal folds in your throat vibrate, which causes your skin, skull, and [mouth] to also vibrate, and we perceive this as sound,” he explains. “The vibrations mix with the sound waves traveling from your mouth to your eardrum, giving your voice a quality that no one else hears.”

Since the camera could only record the sound of my voice, and not the vibrations, the recording of my voice sounded a little different!
