Our voices are about as unique as fingerprints — similar instruments, but with endless variations. As humans, we each essentially produce sound in the same physiological way, but it’s not as simple as plucking a guitar string. And when we talk we’re dropping clues about who we are, what we do, and where we’re from. A dialect can hint where a person is from. An expressive range might suggest a person is a singer or actor. A slow and quiet tone could mean a person is feeling sad or tired. Check out the video above to learn more about the ins and outs of how we produce sounds and why no one else sounds like you.
