Why do our voices sound different from each other?
Your Voice Symphony
Why do our voices sound different from each other?
Stand in a crowded room and close your eyes. You can still tell who's speaking — your friend's voice is smooth and low, your sister's is bright and quick, the teacher's rumbles like distant thunder. What makes each voice unmistakably theirs?
Every voice starts the same way: air from your lungs rushes past two small folds in your throat called vocal cords. When they snap together and apart super fast — hundreds of times per second — they chop that air into vibrations. That's the buzz that becomes sound.
