Over the course of millions of years, human voices have evolved to hold startling power. These clouds of vibrating air carry crucial information about who we are–and we rely on them to push ourselves up and out into the physical world.

This week, we’re on a journey to understand how we got our unique sonic fingerprint, the power it affords us, and what happens when it’s taken away.

Special thanks to Alice Wong, Wren Farrell, Hector Espinal and his parents, Crisaly and Hector Espinal, Mary Croke, Nancy Kielty, Beth McEwen, Robin Feuer Miller, Roomful of Teeth, Amanda Crider, Caroline Shaw, Judd Greenstein, Leilihua Lanzilotti, Rebekka Karijord, and Michael Harrison.
