Voiceprints from the Sky

A two-year, $1.25 million dollar gift from the Kenneth L. Harder Trust will kick-start development of a new, faster system for analyzing hundreds of thousands of sounds—whether from the night sky or beneath the sea. The data will be used to improve our understanding of the migrations and population health of birds, whales, and other wildlife—and to help decision-makers minimize harm from energy development and other human activities. The new tools will “train” computers to look for specific acoustic characters to identify sounds—the “voiceprints” of migrating Wood Thrushes, American Redstarts, and Song Sparrows, for example.
