Those are images that capture the amplitude, frequency, and duration of the sound. Instead of cracking the problem by teaching computers to identify the actual sounds, researchers at the Cornell Lab trained Merlin to recognize the visual patterns of each bird song based on spectrograms. This would have seemed like a daunting challenge only a few years ago. “Having this incredibly robust bird dataset - and feeding that into faster and more powerful machine-learning tools - enables Merlin to identify birds by sound now,” he said. “Thousands of sound recordings train Merlin to recognize each bird species, and more than a billion bird observations in eBird tell Merlin which birds are likely to be present at a particular place and time,” said Merlin’s project coordinator Drew Weber. Merlin’s pioneering approach to sound identification uses AI technology powered by tens of thousands of citizen scientists who have contributed their bird observations and sound recordings. A bird call identifier powered by thousands of volunteers Merlin can now help you identify more than 400 bird species by sound throughout the United States and Canada with more species and regions are being added soon.Ī previous version of the app was able to identify 7,500 species based on photos or descriptions. Even if multiple species are singing at once. By just holding up your phone towards the sound, Merlin listens with you and uses AI to identify the species. The free Merlin Bird ID app, made by the Cornell Lab of Ornithology, makes a quantum leap in bird identification.
