What if we could hear nature's ultrasonic communication -- and talk back? From a bat's shrill speech to a peacock's infrasound mating call, conservation technology researcher Karen Bakker takes us through a sound bath of animal noises that are far outside humanity's range of hearing, demonstrating how artificial intelligence has translated the incredible complexity of nature's soundtrack. She asks us to consider the moral weight of such transformative technology and explores the futuristic opportunities presented for conservation, interspecies communication and more. The TED team is saddened to share that Karen Bakker passed away in August 2023. We’re grateful for the opportunity to uplift her work.
