To study mouse vocalizations, the team gathered data as groups of four mice — two males and two females — interacted.

Starting with the enormous amounts of ensuing video and audio data, the researchers then used machine learning A.I. to develop a system that’s able to connect specific sounds with distinct animal behaviors.
