Artificial intelligence is being used to better understand our friends in the animal kingdom. University of Michigan researchers are using AI to decode the vocalizations of dogs, studying whether their barks convey aggression or playfulness. Interestingly, the researchers are using speech models originally trained on human speech to find patterns and better understand how they’re communicating. Similarly, an initiative called Project CETI is using machine learning to learn more about how sperm whales communicate with another.
