European scientists develop AI to interpret pig sounds, detecting free-range pigs' lower stress levels.

European scientists have created an AI algorithm that interprets pig sounds to enhance animal welfare on farms. By analyzing thousands of recordings, the tool detects emotional states through various vocalizations. It found that pigs in free-range environments exhibit fewer stress calls than those in conventional settings. This innovation could lead to farm labeling, aiding consumer choices and allowing farmers to monitor their pigs' emotions via a mobile app.
