Ever since the times of Ancient Greeks, humans have been wondering if dolphins have “language” or at least some sort of sophisticated communication system. This project will bring us a little closer to better understanding what information dolphins’ calls could possibly convey. Additionally, the utilization of deep learning models allows us to process a lot of data, something that has not been possible up until relatively recently. Accurate identification of dolphin sounds will allow better performing passive acoustic investigations as we will be able to identify if dolphins are visiting certain areas based on their acoustic signals alone.
