How to spot a deepfake: the maker of a detection tool shares the key giveaways

Sometimes there are no background noises when there should be. Or, in the case of the robocall, there's a lot of noise mixed into the background almost to give an air of realness that actually sounds unnatural. With photos, it helps to zoom in and examine closely for any "inconsistencies with the physical world or human pathology", like buildings with crooked lines or hands with six fingers, Lyu said. Little details like hair, mouths and shadows can hold clues to whether something is real. Hands were once a clearer tell for AI-generated images because they would more frequently end up with extra appendages, though the technology has improved and that's becoming less common, Lyu said.
