Listen for mismatches in lip-sync, audio quality and cadence When audio and visuals don’t align, such as lip movements not matching speech, delayed head turns, or a robotic-sounding voice, you may be witnessing a manipulated file. Deepfake audio may lack natural pauses, emotion or rhythm, and speech might feel monotone or rehearsed. If something sounds ‘off’, even if the image looks convincing, treat it with caution. Scammers rely on our trust that what we hear and see naturally link up, so you must test that assumption.
