DefinitionA deepfake (ディープフェイク) is fake video or audio that uses deep learning to synthesize a person's face or voice, making it look real that they said or did things they never did.
ExplanationBecause it is made by training AI on the features of the person's real video or voice, it is hard to tell apart by looks or sound alone. It can be misused for fraud by impersonating the person, or for spreading false information.
AnalogyIt is like someone else wearing a costume that looks exactly like a person and speaking as them. The closer the likeness, the harder it is to see through.
Memory hookDeep (deep learning) + fake (forgery). The name itself says how it is made and what it is for.
