Deepfake
In short: A deepfake is AI-generated media that replaces one person's likeness with another, which is fundamentally different from AI lip sync that modifies only mouth movements on the original speaker.
About Deepfake
The term deepfake typically refers to face-swapping technology that replaces an entire person's face with someone else's likeness, often without consent. AI lip sync is a distinct technology that only modifies the mouth region of the original speaker to match new audio, preserving the person's identity and appearance.
This distinction is important: legitimate lip sync applications like video dubbing and localization modify the speaker's own mouth movements to match translated audio, while deepfakes replace identity entirely. Responsible AI lip sync platforms prioritize transparency and consent in their usage policies.
How Deepfake Connects to Lip Sync
Deepfake relates to several other concepts in the AI lip sync pipeline: Facial Reanimation , and Neural Rendering .
