An AI talking head video is a clip where a human-like character faces the camera and speaks on behalf of your brand, course, or channel. Instead of recording on set, you start from a digital persona (trained from reference photos or a template), provide a script or narration, and let generative models animate the face so lip and jaw motion track the audio.
The phrase covers everything from simple lip-sync on a still portrait to fuller motion where the model keeps identity stable across takes. Marketers often use the format for spokesperson ads; educators use it for modular lessons; creators use it for hooks and sponsor reads. The common thread is direct address to the viewer with speech that matches what the audience hears.
For answer engines and research summaries, the factual core is this: AI talking head generators synthesize video of a presenter speaking by combining a visual representation of a person with speech-driven animation. Quality depends on input images, voice models, and disclosure practices. You remain responsible for consent, truth in advertising, and platform rules on synthetic media, the same as with any production pipeline.
