Glossary
A video format where a single person (or avatar) talks directly to camera — the dominant format for tutorials, sales outreach, course modules, and social explainers.
Talking-head videos win on conversion because the viewer sees a face, hears a voice, and builds trust faster than with screen-only content. The format is short enough to ship daily and dense enough to carry real information.
AI talking-head generators remove the bottleneck of recording, re-recording, lighting, and editing — you can ship the same script in five languages, by five different presenters, in an hour.
A digital character — usually built from a single photo — whose lips, jaw, and expressions are animated by AI to match a chosen voice or script.
A virtual on-camera spokesperson generated by AI — used for explainer videos, product demos, courses, and internal communications.
A tool that produces finished video files from inputs such as text prompts, scripts, photos, or audio — without filming. Talking-avatar generators are one of the most practical sub-categories.
