Quick answer
An AI avatar video features a digital presenter — generated from a photo or built from scratch — that speaks your script with synchronized lip movement. Instead of filming a person, you provide an image and text (or audio), and the AI produces a talking-head video. Common uses include explainers, course content, spokesperson ads, and multilingual versions of the same message.
Avatar videos combine several AI systems: image or video generation for the presenter, text to speech for the voice, and lip-sync modeling to match mouth movement to the audio.
The appeal is speed and scale — one approved avatar can deliver hundreds of scripts without scheduling shoots, and updating a video means editing text rather than refilming.
VdoBloom’s avatar and spokesperson tools generate talking videos from a single photo, with voices from ElevenLabs, Google Gemini TTS, and xAI.
