# InfiniteTalk

> Audio-driven video generation that creates talking or singing videos from a single image.

InfiniteTalk is an audio-driven video generation model that creates talking or singing videos from a single image and audio input. It animates faces and bodies to match the audio, making it ideal for creating talking head videos, virtual presenters, or lip-synced content.
