# HeyGenTalkingPhotoNode - ComfyUI Built-in Node Documentation

> Animate a still image of a person into a lip-synced talking video using HeyGen's Avatar IV technology.

Animate a still image of a person into a lip-synced talking video using HeyGen's Avatar IV technology. You can drive the animation with a text script that HeyGen converts to speech, or provide your own audio for the avatar to lip-sync.
