# 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.

Note: `speech` is a dynamic input that selects the speech source. When set to `"script"`, `text` and `voice` are required, and `custom_voice_id` and `voice_speed` are optional. When set to `"audio"`, `audio` is required instead.
