# KlingLipSyncTextToVideoNode - ComfyUI Built-in Node Documentation

> Kling Lip Sync Text to Video Node synchronizes mouth movements in a video file to match a text prompt.

Kling Lip Sync Text to Video Node synchronizes mouth movements in a video file to match a text prompt. It takes an input video and generates a new video where the character's lip movements are aligned with the provided text.
