Lip Sync Guide

Make your AI characters speak with perfectly synchronized lip movements and cloned voices.

What is Lip Sync?

Lip sync takes a portrait image or video and an audio track, then generates a video where the character's mouth moves in perfect sync with the speech. Combined with voice cloning, your AI influencer can say anything in their own unique voice.

Full body talking avatar from a single image and text.

Kling Avatar Pro

High-quality talking head with subtle expressions.

MultiTalk

Step-by-Step: Create a Talking Video

1

Prepare Your Image

Use a clear, front-facing portrait. Generate one with FLUX or use an existing photo. The face should be well-lit and centered.

2

Get Your Audio

Option A: Use Text-to-Speech to generate audio from text. Option B: Upload your own audio file. Option C: Use a cloned voice.

3

Choose Your Model

Creatify Aurora for best quality, Sync Lipsync v2 for speed, OmniHuman for full body. Or use Voice-to-Video for a one-step solution.

4

Generate

Submit and wait ~1-3 minutes. The model maps audio phonemes to mouth shapes frame by frame.

5

Download & Share

Download the final video with synchronized speech. Post to social media or use in your content pipeline.

Pro Tips

Use a straight-on or slightly angled face - extreme side profiles don't sync well.
Keep audio under 60 seconds for best results.
Clone your voice first (in the Voice Clone tool) for a consistent character voice.
Use natural speech pace - very fast speech can cause artifacts.
Avoid images with hands covering the mouth or heavy accessories near the face.
Mouth should ideally be closed in the source image.
