Lip Sync Feature

Kling AI has introduced a powerful lip sync feature that allows you to seamlessly match speech to a character’s lips. Whether you’re working with AI-generated videos, animated characters, or real photos, this tool makes it easy to create realistic, synchronized dialogue.

In this guide, we’ll cover:
✅ How to use the lip sync feature
✅ Best practices for achieving realistic results
✅ Limitations and workarounds

How to Use Kling AI Lip Sync Feature

1️⃣ Log into Kling AI & Open the AI Video Interface

  • Navigate to the AI video generation tool.
  • Choose or generate a base video where the AI will apply lip sync.

2️⃣ Upload a Photo or Video for Lip Syncing

  • The easiest videos to sync with are close-up shots where the character’s lips are clearly visible.
  • If using an AI-generated video, enter a prompt like:
    📌 “A person is speaking directly to the camera.”
  • Click Generate to create the base video.

3️⃣ Apply Lip Sync to Your Video

  • Click on the “Match Mouth Type” button.
  • The AI will analyze the video to determine if lip syncing will work.
  • Once the analysis is complete, upload your audio file containing the voiceover.

✅ If the audio file is longer than the video, you’ll get an option to crop it to fit the duration.
✅ Click the “Lip Sync” button, and the AI will process the video.
✅ The process typically takes 5–10 minutes.

Text-to-Speech & Custom Voices

🎙️ Want to generate speech without uploading an audio file? Kling AI allows you to:

✅ Type the exact dialogue you want the character to say.
✅ Choose from different AI-generated voices to match the tone and style.
✅ Adjust the speech rate to make it sound more natural.

This means you don’t need a pre-recorded voiceover—just type what you want, and Kling AI will generate the speech and sync it to the character’s lips!

4️⃣ Review & Redub (Optional)

  • If the results aren’t perfect, use the Redub button to upload a new audio file and try again.
  • The AI will reprocess the lip sync, allowing for adjustments.

Lip Sync in Different Animation Styles

💡 Does Lip Sync Work for All Video Styles?
Yes, but with some limitations:

🎭 Photo-realistic & 3D videos → Best results with crisp, natural-looking speech.
🎨 Anime-style & 2D animations → Lips sync less accurately, may appear choppy.

📌 For the best results in animated videos:

  • Use prompts like “subtle motion” or “static camera” to minimize head movement.
  • Keep characters’ heads still to improve sync accuracy.

Lip Sync with Multiple Characters

If your video has multiple people, Kling AI will automatically choose one face to sync. However:
❌ There’s no way to manually select which character gets dubbed.
✅ The feature works well for action shots, even if there’s background movement.

Text-to-Speech & Custom Voices

🎙️ Want to generate speech directly in Kling AI? You can:

  • Upload a video and type the exact dialogue for the character.
  • Choose from different AI-generated voices.
  • Adjust the speech rate for a more natural sound.

Free Version & Queue Time

If you’re using Kling AI’s free version, you may experience a queue before processing begins. However, considering the quality and convenience of built-in lip sync, it’s worth trying!
