Lip Sync AI
What is Lip Sync AI and how does it work?
Lip Sync AI uses the Global Audio Perception technology to transform a portrait image and audio into a talking video with perfectly synchronized lips, natural facial expressions, and head movements. You upload a portrait image, provide or generate audio (via TTS), and the AI generates a lip-sync video that appears in your history.
What image and audio formats does Lip Sync AI support, and are there any limits?
Portrait formats: PNG, JPG, JPEG, WEBP.
Audio formats: MP3, WAV, OGG, M4A.
Audio duration limit: 15 seconds. A free option is available, with longer audio durations available by upgrading to a premium plan.
How do I create a lip sync video?
Steps:
- Upload your portrait image.
- Upload your audio file (or generate speech with TTS).
- Click Generate to create the lip sync video.
- Refresh to view the generated result in the History.
Where can I view my generated lip sync videos?
Generated videos are displayed in the History section. You can refresh the page to view your latest results.
Can I use Lip Sync AI videos commercially?
Yes. The site markets 100% original content with full commercial rights for generated lip-sync videos.
Is there a free option and how does it differ from premium?
Yes, there is a free option with a 15-second audio duration limit. For longer audio durations and potentially additional features, upgrading to the premium plan is required.
What makes Lip Sync AI's technology unique?
Core breakthroughs include:
- Global Audio Perception Engine that analyzes audio for natural lip-syncing, expressions, and head movements.
- Context-Enhanced Audio Learning using a Whisper-Tiny model across multiple time resolutions.
- Motion-Decoupled Controller that separately manages expression intensity and head movement based on audio.
- Time-Aware Consistency Fusion to maintain temporal consistency and reduce drift in longer videos.
What kinds of projects is Lip Sync AI suited for?
Lip Sync AI supports a wide range of creative needs, including lip sync battle content, professional presentations, multilingual training videos, and educational avatars—any project that benefits from realistic talking portraits.
Do I need animation experience to use Lip Sync AI?
No. Lip Sync AI is designed for all creators and does not require prior animation experience.
How is Lip Sync AI priced and how can I access more features?
Pricing information is available on the Pricing page. There is a free option with basic limits, and upgrading to premium unlocks longer audio durations and additional features.
