What is Lip Sync?
AI Lip Sync takes a still image of a face and an audio track, then generates a video where the face moves naturally to match the speech. The result looks like the person in the photo is actually talking.
Combined with Voice Clone (text-to-speech with any voice), you can create a full talking avatar from scratch: generate a face with AI, clone a voice, and produce a speaking video.
Step-by-Step
- Create a character image — Generate a portrait on the Generate page. Front-facing, clear face, good lighting works best.
- Prepare audio — Either upload your own audio file, or use Voice Clone to generate speech from text.
- Go to Lip Sync — Upload the portrait + audio.
- Generate — Wait 2-5 minutes. The AI produces a video with natural lip movements.
Use Cases
- Social media characters: Create a virtual influencer or mascot
- Presentations: AI narrator with a face
- Language learning: Characters speaking different languages
- Music videos: Characters lip-syncing to songs
Tips for Quality
- High-resolution face images produce better results
- Front-facing portraits work much better than side profiles
- Clear audio without background noise syncs more accurately
- Keep videos under 30 seconds for best quality
