Lip sync for animators and creators
Traditional cartoon lip sync means breaking dialogue into mouth shapes and drawing or posing each one. Lip Sync skips that: it reads the audio and animates the character for you, with the mouth on the words and the head and expression following the tone. It runs ByteDance's OmniHuman 2.0 model through BytePlus (KreatorFlow is an official partner of BytePlus, a ByteDance company).
It is built for a talking shot: one character, one take, the dialogue you recorded. That makes it a fit for explainer characters, mascots, comic panels and animated shorts where you already have the design and the voice.
How to lip sync a cartoon in three steps
- 1
Export one frame of your character
A clean image of the character facing the viewer, with the mouth visible: a drawing, a 3D render, a mascot or a frame from your own animation. Saved characters and your generations can be picked straight from the library.
- 2
Add the dialogue
Upload the voice track (MP3 or WAV, 4 seconds to 5 minutes), or type the line and pick a voice. Record the character's real voice actor if you have one; the mouth follows exactly what the audio says.
- 3
Generate the talking shot
Add an optional direction for gestures and camera, choose 720p or 1080p, and press Generate. 4 credits per second at 720p, shown before you start.
Tips for cartoon characters
- Draw or pick a neutral, slightly open mouth. A closed smile line gives the model less to work with than a mouth that is clearly a mouth.
- Face forward or three-quarter. A character seen from the side, or very small in a wide scene, lip syncs less cleanly.
- Simple backgrounds help. A flat or soft background keeps the attention on the face and keeps the style steady over a long take.
- Ask for the style to stay. In the direction, say the design, colours and line work stay unchanged, and keep camera moves small.
- Cast the voice first. The character's personality comes from the audio. Record a clean take with little background noise before you generate.
- Split long scenes. For a dialogue between characters, make one shot per line and edit them together, like a real animated show.
What creators use it for
- A brand mascot that presents your product or this week's news
- Explainer and tutorial videos with a cartoon host
- Motion comic panels where the character speaks the line
- Animated shorts and sketches for social channels
- A character that sings a song you wrote
- Pitching a character idea with its real voice before a full production

Need a character first?
Design one
Make a cartoon or 3D character from a description with the AI character generator, then save it to reuse in every video.
Use your own art
Upload a drawing, a render or a frame from your animation. Characters you created are yours to use.
Go bigger
For a full cartoon with scenes and a script from one idea, use the AI cartoon maker, then add talking shots with Lip Sync.
Start with the AI character generator or the AI cartoon maker.
Consent and responsible use
Lip Sync makes the person in a photo say whatever the audio says, so it comes with clear rules. On the website you confirm, the first time you generate with a new photo, that you are that person or have their permission. Photos are screened before anything is charged, and photos with nudity or of minors are refused.
- Use a photo of yourself, or of someone who has given you permission to make them speak. A character you created, an animal or a drawing is fine.
- Use a voice you have the right to use: your own, one of our voices, a voice you cloned with consent, or a recording you have permission for. The same goes for any music or song.
- No sexual content, nothing involving anyone under 18, and no impersonation: never make a real person appear to say something they did not say in order to mislead, harass or defraud.
- No celebrities, politicians or other public figures unless they have given you permission and you hold the rights for that use.
- When you post a talking video of a real person, say that it is AI-generated. Many platforms require that label.
Read the full rules in the Acceptable Use Policy on real people's faces and the Terms.
Cartoon lip sync questions
How do I lip sync a cartoon character?
Upload one image of the character to KreatorFlow Lip Sync, add the voice track, and press Generate. OmniHuman 2.0 animates the mouth to the dialogue and moves the head and face with the delivery, so you do not have to draw mouth shapes frame by frame.
Does it work with 2D, 3D and mascot characters?
Yes. Flat 2D cartoons, 3D characters, mascots, comic-style art and creatures all work, as long as the character has a clear face with a mouth. Characters with no visible mouth, or a mouth hidden behind a mask, do not lip sync well.
Will the character keep its design?
The video starts from your image, so colours, outfit and proportions come from it. To keep the style steady, add a direction such as "Keep the character design, colours and background unchanged" and avoid big camera moves in long takes.
Can I lip sync an existing cartoon video?
No. Lip Sync starts from a still image, not a video. To give a character in your own animation new dialogue, export a clean frame of the character and make the talking shot from that.
Can I use a well-known cartoon character?
Only if you have the rights. Characters from studios and brands are owned by someone, and fan videos with them can infringe those rights. Characters you designed, or made with our AI character generator, are the safe choice.
How much does cartoon lip sync cost?
4 credits per second at 720p and 6 at 1080p. A 30-second scene costs 120 credits at 720p. Lip Sync needs a paid plan (from $15 for the first month on Creator) or a credit pack (from $8).
Can two cartoon characters talk to each other?
One generation follows one voice track. For a conversation, make one talking shot per line (or per character) and cut them together in an editor. If both characters are in one image, say in the direction which one speaks.
Lip Sync or the AI cartoon maker?
Use Lip Sync when you already have the character and the exact audio and want that character to say it. Use the AI cartoon maker when you want a whole cartoon, with several scenes, written and made from one idea.
Make your character talk
Add one image of your character and the dialogue, and see the price before you generate. Available on any paid plan or credit pack.
