Cartoon Lip Sync: Put the Words in Your Character’s Mouth
Upload a cartoon character, type what it says, and an AI video model makes the voice and the mouth together, so every word lands on the lips. 2D, 3D, anime and clay characters all work, and there are no mouth shapes to draw, no timing to set and no audio to line up by hand.
- Mouth in sync with the voice
- 2D, 3D and anime
- Two-character dialogue
- 4–30 second takes
- No watermark

Cartoon lip sync examples
Turn the sound on and watch the mouths: fast words, a pause, a song. The red panda says one line and sings another with the same face; the crocodile speaks Hindi, translated under the clip. Just want a character to say hello? Make a talking cartoon
An anime girl, tears then anger
“Senpai didn't notice me, but maybe the real senpai was the friends we made along the way. No, I'm still mad. I'm so mad.”
A 3D presenter
“Hey, besties, just wanted to share this amazing tool I found: AI lip sync.”
A red panda that talks…
“I started as one drawing. Now I can talk, tell a story and welcome viewers without filming a single frame. The same character can even sing when you switch the audio.”
…and the same panda singing
The same picture with a song instead of speech: the mouth follows the melody.
A crocodile rant, in Hindi
“Hey humans, you are something else. You look at us like a crocodile sent you a tax bill. At least we crocodiles live in the water; you spend all day drowning in your phones. So who is the real crocodile?”
Lines that show off the lip sync
Fast words, a whisper, a shout, a rap and two dialogues. Tap a card to drop it into the box above, then make it your own.
A tongue twister
“She sells seashells by the seashore, and the shells she sells are surely seashells. Wait, what?”
A whispered secret
“Psst. Come closer. Don't tell anyone, but the cookies are hidden behind the flour.”
A big shout
“Three, two, one… it's the weekend! Let's goooo!”
A short rap
“I wake up early, I brush my fur, I rule this street, yes I do, for sure!”
Two characters argue
Left: “Who ate my sandwich?” Right: “What sandwich? I don’t see any sandwich.”
A tiny interview
Left: “So, what is your secret talent?” Right: “I can, um… I can whistle with my nose.”
How to lip sync a cartoon character
- 1
Add the character
Upload a clear picture with the face and mouth in view. It becomes the first frame, so the character and the style stay exactly as drawn.
- 2
Write the words and the voice
Put the line in quotes and describe how it is said: fast, whispered, shouted, sung. For two characters, give each line to “the one on the left” or “the one on the right”.
- 3
Generate the take
The model makes the voice and the mouth in one pass. H3 Max Turbo renders a 5-second take for 63 credits at 480p; generate again for a different take.
Lip sync animation, without drawing mouth shapes
In hand-made lip sync animation, an animator draws a set of mouth shapes, one for each family of sounds, and swaps them frame by frame to match a recorded line. It is careful, slow work, and it is why cartoon dialogue takes so long to animate.
An AI video model does it differently: it makes the voice and the moving picture together, so the mouth is shaped around the words as they are spoken, along with the blinks, the eyebrows and the head moves that sell a line. There is no audio track to line up afterwards.
Cartoon lip sync also differs from real-person lip sync. Cartoon mouths are simpler and more exaggerated, and a good take opens wide on the big sounds and snaps shut on the pauses. Ask for that in the prompt (“big, bouncy cartoon mouth movements”), and keep the style named so the model does not turn your character into a realistic face.
Which model lip syncs your cartoon best?
Every model below renders the voice and the mouth in the same pass, from the line you type. They differ in length, picture quality and price, and H3 Max and Seedance 2.5 can also take a voice recording. Switch between them in the box at the top.
| Model | Starts from | Length | Up to | Credits (smallest size) | Good for |
|---|---|---|---|---|---|
| H3 Max Turbo | Your picture as the first frame | 5–15s | 1080p | 63 for 5s | The cheapest way to test a line and the timing. |
| Vidu Q3 Turbo | Your picture as the first frame | 4–15s | 1080p | 88 for 5s | Quick dialogue takes with sound effects. |
| H3 Max | Your picture as the first frame | 5–15s | 1080p | 125 for 5s | Takes a voice recording as a reference in Reference mode. |
| Vidu Q3 | Your picture as the first frame | 4–15s | 1080p | 175 for 5s | Holds a character from up to four reference pictures. |
| Seedance 2.5 | Your picture as the first frame | 5–30s | 1080p | 238 for 5s | Longest single take, the most natural motion, takes a voice recording. |
| Kling 3.0 | Your picture as the first frame | 4–15s | 1080p | 250 for 5s | Voices with sound effects and ambience, at 720p and 1080p. |
| ToonBee 1.0 | Reference pictures of your characters | 15s and up | 720p | 1,341 for 15s | A finished cut: several shots with dialogue, narration and music. |
Prices are for the smallest size each model offers; larger sizes cost more, and every model charges by the second. The cheapest test is H3 Max Turbo: 63 credits for 5 seconds.
Two characters talking, or a whole episode
Two characters in one picture can trade lines in a single take: give each line to “the one on the left” or “the one on the right”. The model does not always get the speaker right, so for a real back-and-forth make one take per line, each with the speaker in front, and cut them together. The characters stay the same because every take starts from your picture.
For a scene with several shots, ToonBee 1.0 writes the shot list, cuts between shots and lays down the dialogue with lip sync, narration and music, from 15 seconds with no set ceiling. For a narrated cartoon of several minutes, the AI cartoon video generator draws every scene and reads the story with one narrator voice; the lip-synced lines are made here and cut in.
Tips for cleaner cartoon lip sync
- Pick a picture with the mouth closed or slightly open and clearly visible; a mouth already wide open leaves less room to move.
- Front views sync best. Side views and tiny faces in a wide scene give the model less mouth to work with.
- Write the line the way it is said: commas for pauses, “…” for a trail-off, capitals for a shout.
- Ask for cartoon mouths: “big, bouncy cartoon mouth movements, lips closing on every pause”.
- About ten to twelve words fit a five-second take; give longer lines a longer take rather than squeezing them in.
- For two speakers, say who talks first, and keep each line short.
Where cartoon lip sync helps

Mascots and ads
A brand character delivering a slogan with the timing of a real voice actor.
Comedy sketches
Two characters arguing, a dramatic villain, a rant to the camera.

Pricing
Every plan runs the same AI cartoon video generator and the same AI models — you are only choosing how many scenes a month you need. Credits are charged per scene and shown before you render.
Good to know before you start
- This makes a new clip from a picture. It does not re-sync the mouth of a cartoon video you already have to new audio.
- A take runs 4–30 seconds depending on the model, so long speeches are made one line at a time.
- Only H3 Max and Seedance 2.5 take a recording, and as a guide: the mouth may drift from it. Typing the line gives the tightest sync.
- The mouth is generated, not traced from a chart, so now and then a take is off. Generate again for another take.
- The models run with content filters that turn away some prompts and pictures, such as well-known characters. A refused generation gives its credits back.
Cartoon lip sync FAQ
What is cartoon lip sync?
Cartoon lip sync means making a cartoon character’s mouth move in time with the words it speaks. Here an AI video model does it from one picture and a typed line, making the voice and the mouth movement together.
How are cartoons lip synced?
By hand, an animator draws a set of mouth shapes, one for each family of sounds, and swaps them frame by frame to match a recorded line. With AI, a video model makes the voice and the moving mouth together from one picture and the typed line, so there is nothing to time by hand.
How do I lip sync a cartoon character with AI?
Upload a clear picture of the character, type the line in quotes, describe the voice and generate. You get a clip where the character says the line with its mouth on the words, ready to download.
Can I upload my own audio for lip sync?
On H3 Max and Seedance 2.5, yes: add the recording in Reference mode and point to it in the prompt. The model takes it as a guide, so the mouth may not match it word for word. Typing the line gives the closest sync.
Can it lip sync an existing cartoon video?
No. It makes a new clip from a picture of the character. To redub a cartoon you already have, start from a still of the character and make the new line as a new take.
Does lip sync work for anime and 3D characters?
Yes. Flat 2D, anime, 3D, clay and mascot characters all lip sync, as long as the face and mouth are visible. Name the style in the prompt so it is kept.
Can two cartoon characters have a lip-synced conversation?
Yes. Put both in the picture and give each line to “the one on the left” or “the one on the right”. For longer dialogue, one take per line is the most reliable, cut together afterwards.
How is cartoon lip sync different from real-person lip sync?
Cartoon mouths are simpler and more exaggerated: they open wide on big sounds and close on pauses. Real-person lip sync aims at small, realistic lip shapes. Ask for cartoon mouth movements in the prompt to get the cartoon kind.
Is there free cartoon lip sync?
Signing up is free and comes with 100 credits, which covers a 5-second take on H3 Max Turbo (63 credits). After that, takes use paid credits; a one-time pack is $49. There is no watermark on downloads.
How long can a lip-synced take be?
4 to 30 seconds per take, depending on the model. ToonBee 1.0 makes longer cuts with several shots, from 15 seconds. Longer speeches are made one line at a time.
What languages can the character lip sync in?
Write the line in the language you want and name the language in the prompt. The models are strongest in English; for other languages, try a short take first.
Put the words in your character’s mouth
Upload a cartoon, type the line, and watch the lips land on every word.
