How to lip sync cartoon mouth via viseme

A viseme is the visual representation of a phoneme, which is the smallest unit of sound in speech. Based on that knowledge, viseme-based syncing in Reallusion offers precise control over every mouth shape and movement, making it a powerful tool for creating realistic, frame-accurate cartoon mouth lip sync animation. In Reallusion tools like iClone and Character Creator, viseme-based syncing is used to match animated mouth shapes to specific phonemes from spoken audio.

Steps to create cartoon animation lip sync with Reallusion

STEP 1
1. Select a character

Start with any fully rigged Reallusion character, in the Reallusion Character Creator (CC) to design your 3D character. You can customize facial features, body proportions, clothing, and more. Once the character is ready, use the "Send to iClone" feature to export it seamlessly.

STEP 2
1. Add voice over in iClone

In iClone, go to "Animation" and select "Create Script", then choose "AccuLips". This allows you to type in your script in the text box, or import your audio file (WAV/MP3) or record a voiceover directly in iClone. The software will use AccuLips, Reallusion's advanced lip-sync engine, to analyze the text or speech and generate viseme keyframes that match phonetic sounds with appropriate mouth shapes.

STEP 3
1. Save

Then, open the "Timeline" and expand the viseme and expression tracks. Use the AccuLips editor to review and refine the phoneme-to-viseme alignment. You can drag, adjust, or replace viseme keys for more accurate lip sync, and enhance realism by adding eye movement, eyebrow motion, and head nods in the expression track. When you are done, click on the "Save" icon to save it to your computer.

2. Viseme timeline: This is a powerful tool designed for refining lip-sync accuracy. Visemes represent the visual mouth shapes that correspond to specific phonemes (speech sounds), and this timeline allows you to adjust them frame-by-frame. By fine-tuning each viseme, you can align mouth movements precisely with the audio track, making your character’s dialogue look fluid, expressive, and natural.

3. Lip sync chart: This built-in visual reference serves as a guide for matching mouth shapes to specific phonetic sounds during speech. It provides a clear breakdown of common visemes, which are the visual counterparts to phonemes, so animators can accurately align character mouth movements with dialogue. By using the chart, creators can manually adjust each frame to refine automated lip-syncing or build custom animations from scratch.

How to make cartoon lip syncing via timeline

Timeline-based cartoon mouths for lip syncing in Animaker use facial tracking to guide lip movement in animated characters.

Instead of analyzing the entire audio waveform in detail, Animaker focuses on key visual frames to create a believable lip-sync effect. This method allows users to animate talking characters quickly without getting into complex timing adjustments.
