Lip sync—synchronizing a character's mouth movements with spoken dialogue—is essential for natural, engaging animation. Without it, characters appear stiff, robotic, or disconnected from their audio tracks. Auto lip-sync tools analyze audio files, detect phonemes (distinct units of sound), and automatically generate keyframes or drive shape keys that match the mouth movements to the dialogue. This saves animators from manually creating keyframes for every syllable, allowing them to focus on performance, expression, and storytelling instead. Select your audio, either as a WAV file

Auto lip-sync tools rely on predefined mouth shapes called . For the script to work, your character must have specific Pose Library positions or Shape Keys named correctly. Required Mouth Shapes (Visemes) Most tools use the standard Rhubarb classification: A: Closed mouth (for consonants like P, B, M).

— Once captured, the lip-sync data can be applied to your character's shape keys or pose library assets, generating keyframes that align with the detected phonemes.

If you are using an add-on that relies on (a common, free, open-source engine), the installation is slightly different because you must link the plugin to the engine. 1. Download the Components Download the Blender Rhubarb Add-on .zip file.
