: Map specific mouth shapes to phonemes (sounds) like 'A', 'E', 'O', and 'M/B/P' to ensure the character's speech looks natural.

Open the Sidebar (N-panel) in the 3D Viewport and locate the Rhubarb tab.

Shoot yourself acting out the dialogue. Watch how your own mouth moves, how your eyebrows rise and fall, and how your head tilts. Use this reference to guide your animation decisions.

In Blender, you can automate lip-syncing by using add-ons that map audio phonemes to your character's mouth poses (visemes). As of 2026, several streamlined tools are available directly through Blender's Extensions system or as specialized plugins. 1.
