2D Lip Sync Pro automates lip sync for Grease Pencil in Blender, reading WAV or MP3 audio, detecting phonemes with offline speech recognition, and generating keyframes on mouth layers across five languages.

PencilRig is a Blender add-on that automatically links Grease Pencil layers to Armature bones. Name your layers and bones identically, and PencilRig connects them from a dedicated panel with one-click linking and unlinking.
