See it in action
Built for scenes full of characters
- ✓Per-character timeline & words — every mouth keeps its own recognized text. Click a character and instantly see that character's transcript and color strips on the timeline.
- ✓One-click full Clear — removes a character's keyframes, words, timeline text and audio in one go, with a confirmation that names the character. One Undo restores everything.
- ✓Active-character indicator — the panel always shows which character Generate and Clear will affect.
- ✓Link the mouth to any rig bone — defaults to "Mouth", or type your own (e.g. "Mond"), so the whole mouth follows head rotation.
- ✓Unified "BlenderGem" sidebar tab — neatly grouped with the rest of the BlenderGem 2D toolset.
Hours of keyframing, reduced to seconds
Manually lip-syncing a 30-second dialogue takes hours. Frame-by-frame layer toggling, second-guessing phoneme timing, redoing it all when the script changes.
2D Lip Sync Pro reads your audio, detects phonemes with offline speech recognition, and generates clean keyframes on your Grease Pencil mouth layers — automatically. Point it at a WAV or MP3, click Generate, keep working.

Speak 5 Languages
Offline speech recognition powered by Vosk. No cloud, no API keys, no recurring fees — your audio stays on your machine.
English works out of the box. The other languages download their speech model with one click from the Setup panel. G2P fallback gives unknown words automatic phoneme guessing for NL, DE, FR, ES.
Built for real animation work
Speech recognition that works offline
Powered by Vosk, CMU Pronouncing Dictionary, and Sphinx phoneme dictionaries. No cloud, no API keys, no recurring fees.
Two viseme sets, one honest workflow
Use the 7-viseme Simple set for cartoon work, or the 12-viseme Disney-style set for expressive character animation. Layer names auto-match with fuzzy detection, or link your own layers by hand.
Per-character dialogue, sorted
Each character keeps its own audio, recognized words and timeline text — and its audio lands on its own VSE channel automatically. Switch character, see that character's sync. Perfect for dialogue scenes.
Fine-tune anything
Fix a misheard word and regenerate without re-running analysis, or nudge everything with the global frame offset. Get the sync exactly right.
Modern Blender, done right
Built for Blender 5.0+ with full Grease Pencil v3 support. Installs through the Extensions Platform — no manual dependency setup.

Why I built this
I'm a working animator. For years I was stuck between two workflows — After Effects with Character Animator was powerful for lip sync but sluggish for everything else, while Blender's Grease Pencil was fast and expressive but had no real auto lip-sync option.
I kept thinking: this gap shouldn't exist. Grease Pencil deserves a proper lip-sync tool. So I built one.
2D Lip Sync Pro is the add-on I wanted for my own projects — and it keeps getting better, based on what real users, animators shipping real work, tell me they need.
Built on trusted open-source tools
No cloud APIs. No subscription fees. Everything runs locally in your Blender installation.
