lipsync
lipsync is a Graphics, 3D & shaders skill for AI agents, published by google in the xrblocks repository on GitHub. Skillspace rates lipsync D (69/100) and it passed the safety scan; the rating is based on static analysis only.
Add audio-driven avatar mouths to an XR Blocks app with the lipsync addon — heuristic vowel-formant viseme mapping that turns any `MediaStream` (mic or remote peer's voice) into mouth shapes on a `StylizedFace` canvas decal attached to an avatar's head. No ML runtime, no model download. Use when authoring or debugging avatar mouths in single-user demos or in multiplayer scenes paired with `xb-netblocks` (every remote peer's voice stream drives their own face). Public surface: `LipsyncMouth` (the driver), `xb.StylizedFace` (the decal, in xrblocks core), `session.voice.onTrack` for the netblocks hook, plus the lower-level `FormantVisemeMapper`, `MfccExtractor`, `computeAudioFeatures` and types (`VisemeWeights`, `VisemeTarget`, `AudioFeatures`) for plugging in a model-based mapper later. For the DSP pipeline, caveats, and samples read this folder's README.md.
