Subvox: one-prompt, 9-minute rebuild of silent-speech recognition using AirPods Pro motion data

seatedro · x · 2026-10-31

joeblau recreated "subvocal" in 9 minutes with a single prompt, open-sourced as Subvox — a macOS prototype testing whether AirPods Pro head-motion data (CMHeadphoneMotionManager) carries enough signal to turn silently mouthed words into text. No language model: just a small-vocabulary template recognizer plus a statistical test. Repo includes full xcodegen/Xcode build steps (macOS 14+). As seatedro quipped: it's always "recreated," never "created" — AI now makes recreating demos nearly free.
