Subvocal raised $1.3M. A developer recreated it with AirPods in 9 minutes
Summary
Subvox is a macOS prototype that investigates turning AirPods Pro head-motion data into text without using a language model. It employs a small-vocabulary template recognizer and a statistical test, with a full build/run and experiment protocol, illustrating a hardware-assisted approach to motion-based speech recognition and its evaluation.
