Muscle Reading Wearables

Startup Subvocal opens pre-orders for radar-based silent-speech glasses

Subvocal has begun taking pre-orders for a wearable that uses radio signals, rather than cameras or electrodes, to detect mouth and tongue muscle movement and convert silently mouthed words into text. The company says shipments are expected to begin in Q1 2027. The approach draws on prior research from MIT Media Lab's AlterEgo project, which used electrodes instead of radar.
