GoKawiilStartup 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.
GoKawiil's interpretation of the reporting above, not reported fact.
A working silent-speech input method could sidestep the long-standing problem of text entry on small wearables, offering an alternative to voice commands or virtual keyboards that doesn't require speaking aloud in public. If reliable, this kind of tech could reshape how people interact privately with smart glasses and other hands-free devices, though its real-world accuracy and comfort remain unproven until units ship.
- Subvocal's glasses use radar-like radio signals to read mouth muscle movement, not cameras or electrodes.
- The tech can transcribe words a user silently mouths without speaking aloud.
- Pre-orders are open now, with shipping expected in Q1 2027.
