A startup named Subvocal has announced the development of smart glasses that offer an innovative solution to the problem of text input in wearable devices. The technology relies on converting silent mouth movements into accurate written text, eliminating the need for virtual keyboards or traditional voice dictation.
How does the technology work?
Subvocal glasses rely on radio signal-based sensing technology, inspired by research from the AlterEgo project at the MIT Media Lab. Instead of using cameras or intrusive electrodes, the glasses transmit radio signals toward the mouth area, where these signals are modulated based on the movement of muscles and the tongue during silent speech. The system then analyzes these changes and converts them into understandable words.
What distinguishes this innovation?
The true strength of this technology lies in its ability to work without the need to open the mouth or produce any audible sound, providing high privacy for the user in public places. Unlike current input technologies that rely on touch or cumbersome air gestures, these glasses provide an invisible and fast input interface.
Availability and future prospects
The company has opened pre-orders for the device at a price of $199, with expectations that the final price upon launch will reach $499. Shipping is scheduled to begin in the first quarter of 2027. Although the prototype appears with a rough technical design, the company emphasizes that the system requires minimal calibration for new users.
What does this mean for users?
This technology represents a qualitative leap in how we interact with wearable devices, transforming glasses from mere display screens into integrated input tools. If the technology proves its efficiency in daily use and the required speed, it may open the door to a new generation of devices that rely on "silent speech," reducing the gap between the speed of thought and the speed of typing on mobile devices.
