These smart glasses promise to turn your silent mouth movements into text

Subvocal, a Y Combinator-backed startup founded by Georgia Tech computer science students, has developed working prototypes of smart glasses that translate subvocal communication—silent mouth movements—into written text. The glasses use low-powered radio waves that detect distortions caused by facial muscle movements and lip shape changes. The company has published preorder pricing at $499 for an early-bird launch expected in Q1 2027, with final pricing still to be announced.
