## Key points

- Subvocal is building glasses that turn mouthed words into text.
- The prototype reportedly decodes speech at over 200 words per minute.
- Preorders cost $199 upfront, with a Q1 2027 release planned.

## Summary

Subvocal, a startup founded by two Georgia Tech computer science students, is developing smart glasses that convert silent mouth movements into text. The idea is to let people dictate messages, code and commands to computers without speaking aloud, potentially offering a quieter alternative to voice input and keyboards.

The prototype uses low-powered radio waves to detect changes in facial muscles and shape as the wearer mouths words, then translates those signals into text. The founders say it can decode speech at more than 200 words per minute, but have not provided an accuracy rate or details such as battery life. A preorder costs $199 upfront, with a further $300 due when the glasses ship; the company lists a planned Q1 2027 release.
