Subvocal Launches Radar Glasses for Silent Speech-to-Text Input
Startup Subvocal has launched smart glasses using non-contact radar sensing to decode silent mouth movements into text at over 200 words per minute. This technology addresses privacy and noise issues inherent in voice dictation by tracking internal speech muscles without requiring audible sound or physical typing. The product is currently available for pre-order following a $1.3M funding round.

I did not think this was possible yet. your face just became a keyboard.
Typing with no keyboard and no voice now exists, I’m still processing this launch.
Subvocal's glasses turn silently mouthed words into text at 200+ words per minute.
Voice dictation beats typing for speed, but it becomes unusable wherever talking aloud would disturb others or expose private text.
Now that problem is solved.
Underneath, radar travels from the frames through your face, each silently formed word changes how it reflects, and the AI decodes that into text at 200+ words per minute. The people around you see, at most, a little movement at your mouth.

Typing is slow. Talking into your computer is awkward. Subvocal fixes both
Our glasses give you the speed of speech without you making a sound or touching a keyboard.
