These muscle-reading wearables let you use voice input without speaking a word

TL;DR Subvocal’s glasses tech uses radar to analyze the movement of muscles in your mouth. From those readings, it can extrapolate the words you’re saying — even if you’re just silently mouthing them. Pre-orders for the wearable are open now, with orders expected to ship in Q1 2027. Ever since mobile devices started getting smaller than a laptop, engineers have been tackling the difficult question of how we’re supposed to enter text. We’ve gone from tiny physical keyboards , to touchscreen keyboards, to gesture-based glide typing . On wearables, the situation’s even trickier, and it can feel like we’re stuck either using voice input or left awkwardly poking in the air at a virtual keyboard. But now one startup has a clever, hands-free solution that works silently. How many of you speak aloud to yourself as you type? Or maybe when proofreading, do you ever silently mouth the words as you’re reading them? You might be a prime candidate for trying out Subvocal’s glasses tech, which translates silent mouth movements into written text (via Hacker News ).
