Sign Bridge

Sign to your camera. Bridge says it out loud.

Gestures to voice and text. Sign Bridge watches your hands through the webcam, recognises signs you’ve taught it — in any sign language — and speaks them, with live captions so you can check what was said. Keep it in a small window next to a video call.

What it does

  • Teach your own signs: show each one 3 times, in any sign language
  • Quick gestures that work straight away (hello, yes, no, I have a question…)
  • Speak each sign, or build a sentence and let AI make it natural
  • Captions and a history of everything Bridge said for you

How it works

  1. MediaPipe finds 21 points on each hand in every camera frame — on your device
  2. Bridge compares the movement with the signs you taught it (dynamic time warping)
  3. The matching words are spoken with your chosen voice; only words, never video, go to the AI step
