Giving Voice
to Sign Language
EchoVerse AI translates sign language to speech and speech to sign in real-time using a smooth, expressive 3D avatar — bridging 466M+ deaf and hard-of-hearing people with the world.
The Communication Gap is Real
466 million people are deaf or hard-of-hearing. Current tools are slow, robotic, or require human interpreters.
Slow & Expensive
Interpreters cost $50-150/hr. Not scalable for daily chats.
Robotic Avatars
Existing avatars are uncanny, lack emotion and smooth signing.
No Privacy
Cloud-only solutions can't be used in hospitals or schools.
EchoVerse AI
A real-time, on-device AI that speaks sign language.
- ✓Smooth 3D Avatar — 60fps hand & face rig, not pre-recorded clips
- ✓Two-way — Sign → Speech and Speech → Sign instantly
- ✓Private & Offline — runs in browser with WebGPU
Watch our avatar sign smoothly, not robotically

Fluid motion blending
Face + hands synced
No loading screens
How It Works
MediaPipe Hands tracks 21 points at 60fps
