ViaSign Overview
ViaSign by Viathorne Labs is an early project exploring how AI can support sign language accessibility, beginning with Singapore Sign Language.
The project is still in development. It should be understood as exploratory, review-first, and open to future community guidance.
Current Public Boundary
The public viasign-parser, reviewed only against its documented engineering contract, currently exposes safety contracts, closed natural-English surface categories, and visible uncertainty. It does not implement or publish SgSL grammar, translation, sign plans, motion, or avatar signing.
The website contains a fail-closed tester interface, but its controls remain disabled. A separate owner-approved FastAPI service was last verified in maintenance mode with empty CORS; its live provider state must be rechecked before activation. This production website remains unconfigured and does not send visitor submissions. Source publication and inert infrastructure do not make the parser linguistically authoritative or ready for public sentence submission.
Purpose
ViaSign exists because accessibility should not stop at captions, transcripts, or text-only tools.
For many Deaf people, access can also mean being able to understand, learn, and communicate through signed language.
Signed languages are full languages. They carry grammar, expression, space, movement, timing, culture, and identity.
Because of that, sign language accessibility cannot be treated as a simple word-to-gesture problem.
Direction
ViaSign may be explored in layers after each earlier boundary is ready for review:
- Understanding sentence structure
- Identifying grammar patterns
- Marking where human review is needed
- Preparing motion-ready information
- Supporting future signing output
- Involving Deaf community feedback and review
The goal is not to rush toward a polished demo.
The goal is to build carefully, layer by layer.
What ViaSign Is Not
ViaSign is not intended to replace Deaf people, teachers, interpreters, or community knowledge.
It is not intended to claim authority over Singapore Sign Language.
It is not intended to treat AI output as automatically correct.
What ViaSign Hopes to Support
ViaSign hopes to support:
- sign language accessibility
- learning and explanation
- communication access
- grammar exploration
- review and auditing
- public awareness of signed languages
- future AI-assisted accessibility tools
Building Principle
The guiding principle is simple:
Build carefully.
Respect the language.
Include the community.
Support access.
Keep the human part at the center.
ViaSign is still early, but the direction is clear: AI should support people, not replace them.
