Indian Sign Language Infrastructure

ISL for all,
from India

MIRA converts spoken and written language into Indian Sign Language — produced by a 3D signing avatar in real time.

Built for Deaf and Hard-of-Hearing individuals. MIRA restructures meaning into sign-friendly grammar. No cameras. No captions. No guessing.

3D signing avatar — linguistic interface

Clarity First

What MIRA Is — And Isn't

Understanding what MIRA does starts with understanding what it deliberately does not do.

MIRA does

  • ✓Convert voice or text into structured Indian Sign Language
  • ✓Restructure meaning into sign-friendly grammar — not word-for-word
  • ✓Produce signs via a 3D avatar with pre-authored, reproducible gestures
  • ✓Fall back to fingerspelling when a gesture is unavailable
  • ✓Work offline with core signing functionality

MIRA does not

  • ✕Show captions or subtitles — MIRA produces sign language itself
  • ✕Use cameras to recognize or guess gestures
  • ✕Replace human interpreters — MIRA is a tool, not a substitute
  • ✕Generate probabilistic or unpredictable motion
  • ✕Collect visual or biometric data of any kind

The Process

How MIRA Works

A deterministic pipeline. Every output is traceable from input to sign.

1

Receive Input

Voice or text is received. If voice, it is first converted to text.

2

Restructure to Gloss

Language is restructured into sign-friendly gloss — meaning over words.

3

Map to Gestures

Each gloss token maps to a pre-authored gesture. Missing signs are fingerspelled.

4

Avatar Signs

The 3D avatar performs the sign. Every motion is deterministic and reproducible.

Input→ Text→ Gloss→ Gesture→ Sign

Every output is traceable. "AI decided it" is not an acceptable explanation.

This is a demonstration. MIRA converts language into sign expressions using its core system. Results may vary.

Our Principles

Why MIRA Is Built This Way

Core Principle

Sign Language First

Spoken language is input, not authority. MIRA restructures meaning the way a Deaf signer would naturally express it — not the way a hearing person speaks.

Non-negotiable

Accuracy Is Safety

Accuracy is not a quality metric — it is a safety constraint. "Mostly right" is treated as wrong. Incorrect sign language is harmful output.

By Design

Deterministic, Not Probabilistic

MIRA does not guess. Every sign is pre-authored, encoded, reproducible, and explainable. If the system cannot explain why a sign was produced, it does not produce it.

Accountability

The Deaf Community Holds Authority

Correctness is validated by Deaf community consensus first, linguistic experts second, established corpora third. Internal opinion is last.

If the Deaf community rejects something, MIRA is wrong — even if metrics say otherwise.
