Overview

DeafTawk set out to solve a challenge millions face every day: the communication gap between the deaf/hard-of-hearing community and the hearing world. Human interpreters, while valuable, are often unavailable, costly, or delayed — making day-to-day interactions difficult and limiting independence.

To unlock true accessibility, DeafTawk envisioned a solution that could interpret speech into sign language instantly, reliably, and without human bottlenecks.


The Challenge

Human interpreters can't scale — and that's the problem

466 million deaf and hard-of-hearing people globally lack accessible real-time communication tools. DeafTawk needed a production-grade AI interpretation engine capable of handling high video call volumes without accuracy degradation.

Real-time ASL interpretation required solving NLP, animation, and video rendering simultaneously
  • ASL has its own grammar and spatial logic — word-for-word text-to-sign translation produces incorrect signs
  • The animation library had to be curated for clinical accuracy — rough signs would undermine user trust entirely
  • Speech processing, animation mapping, and video rendering had to run in sequence with no perceptible latency
  • Privacy-safe design meant no audio or video could be retained server-side after processing

Our Solution

AI-driven sign language interpretation at scale

Built a real-time ASL interpretation engine with a curated animation library, NLP-driven speech processing pipeline, and optimised video rendering — reducing latency and communication barriers at scale. API embedded into B2B platforms.

A curated ASL animation library. Word-to-sign translation mapping. NLP-driven speech and text processing. Real-time animation synthesis. Video rendering optimized for clarity and speed.

As users speak, the system processes audio, interprets intent, and transforms text into accurate ASL animations — all within seconds. This removes reliance on human interpreters and ensures consistent access to communication support.
