The SamaVaad Infinity Loop
Closing the conversational gap through continuous hardware and AI integration.
Direction 1: Deaf → Hearing
The glove captures ISL signs, an on-device AI model converts them into a grammatically correct sentence in the hearing person's regional language, and it's spoken aloud.
Direction 2: Hearing → Deaf
The hearing person speaks naturally, the AI transcribes and restructures it into ISL grammar, and an animated avatar signs the response back.
Step-by-Step Workflow

The Six AI Layers
The proprietary architecture powering true bidirectional fluency.
ISL Gesture Recognition
A temporal CNN/LSTM model on-device classifies flex-sensor and motion data into ISL signs in real time, adapting to each signer's style.
Cross-Linguistic Grammar Bridge
True bidirectional fluency requires a Cross-Linguistic Grammar Bridge, not mere word-swapping. Indian Sign Language has a fundamentally different grammar from spoken languages (lacks articles, tense markers, uses strict topic-comment order). Our Seq2Seq Transformer AI Engine strips tense markers and restructures syntax rules in real-time to ensure total fluency in both directions.
Regional Language Text-to-Speech
Converts the reconstructed sentence into natural speech in the target Indian language, with voice models cached on-device for offline use.
Speech Recognition + NLP Simplification
Transcribes the hearing person's speech and restructures it into clean ISL-compatible grammar, removing articles and tense markers.
ISL Avatar Animation Engine
Renders the sign sequence as a smooth animated avatar using motion interpolation between signs, rather than robotic pre-recorded clips.
Federated Personalization & Context
The model fine-tunes to each user's signing style on-device (federated learning, no personal data leaves) and uses recent conversation context to resolve ambiguous signs.
