UIDAI deploys Udai, a browser lip-synced virtual mascot answering Aadhaar questions in 11 languages

UIDAI, the body that administers India's Aadhaar identity system, has deployed Udai, an AI-powered virtual mascot that answers Aadhaar questions in conversation. Built by Daffodil Software and showcased at Aadhaar Samvaad 2026 in Kolkata on 29 September, Udai covers enrolment, address updates, fees and documents, eKYC and Virtual ID, linking Aadhaar to bank accounts, PAN and mobile numbers, mAadhaar and grievance redressal. The release says it speaks and understands 11 languages — Hindi, Tamil, Bengali, Telugu, Kannada, Malayalam, Marathi, Gujarati, Punjabi, Odia and English — replies in the language it was addressed in, and handles questions mixing English and Hindi. The character is built from pre-recorded footage with lip movements synced to speech in real time using lightweight processing that runs in a web browser, at 24 frames per second on ordinary servers without specialised graphics hardware. Answers are limited to a curated UIDAI knowledge base, with off-topic questions steered back to Aadhaar and an abuse-screening layer covering English, Hindi and Hinglish. Phase one places Udai in Aadhaar Centres; phase two puts it on the Aadhaar website and mobile app, replacing the existing text-based chatbot, which Daffodil also built. The release does not name the underlying AI or speech models.

Why it matters for digital humans: This is a useful counter-example to the generative-video default. Rather than synthesising frames, Udai lip-syncs pre-recorded footage client-side — which caps visual range but makes cost and latency predictable at population scale and keeps the character on-brand by construction. The deliberate narrowness is the other lesson: a closed knowledge base, a refusal to leave topic, and prompt-injection and impersonation safeguards, on a deployment where a wrong answer about identity documents has real consequences. The frame-rate, language and hardware figures come from the vendor's press release and have not been independently measured.
