I build voice-AI that listens to children and adults — and I run a small startup turning that research into real products. By day a professor at NIT Hamirpur; the rest of the time, a builder of careful, useful things.
Teaching, researching, building, shipping. A few numbers I am quietly proud of.
A research project that grew up. HappyVoiceLearn started as a question — can we listen carefully enough to a child's voice to help them grow? VoiceHeart is the answer scaling out, as a venture.
A 66-point developmental framework for children's speech. 6,000+ acoustic features extracted via OpenSMILE, scored against early-childhood norms — clinically validated by CMC Vellore's Developmental Paediatrics Unit.
The venture taking the same listening engine to adult psychological wellbeing — 58 markers across six domains, grounded in Logotherapy, VIA Character Strengths, ACT and Positive Psychology. Quiet, careful, clinically informed.
From tiny embedded chips to large language models — all of it is, secretly, the same craft: making machines listen carefully and respond kindly.
Unsupervised neural translation, cross-lingual embeddings, treebanks and ASR for Kangri, Kinnauri Pahari and other low-resource Indic languages. A small archive of voices, kept alive in code.
Real-time streaming with Whisper, ElevenLabs & LiveKit. 6,000+ acoustic features via OpenSMILE for child-development screening.
10+ shipped systems · Claude, GPT, Gemini, Llama · agentic workflows over n8n.
NVIDIA Jetson · object detection · depth · natural-language scene description. NVIDIA TITAN Xp grant, 2018.
SBST, BIST, ATPG, Network-on-Chip routers. Started at Sasken & Texas Instruments OMAP.
Cross-platform parental control · cyberbullying / predator detection · screen-time governance across Windows, macOS, iOS, Android, iPadOS.
Lane & road detection for hilly, unstructured, shadow-heavy roads. Driver-assist where the GPS gives up.
A research programme on low-resource Indic languages — corpora, treebanks, embeddings, ASR baselines, and end-to-end translation pipelines.
Each tag is months of corpus collection, dependency annotation, and patient translation. The marked ones are formally classified as definitively endangered.
A scattered shelf of joys. Hover any card to bring it forward.
Bilingual English/Hindi episodes for school-age learners. Foundational science, drawn out loud.
A series exploring foundational science, written for low-resource bilingual classrooms.
Students AI Plus & Educators AI Plus. People learning, in public, together.
Member of the Student Counseling Committee at NIT Hamirpur. Mostly: just being there.
2nd place, Claude Code Hackathon 2025. 3rd place, n8n automation hackathon 2025.
A series of bilingual (English/Hindi) science readers, written and illustrated to make foundational STEM feel like story-time.
Workshops, keynotes, and hands-on sessions — for educators, students, and corporate teams.
Whether it's a research collaboration, a voice-AI prototype, an AI workshop for your school or company, or just a coffee — I'd love to hear from you.
