Adi Vaani: India’s First AI Translator for Tribal Languages -

In August 2025, India’s Ministry of Tribal Affairs launched Adi Vaani, the country’s first AI-powered translator for tribal languages. This pioneering initiative marks a turning point in India’s efforts to preserve linguistic diversity while ensuring that technology reaches even the most remote communities. The app is currently available in beta on the Google Play Store, with iOS and web versions expected soon. For millions of tribal citizens who have long struggled with barriers in communication, Adi Vaani promises to be both a practical tool and a cultural lifeline.

A Collaborative Effort Rooted in Community

The journey of Adi Vaani is a remarkable story of collaboration. The project brought together some of India’s leading academic institutions IIT Delhi, BITS Pilani, IIIT Hyderabad, and IIIT Naya Raipur alongside Tribal Research Institutes from states such as Jharkhand, Odisha, Madhya Pradesh, Chhattisgarh, and Meghalaya. Unlike many top-down digital initiatives, Adi Vaani relied heavily on contributions from tribal communities themselves. Local teachers, storytellers, and cultural leaders were involved in curating language datasets, translating folk tales, oral histories, and educational content. This ensured that the AI was trained not just on textbook material but on the lived culture and identity of the people it seeks to serve.

Technology at Its Core

Adi Vaani uses sophisticated frameworks such as No Language Left Behind (NLLB) and IndicTrans2, which are specifically designed to work with languages that have limited digital resources. The app is not limited to text; it integrates a variety of modes including text-to-text, text-to-speech, speech-to-text, and speech-to-speech translations. This makes it versatile enough to be used in classrooms, healthcare centres, or even at community gatherings. Another important feature is Optical Character Recognition (OCR), which can digitize old manuscripts and inscriptions, ensuring tribal literature and songs can be archived for future generations. A growing set of bilingual dictionaries and learning primers further enhances its role as both a translator and an educational companion.

Languages in Focus: Launch Phase and Expansion

At launch, Adi Vaani supports Santali, Bhili, Mundari, and Gondi languages spoken by millions across central and eastern India. Each of these languages carries centuries of oral traditions, folk songs, and indigenous knowledge. Future updates are expected to include Kui from Odisha and Garo from the Northeast, with more tribal tongues to follow. The vision is to eventually cover all major tribal languages of India, ensuring no community is left behind in the digital age.

Serving Society: Beyond Translation

While Adi Vaani is a linguistic innovation, its true strength lies in its potential social impact. For instance, healthcare workers in tribal regions can use the app to communicate vital health advisories, particularly about challenges such as sickle cell disease, which disproportionately affects tribal populations. Similarly, teachers can use it to make NCERT and state curriculum content accessible in students’ mother tongues, improving educational outcomes. Government schemes and welfare initiatives can also be translated in real time, reducing the information gap that often prevents tribal citizens from accessing entitlements. Even Prime Minister’s speeches and official announcements can be subtitled in tribal languages, symbolically placing tribal voices at the heart of national conversations.

Preserving Heritage and Promoting Inclusion

Language is not only a medium of communication but also a repository of culture. Tribal communities often rely on oral traditions, which are vulnerable to being lost with each passing generation. By offering tools for documentation and digitization, Adi Vaani provides a modern platform to record folk tales, proverbs, songs, and rituals. This digital archive will be invaluable not only for the communities themselves but also for researchers, educators, and cultural historians. Importantly, the app fosters a sense of pride among young tribal learners, showing them that their mother tongue is not just relevant but part of India’s digital future.

Part of a National Mission

Adi Vaani is closely aligned with broader government missions such as Digital India, Ek Bharat Shreshtha Bharat, Adi Karmayogi Abhiyan, Janjatiya Gram Utkarsh Abhiyan, and PM JANMAN. By integrating with these programs, the app goes beyond being a technological experiment it becomes a vehicle for inclusive governance. For a country as linguistically diverse as India, this project symbolizes a commitment to ensuring development is equitable and culturally sensitive.

The Road Ahead

Looking forward, Adi Vaani faces both opportunities and challenges. Expanding coverage to more languages will require deeper collaboration with communities, as well as continuous refinement of AI models to improve accuracy. Ensuring accessibility in regions with poor internet connectivity will be crucial, possibly through offline features. Equally important is sustained engagement with tribal youth, encouraging them to use the app not just as consumers but as contributors who help refine translations and preserve cultural narratives.

Conclusion

Adi Vaani is more than a translator it is a bridge between tradition and technology, between marginalized voices and mainstream governance. By combining advanced AI with grassroots participation, the initiative demonstrates how innovation can serve both modern communication needs and cultural preservation. As the app matures and its language coverage expands, it holds the promise of not only connecting people across linguistic barriers but also ensuring that India’s tribal voices continue to resonate for generations to come.
