Read full description

Adi Vaani is a cutting-edge translation platform and app designed to bridge communication gaps and preserve India’s tribal languages. Developed under the Ministry of Tribal Affairs, this AI-powered tool enables users to translate text and speech between Hindi, English, and key tribal languages, with support for additional languages under development. The app uses advanced machine translation, speech recognition, and optical character recognition (OCR) technologies to offer: • Text-to-text translation between Hindi, English, and tribal languages such as Santali, Bhili, Mundari, and Gondi (with more languages to be added). • Speech-to-text and speech-to-speech translation to support natural verbal communication across communities. • OCR translation, allowing users to extract and translate text from images and documents. Beyond translation, Adi Vaani aims to digitize and safeguard tribal cultural heritage, provide bilingual dictionaries, provide interactive learning support, and make vital information—including government advisories and health awareness materials—accessible in native languages. This app supports inclusive communication, aids education and public service access, and plays a key role in preserving endangered tribal languages for future generations.
