| > **Welcome to CIIL’s official home on Hugging Face, where India’s many languages help shape what AI can become.** |

|
|
| For more than five decades, the **Central Institute of Indian Languages (CIIL)** has advanced language research, education and preservation. This Hub extends that work into collaborative AI research, with a focus on models, datasets and resources that help people learn, create and participate through their own languages. |
|
|
| ## Linguistic knowledge as a foundation for AI |
|
|
| Our work connects linguistic research with practical resources: |
|
|
| - **Linguistic Data Consortium for Indian Languages (LDC-IL):**<br /> |
| Text, speech and lexical resources, including annotated corpora and benchmarks, for Indian language research and technology. |
| - **National Translation Mission (NTM):**<br /> |
| Knowledge translation across the 22 Scheduled languages, supported by glossaries, terminology resources and translator training. |
| - **Bharatavani:**<br /> |
| Dictionaries, educational content and multilingual knowledge in a digital repository spanning more than 100 languages and dialects. |
| - **Scheme for Protection and Preservation of Endangered Languages (SPPEL):**<br /> |
| Documentation and revitalization of endangered languages through oral traditions, grammars and vocabularies. |
| - **National Testing Service–India (NTS-I):**<br /> |
| Research, assessment frameworks and educator training to strengthen language teaching, learning and evaluation. |
|
|
| ## Research directions on the Hub |
|
|
| - **Speech:**<br /> |
| Recognition, synthesis and language identification across accents, regional varieties and multilingual speech. |
| - **Translation:**<br /> |
| Resources that help knowledge move between Indian languages and widen access to education and services. |
| - **NLP and generative AI:**<br /> |
| Models and datasets attentive to linguistic structure, cultural context and code-mixing. |
| - **Scripts and documents:**<br /> |
| OCR, transliteration and document understanding to make written knowledge searchable and usable. |
| - **Data and evaluation:**<br /> |
| Curated resources and transparent benchmarks that reveal performance across languages, domains and speaker communities. |
|
|
| These are our research directions. Each repository explains what is available. |
|
|
| ## A digital future with room for every language |
|
|
| A language can hold centuries of knowledge yet remain scarcely represented in AI. We prioritize low-resource, tribal and endangered languages alongside India’s Scheduled languages and wider diversity of mother tongues. |
|
|
| Speakers, educators and linguists help guide resources that reflect how people communicate, so more communities can access learning, research and digital services. |
|
|
| ## Collaborate with care |
|
|
| We welcome researchers, developers, educators and language communities. Explore the resources, share findings and contribute, with care for consent, attribution, cultural context and data provenance. |
|
|
| Check each repository for language coverage, intended uses, evaluation, limitations and licensing. |
|
|
| **Help shape an AI future in which people can learn, create and participate through their own languages.** |
