Background

India is home to a vast linguistic diversity, with hundreds of languages spoken across the country. Many of these languages are considered low-resource, characterized by limited digital presence, scarce linguistic datasets, and few written records. This presents significant challenges for the development of natural language processing (NLP) technologies, including machine translation (MT), speech recognition, and digital archiving. Low-resource Indian languages such as Tulu, Bodo, and Kashmiri often lack the robust parallel corpora and annotated datasets necessary for training state-of-the-art language models, impeding their integration into modern AI systems.
Tulu, for instance, is a South-Dravidian language spoken by approximately 2.5 million people, with multiple dialects and a rich cultural heritage. Despite its historical significance and similarity to sister scripts like Malayalam, which evolved from the Grantha script, Tulu suffers from limited linguistic resources. Research on its script and language, such as that by Prof. Gunda Jois, relies heavily on evidence from inscriptions and manuscripts to document its structure and evolution. These resource constraints, combined with the complexity of Indian languages—such as script diversity, grammar, code-mixing, and sociolinguistic context—make it difficult to develop effective machine learning models without significant data collection and curation efforts.
In response to these challenges, Indian startups are pioneering efforts to create AI tools tailored to low-resource languages. They often have to build datasets from scratch, employing community-driven initiatives to collect and annotate linguistic data by engaging local speakers, including women and elders, through storytelling sessions and workshops in rural areas. The use of multilingual models such as mBERT and XLM-R enables cross-lingual knowledge transfer, while multimodal approaches that integrate textual data with audio and visual inputs show promise in overcoming data scarcity. These initiatives not only advance the documentation and learning of regional languages but also foster cultural preservation and participation among creative communities.

Impact on Low-Resource Languages

Low-resource languages face significant challenges due to the scarcity of linguistic data and lack of specialized computational tools tailored to their unique structures and contexts. Unlike high-resource languages such as English and French, which benefit from decades of corpus development, many Indian languages—including Tulu—lack sufficient datasets, dictionaries, and annotated corpora necessary for effective natural language processing (NLP) applications. This shortage hampers empirical research and the development of machine learning models, limiting these languages’ integration into modern digital platforms.
Initiatives like TuluAI exemplify how startups address these challenges by leveraging large language models (LLMs) and community-driven approaches to develop resources and tools for under-represented languages. By creating extensive parallel corpora and domain-specific datasets across multiple Indian languages, such projects foster multilingual communication in vital sectors such as healthcare, education, and governance. These efforts enhance machine translation and speech recognition capabilities and facilitate the preservation of cultural identity and linguistic diversity in the digital age.
Moreover, community involvement is pivotal in this process. Collaborations with native speakers and scholars ensure that AI tool development aligns with the cultural values and needs of language communities, promoting a sense of ownership over linguistic data—referred to as “digital land” by advocates of cultural sovereignty. This participatory model helps overcome algorithmic biases and technological disparities between regions, accelerating language documentation and encouraging creative participation in language preservation.
The importance of such technologies is particularly evident in applications like offensive language identification (OLI) on digital platforms. Under-resourced languages such as Tulu, often appearing in code-mixed formats using multiple scripts, present unique challenges for content moderation and online safety.

In practical applications like offensive language identification (OLI) within code-mixed Tulu texts, ambiguity in linguistic cues poses additional difficulties. Comments may contain sarcasm, humor, or culturally specific references that make it challenging to consistently annotate and classify offensive content. Such nuances often lead to multiple valid interpretations depending on tone and context, complicating model training and evaluation in this domain.
Existing pre-trained transformer models, including mBERT and XLM-RoBERTa, have demonstrated suboptimal performance when applied to Tulu and other under-resourced languages. These limitations highlight the importance of language-specific fine-tuning and adaptation, as general multilingual models do not sufficiently capture the linguistic nuances required for effective understanding and generation. Furthermore, evaluating language models remains a difficult task due to varying experimental conditions and reproducibility issues, which can hinder fair comparisons across different approaches.
On the data curation front, maintaining a diverse and high-quality set of prompts with clear provenance is critical. Efforts to improve safety and prevent model over-refusal have involved incorporating contrastive prompts, but balancing safety with performance remains a challenge. Collectively, these issues emphasize the need for continued innovation in data collection, annotation strategies, and model development tailored specifically to low-resource languages like Tulu.

Future Prospects

The future of leveraging large language models (LLMs) to support low-resource languages, particularly in the Indian context, holds significant promise due to growing interdisciplinary collaboration and innovative technological developments.
