Speech Datasets and Models for Tibeto-Burman Languages of India

Dataset created under the Speech Datasets and Models for Tibeto-Burman Languages (SpeeD-TB), sponsored under Mission Bhashini by Ministry of Electronics and Information Technology (MEITY), Govt of India. The project aimed to create 1,200 hours of speech dataset and ASR models for 6 underresourced, tribal Tibeto-Burman languages of India speoken in Eastern and North-Eastern parts of India.

Prof. Bornini Lahiri

Chief Investigator and Consortium Leader · Indian Institute of Technology Kharagpur

I have special interest in the features of minor and endangered languages of India. I have been involved in documenting and describing various minor languages of West Bengal since last six years. Some of them are Dhimal, Mahali, Toto, Kurmali etc. I have helped in building corpus and creating digital dictionaries for some of these languages. I am interested in developing tools for the minor languages of India as these languages are often less-resourced and hence lesser used than the major languages of the country which adds to the vulnerability of the language. I also study ethno-linguistic features of the languages which bring out amazing facts about languages and the related cultures. Studying contact induced languages in the languages is also one of my research areas. The contact induced changes become more fascinating for me when the languages belong to different language families. Like, one of my studies explores the effect of Indo-Aryan language on a minor Tibeto-Burman language.

I have some works on applied linguistics where I have tried to locate the problems of second language learning. One of such studies reports, an investigation of English spelling errors by the students of native Hindi speakers. English spelling error is a very common problem of our country where Hindi is a major language and most of the school education is done through English medium. Many interesting facts are revealed in the study.

I am also interested in typology. I explored noun cases of seven Eastern Indo-Aryan (EIA) languages for my Ph.D. It was an intra-genetic work based on primary data. Cognitive Framework was used to describe the cases. Cases in EIA languages show dense polysemous network, which has been justified in the study.

Dr. Ritesh Kumar

Chief Investigator and Consortium Leader (Former) · Unreal Tece LLP / Council for Diversity and Innovation (Earlier: Dr. Bhimrao Ambedkar University)

Ritesh is a linguist whose research intersects pragmatics, sociolinguistics, and AI systems for social good. He computationally models politeness, impoliteness, and language aggression, and develops safety benchmarks evaluating the harm potential and cultural appropriateness of LLM responses. He has built language resources and technologies for minoritised and endangered languages like Awadhi, Beda, Braj Bhasha, Magahi, Toto, and Chokri, alongside supporting tools like the LiFE Suite for humanities and social sciences research. Currently, he is serving as the CEO of the AI startup Unreal Tece LLP, focusing on data and models for the last million. Additionally, he is the co-founder and director of the Council for Diversity and Innovation, a non-profit Section 8 company that trains indigenous communities and works with stakeholders on linguistic and cultural documentation, digitisation, lexicon development, grammar writing, and language technologies.
