It  is  a  strategic  initiative  to  establish  a  robust  and  inclusive  Al  ecosystem  aligned  with  India's development goals through the seven pillars -IndiaAI Compute, AIKosh, IndiaAI Foundation Models, IndiaAI FutureSkiIIs, Startup Financing, Application Development and Safe & Trusted Al.

Around 275 datasets have been uploaded on AIKosh. This includes 100+ Tamil language datasets contributed by leading organisations.

The IndiaAI Mission supports the creation and funding of Indian-language Al datasets for various use cases including NLP, speech, translation and content moderation.

## Mission BHASHINI:

Mission BHASHINI under the Digital India Programme enables multilingual digital access by developing Al-powered  speech  and text  technologies  for  Indian  languages.  It  functions  as  the official repository under the National Language Translation Mission (NLTM).

BHASHINI has been  developed  through  a  national  collaboration  of  over  70  research  partner institutes. It hosts a repository of over 350 AI-based language models and offers 22+ specialized language services. It offers Automatic Speech Recognition (ASR), Machine Translation (MT), Text-to-Speech (TTS), Optical Character Recognition (OCR), and Transliteration.

·

## Dataset corpus includes:

- Ø  246 million parallel sentence pairs
- Ø  3.7 million monolingual text entries
- Ø  14,000 hours of ASR audio
- Ø  2.5 million OCR image samples
- Ø  476 hours of TTS audio
- Ø  20.56 million transliteration entries across Indic languages

All datasets and models are publicly accessible via the BHASHINI platform or through the Digital India BHASHINI Division account on the AIKosh platform.

Dedicated datasets for Indian languages including Tamil and spoken variants have been created. For ASR, transcribed speech datasets and trained models are available for 22 scheduled Indian languages, including Tamil, contributed by A14Bharat at IIT Madras.

The Tamil datasets include parallel and monolingual corpora, ASR (labelled/unlabelled), TTS, OCR, transliteration, terminology, NER (Named Entity Recognition) and  glossary resources, publicly accessible through the BHASHINI and AIKosh platforms.

Development work has been carried out with linguistic experts, research and academic partners, through structured consultation.

A total fund of INR 47 crore was allocated for building datasets for 22 scheduled Indian languages across  Translation,  Speech  Recognition,  Speech  Synthesis  and  OCR  activities,  and  the  entire amount has been fully utilised.
