AI4Bharat: How India Is Using Artificial Intelligence to Break Language Barriers

Artificial Intelligence (AI) is transforming the way people learn, communicate, work, and access information. However, in a country like India, where people speak hundreds of languages and dialects, one major challenge remains: making AI accessible to everyone, regardless of the language they speak.

This is where AI4Bharat plays an important role. Associated with the Indian Institute of Technology Madras (IIT Madras), AI4Bharat is a research initiative focused on developing AI technologies for Indian languages. Its mission is to make digital technology more inclusive by helping people interact with computers in languages they understand.

What Is AI4Bharat?

AI4Bharat is an Indian AI research initiative that focuses on building language technologies for India's diverse linguistic landscape. Its research includes machine translation, speech recognition, natural language processing, and other technologies that help computers understand and process Indian languages.

Many digital services are designed primarily around English. This can create difficulties for people who are more comfortable speaking Hindi, Tamil, Bengali, Telugu, Marathi, or other Indian languages.

AI4Bharat works to reduce this gap by developing language models, datasets, and tools that researchers and developers can use to build better AI-powered applications.

When Was AI4Bharat Started?

AI4Bharat began in 2019, with a focus on advancing AI research for Indian languages.

An important milestone followed on July 28, 2022, when the Nilekani Centre at AI4Bharat was officially launched. The centre received ₹36 crore in funding support from Nandan Nilekani and Rohini Nilekani to advance research and development in Indian-language technology.

It is important to distinguish between the two milestones: AI4Bharat started in 2019, while the Nilekani Centre at AI4Bharat was officially launched in 2022.

Who Founded AI4Bharat?

AI4Bharat was established by researchers associated with IIT Madras. Two prominent researchers connected with the initiative are Dr. Mitesh Khapra and Dr. Pratyush Kumar.

Their work focuses on developing AI systems that can understand, process, and generate language beyond English. By supporting research into Indian languages, AI4Bharat contributes to the development of technology that reflects India's linguistic diversity.

How Does AI4Bharat Work?

AI4Bharat develops language technologies using approaches such as Machine Learning, Deep Learning, and Natural Language Processing (NLP).

These technologies allow computers to perform tasks such as translating text, recognizing spoken words, processing written language, and converting words between different writing systems.

For example, a developer could use an Indian-language translation model to build an application that translates educational material from English into Hindi. Similarly, speech-recognition technology can help turn spoken language into text, making digital services more accessible to people who prefer speaking rather than typing.

AI4Bharat also supports the wider research community by developing datasets and models that can be used to create new language-based applications.

Major AI Models and Projects by AI4Bharat

AI4Bharat has contributed to several projects designed to improve AI capabilities for Indian languages.

1. IndicTrans2

IndicTrans2 is a machine translation model designed to translate between English and a wide range of Indian languages, as well as support translation between Indian languages.

It can help developers build translation applications for education, communication, content localization, and other language-related tasks.

2. IndicBERT

IndicBERT is a language model designed for natural language understanding across Indian languages. It can be used in research and applications involving text classification, language understanding, and related NLP tasks.

3. IndicBART

IndicBART is a multilingual sequence-to-sequence model designed for text-processing tasks, including certain text-generation and summarization applications.

It provides researchers and developers with a foundation for experimenting with language-processing solutions.

4. IndicXlit

IndicXlit focuses on transliteration, which involves representing words from one writing system in another.

For example, it can help convert a Hindi word written in Devanagari into its representation using the Roman alphabet. This can be useful for search tools, messaging applications, and multilingual interfaces.

These projects demonstrate how specialized language models can help developers create more useful AI applications for India's linguistic needs.

Where Can AI4Bharat Technology Be Used?

AI4Bharat's research can support applications across several important sectors.

1. Education

AI-powered translation and language tools can help students access educational material in their preferred languages. This may make digital learning resources easier to understand for students who are less comfortable with English.

2. Healthcare

Language technology can support multilingual health-information services and communication tools. This may help people access information in a language they understand, although medical decisions still require appropriate professional judgment.

3. Government Services

Translation and speech technologies can help public-service platforms provide information in multiple Indian languages, making digital services more accessible to a wider population.

4. Business and Customer Support

Businesses can use Indian-language AI technologies to develop multilingual chatbots, customer-support tools, and automated communication systems.

5. Rural and Regional Communities

Voice-based applications and local-language interfaces can make technology easier to use for people who face language or literacy barriers when interacting with digital platforms.

6. Startups and Software Development

Developers and startups can explore AI4Bharat's models and research resources to create language-learning applications, translation tools, speech interfaces, and other AI-based products.

The actual benefits depend on the quality of the application, the language being supported, and the specific model used.

Why Is AI4Bharat Important for India's Future?

India's linguistic diversity is one of its greatest strengths, but it also creates challenges for digital communication. AI systems that work well in English may not perform equally well in every Indian language.

AI4Bharat addresses this challenge by supporting research into Indian-language datasets, models, and tools.

Its work could contribute to several long-term developments:

• More inclusive education: Students may gain better access to learning resources in regional languages.

• Improved digital accessibility: People may find it easier to interact with digital services through their preferred languages.

• New business opportunities: Startups can build products for regional markets that are underserved by existing language technologies.

• Better multilingual communication: Translation and speech tools can help people communicate across language barriers.

• Stronger AI research in India: Open research resources can help researchers and developers experiment with new ideas and build upon existing work.

These are potential benefits rather than guaranteed outcomes. Continued research, testing, and responsible deployment will be important for achieving them.

How Can Developers and Students Explore AI4Bharat?

Students, programmers, and AI enthusiasts can explore AI4Bharat's research projects and documentation through its official website.

A beginner can start by learning the basics of Python, Machine Learning, and Natural Language Processing. After that, they can explore available Indian-language models and experiment with simple projects, such as a text translator or a multilingual text-processing application.

Developers should check each model's documentation, license, supported languages, and hardware requirements before using it in a project.
