A Comparative Study Of Ai-Powered Language Tools

Introduction

Artificial Intelligence (AI) is changing the way people use and understand language. Today, AI tools can correct grammar, translate languages instantly, and even understand spoken words. These tools are especially useful in countries like India, where many languages are spoken. Tamil is one of the world's oldest and most respected languages, spoken by more than 70 million people. It has a long history and rich culture. However, many global AI tools do not give enough support to Tamil. Including Tamil in AI systems is important to protect its heritage, make technology fair for all, and help people in rural and regional areas use digital tools more easily [3].

This paper looks closely at three major AI language tools – Shoonya AI, Google Bard and Bhashini – and studies how well they support the Tamil language. The goal is to understand how these tools can help in different areas like education, government work, media and communication especially for Tamil speaking users. Tamil is a language where words are built by adding different parts (like tense, gender, number, or case) to a root word. This type of structure is called agglutinative. As a result, AI tools often face challenges in breaking sentences into words (tokenization), identifying the role of each word (part-of-speech tagging), understanding sentence structure (syntactic parsing), and analysing changes in word forms (morphological analysis) [4,5].

Tamil is written as a script based on ancient Brahmi letters. It is supported by Unicode, but special care is needed for correct display and processing – especially because most AI tools are built to work with scripts like English, not Tamil. There are not enough labelled Tamil texts or open-source datasets available for training AI. Tamil has many regional dialects and ways of speaking that vary widely. Words in Tamil often change form based on grammar rules, which makes processing harder. Literary Tamil includes rich, poetic language and context-based meanings, which are difficult for machines to understand correctly.

Ai Tools: Overview and Functional Comparison

This work focuses on three AI-driven language tools — Shoonya AI, Google Bard (Gemini), and Bhashini — each was designed to enhance multilingual communication in India, with significant support for Tamil along other Indian languages. While their core objective is to reduce language barriers, each tool brings distinct technological approaches, capabilities, and user benefits.

AI4Bharat-Shoonya AI

Shoonya AI is an open-source multilingual translation platform developed by AI4Bharat at IIT Madras. It is built specifically to handle translations between English and several Indian languages, including Tamil, Hindi, Telugu, Bengali, and Kannada. Unlike generic translation engines, Shoonya leverages neural machine translation (NMT) models fine-tuned on domain-specific datasets such as government records, legal content, healthcare materials, and educational resources. This enables translations that retain contextual meaning and cultural appropriateness. The platform supports document uploads, real-time text translation, and large-scale content conversion, making it highly relevant for educators, researchers, and government services aiming to provide inclusive access to information.[11]
