Indic-trans: Cross-Language Transliteration Tool

Indic-trans provides a state-of-the-art transliteration module for cross-transliterations (representing multilingual languages in English) among Indian languages, including English and Urdu.

Key Features

1. Rule-Based and Machine Learning Models:

   • Option to choose between rule-based (default) or machine learning-based transliteration.
