Brahmi-Net: A transliteration and script conversion system for languages of the Indian subcontinent

We present Brahmi-Net- an online system for transliteration and script conversion for all ma-jor Indian language pairs (306 pairs). The sys-tem covers 13 Indo-Aryan languages, 4 Dra-vidian languages and English. For training the transliteration systems, we mined paral-lel transliteration corpora from parallel trans-lation corpora using an unsupervised method and trained statistical transliteration systems using the mined corpora. Languages which do not have parallel corpora are supported by transliteration through a bridge language. Our script conversion system supports con-version between all Brahmi-derived scripts as well as ITRANS romanization scheme. For this, we leverage co-ordinated Unicode ranges between Indic scripts and use an extended ITRANS encoding for transliterating between English and Indic scripts. The system also pro-vides top-k transliterations and simultaneous transliteration into multiple output languages. We provide a Python as well as REST API to access these services. The API and the mined transliteration corpus are made available for research use under an open source license. 1
