WX notation

WX notation is a transliteration scheme for representing Indian languages in ASCII.

This scheme originated at IIT Kanpur for computational processing of Indian languages, and is widely used among the natural language processing (NLP) community in India.

[1] The salient features of this transliteration scheme are: Every consonant and every vowel has a single mapping into Roman.

Typically the small case letters are used for un-aspirated consonants and short vowels while the capital case letters are used for aspirated consonants and long vowels.

This scheme was further extended to represent all the Indian scripts derived from Brahmi.
