The Indic languages include Hindi, Urdu, Bengali, Sanskrit, and several other languages. These languages are the dominant language family of the Indian subcontinent. The number of people that speak an Indic language is upwards of 900,000,000.
The master plan involves generating independent finite-state transducers for each language, and then making individual dictionaries and transfer rules for every pair. The current status of these goals is listed below.
Status
The ultimate goal is to have multi-purposable transducers for a variety of Indic languages. These can then be paired for X→Y translation with the addition of a CG for language X and transfer rules / dictionary for the pair X→Y. Below is listed development progress for each language's transducers and dictionary pairs.
Transducers
Once a transducer has ~80% coverage on a range of medium-large corpora we can say it is "working". Over 90% and it can be considered to be "production".
