Finite-state Transducers (FST) can be very efficient to implement inter-dialectal transliteration. We illustrate this on the Hindi and Urdu language pair. FSTs can also be used for translation between surface-close languages. We introduce UIT (universal intermediate transcription) for the same pair on the basis of their common phonetic repository in such a way that it can be extended to other languages like Arabic, Chinese, English, French, etc. We describe a transliteration model based on FST and UIT, and evaluate it on Hindi and Urdu corpora.
