Abstract
Despite recent advances in developing language technologies for the standard Persian dialect, the official Iranian language, a large number of Iranian language variations remained computationally unexplored. Iranian languages, e.g., Kurdi, Azeri, and many Persian dialects are examples of low-resource language distinctions lacking significant linguistic resources such as machine-readable lexicons or part-of-speech (POS) taggers. Efforts in developing language technologies for such languages can significantly contribute to language survival in the digital era and promote cultural diversity. To the best of our knowledge, for the first time, we created linguistic resources for the Luri and the Yazdi dialects by introducing the first parallel corpora between these language variations and the modern Persian language. In this study, we train neural encoder-decoders (1) recurrent sequence-to-sequence and (2) transformer-based machine translation models and evaluate the trained model using BLEU score on an unseen test dataset.
