A Comprehensive Dialect Conversion Approach from Chittagonian to Standard Bangla

We present a comprehensive conversion system to convert the Chittagonian dialect to standard Bangla language. It is a text to text conversion system based on word-to-word mapping adopting a bilingual dictionary, rule-based morphological transformation on suffixes, and a supportive word suggestion module. The system tokenizes the regional input text and processes the tokens through word-to-word mapping and morphological transformation using suffix transformation rules if word-to-word mapping fails. We are also introducing an aiding tool that generates suggested words for the dialectal input. The system achieved an accuracy of 94.75% for producing standard Bangla translation from Chittagonian words. It must be noted that there is no published work on the Chittagonian dialect conversion from a computational point of view. We are the first ones to have built such a system for Chittagonian dialect to standard Bangla conversion.
