The Thai Romanization dataset contains 648,241 Thai words \
that were transliterated into English, making Thai \
pronounciation easier for non-native Thai speakers. \
This is a valuable dataset for Thai language learners \
and researchers working on Thai language processing task. \
Each word in the Thai Romanization dataset is paired with \
its English phonetic representation, enabling accurate \
pronunciation guidance. This facilitates the learning and \
practice of Thai pronunciation for individuals who may not \
be familiar with the Thai script. The dataset aids in improving \
the accessibility and usability of Thai language resources, \
supporting applications such as speech recognition, text-to-speech \
synthesis, and machine translation. It enables the development of \
Thai language tools that can benefit Thai learners, tourists, \
and those interested in Thai culture and language.
