@kangkengkhadev @S2P2 Can you help this issue?

I just had an idea: if we parse the word to obtain its pronunciation (คำอ่าน) first (maybe by using pythainlp.transliterate.pronunciate), it might be easier to determine the correct marttra (มาตรา). However, I have not tested this yet, so I am unsure if it will work.
