Brazilian Portuguese speakers change ‘t’ and ‘d’ to ‘ch’ and ‘j’ respectively before ‘i’ and ‘e’ sounds. For example, the word ‘de’ meaning ‘of/from’ is pronounced more like ‘juh’.
This happened in Japanese too, where the original “ti, tya, tyo” became “chi, cha, cho”! These are all types of palatalisation, which is one of the most common types of sound change across languages.
