Hello everyone! Because the audio is in Nothern dialect so the letters d, gi and r will be pronounced as z in "zoo". In Southern dialect, letters d and gi will be pronounced as y in "yes". For the sound /d/ as d in "do", Vietnamese language uses the letter đ to represent it.
Yep. To my surprise, the VN team has decided to use "dơ" instead of "bẩn" even though they announced that they would use Northern dialect throughout the course. My father is from the North while my mother is from the South, so I rarely hear my father say "dơ" but "bẩn". My mother does say "dơ" all the time. Lol!
Yep, Vietnamese does have different vocabularies and pronunciations depending on regions (North, South, Central). Each region, in turn, has its own vocabularies and pronunciations. This is just like English where British accent may sound posh, American accent may sound casual while Australian one is just !@$!%#$ (no offense)
