@Dušan All the words he said correctly were pronounced like a real Slovak would. It would be easier to spot a Czech trying to speak Slovak. Plus I’ve watched a few videos with spelling of the Serbian alphabet. All letters sounded exactly like I imagined in my Slovak brain.
Yea, when I was in Croatia, I’ve noticed the difference in stress or intonation or whatever it is between Slovak and Croatian. It’s closer to eastern Slovak than to standard in my opinion.
