Sounds that change the spelling
Ten minutes with the two places pronunciation actually changes Serbian spelling: a voiced consonant that meets a voiceless one across a morpheme boundary gets written the way it sounds (натпис), while a normally voiced consonant at the end of a word keeps its letter no matter what (град). Meet two familiar words again, hear натпис said aloud, and build the difference into muscle memory.

Play it, say it out loud, then move on. Nothing is recorded and nothing is scored here — graded pronunciation is the speaking step.
