What makes Serbian hard for speech recognition
Serbian is written in both Cyrillic and Latin, so transcripts need one fixed convention. It has pitch accent and vowel length that spelling doesn't show, and it's close enough to Croatian and Bosnian that a model needs native Serbian data to get the differences right.

- Automatic speech recognition (ASR / STT)
