I've tried speaking danish to ChatGPT and asking it very simple questions. I even tried using complete words and pronouncing them properly (inb4 kamelåså)[1], but it didn't help. I didn't manage to have it transcribe a single sentence properly.

I believe you, but I'm surprised it doesn't do Danish. It manages Cantonese though, which I think is fairly niche (Google translate doesn't support it).
