Nedávalo mi to smysl, rozhodně to nebylo fér.
Measured on 20 FLEURS clips, 2026-09-05. That figure is for Czech spoken on its own; accuracy on mixed speech is measured separately and not claimed here. Full method, all 59 languages
Borrowed words are declined
Czech puts English nouns through its case system, and the ending is part of the word as spoken. It is written that way.
Diacritics are part of the word
č, ř, ž, ě and the rest are transcribed rather than stripped to plain Latin letters.
Timing measured, not estimated
Word-level alignment against the audio itself.
Czenglish — two languages in one sentence
Czech takes an English word, gives it a case ending and treats it as native. A transcriber that recognises the English root and writes the clean English word has removed the grammar that made the sentence work — and the result reads as slightly wrong in a way that is hard to point at.
