About Czech transcription

Czech (Čeština) is written in the Latin alphabet and spoken principally in Czechia. Subtitles generated here come back in that script, as ordinary written Czech, ready to use in an SRT or VTT file.

Czech permits syllables built entirely from consonants, so a run of letters with no vowel in it is usually correct rather than a dropped character. The everyday spoken register differs from the written standard in its endings, and transcription follows what was said rather than correcting it upward.

What a Czech subtitle file looks like

Four lines as they come out of the exported SRT, in the Latin alphabet with the timings taken from the speech itself.

1
00:00:01,000 --> 00:00:03,240
Děkuji všem, že jste přišli.

2
00:00:03,600 --> 00:00:06,120
Slyšíte mě dobře?

3
00:00:06,480 --> 00:00:09,300
Za chvíli se podělím o podrobnosti.

4
00:00:09,700 --> 00:00:12,040
Uvidíme se příště.

Czech diacritics are not optional

The marks above and below Czech letters change which word it is, not merely how it sounds. Stripping them — which some older subtitle tooling still does on upload — produces text that is wrong rather than plain.

Open an exported file once to confirm they survived before you trust a workflow with a batch. When they do not, the cause is almost always an encoding setting.

Searching a Czech transcript

Czech is heavily inflected, so a term appears in a range of forms rather than repeating identically the way an English transcript would. That is correct output.

It does mean searching a transcript for a keyword will miss most of its occurrences unless you search for the stem — worth knowing before you use a transcript as an index.

Getting a better Czech transcript

• Set the language to Czech rather than leaving detection on, particularly for clips under a minute where there is little audio to judge from.
• Upload the highest-quality audio you have; compression artefacts cost more accuracy than most people expect.
• Check proper nouns, place names and numbers first — recognition errors concentrate there.
• Read the transcript before exporting. Czech subtitles are editable up until you download them.

Czech subtitles in another language

The same Czech audio can produce subtitles in any of the 76 supported languages instead of in Czech itself. English is the most common target, but every pair works, and the translated file keeps the original timings so it drops onto the same video unchanged.
