Generate Czech subtitles for your Polish videos

Czech diacritics are part of the word

Czech uses marks above and below its letters that change which word it is rather than only how it sounds. Stripping them, as some older subtitle tooling and a few upload pipelines still do, produces text that is wrong rather than merely plain.

Open the exported file once and confirm the marks survived before you rely on a workflow. If they did not, the problem is almost always an encoding setting rather than the Czech text itself.

How Polish audio becomes Czech subtitles

Audio in Polish (Polski) is transcribed first, then translated into Czech (Čeština). Because the translation runs on the transcript rather than on the audio, the Czech subtitle file keeps the timings of the original Polish speech — each line appears at the moment it was actually said.

Searching a Polish transcript

Polish is heavily inflected, so the same term appears in a range of forms rather than repeating identically. That is correct output, but it means searching the transcript for a keyword will miss most of its occurrences unless you search for the stem.

It matters here because the Czech translation collapses much of that variation, and the two files will not line up term for term even though they line up line for line.

Why translate Polish video into Czech

Polish is spoken principally in Poland; Czech in Czechia. A Czech subtitle track is what lets one recording reach both audiences without re-recording, re-editing or dubbing it.

Because subtitles are a separate file rather than part of the picture, you can attach several language tracks to the same video and let viewers pick.

About the Polish audio

Polish carries two full series of sibilants that sound close to an untrained ear — the ś/ź/ć group against sz/ż/cz — and confusing them is where most transcription errors land. It also writes nasal vowels as ą and ę, and permits consonant clusters long enough that a correct transcript can look like a typing error.

About the Czech subtitles

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 Polish to Czech subtitle file looks like

Four lines of Polish speech, transcribed and translated, as they come out of the exported SRT. The timings are the Polish speaker's — translation does not move them, which is why the file drops onto the original video unchanged.

1
00:00:01,000 --> 00:00:03,240
Dobré ráno všem.

2
00:00:03,600 --> 00:00:06,120
Za chvíli se podělím o podrobnosti.

3
00:00:06,480 --> 00:00:09,300
To je pro dnešek vše.

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

What to check before publishing

• Names and places, which translation handles less reliably than ordinary prose.
• Idiom — a phrase that is natural in Polish may need loosening to read well in Czech.
• That Czech diacritics survived the export — they change the word, not just its pronunciation.
• Timing on fast exchanges, where two speakers overlap.
