Translate Video to Czech

What to expect when translating into Czech

Czech grammar has seven cases and rich word endings, so the translation sometimes picks the wrong ending for names or gendered nouns. The meaning usually survives, but proofread anything customer-facing.

The Czech voice track

Czech stresses the first syllable of words, so foreign brand names may come out with Czech-style stress in the voice.

Voice, MP4, subtitles and transcripts: 350 credits (35¢). Subtitles and transcripts only: 7 credits (0.7¢).

Czech subtitles

Czech subtitles keep č, ř, ů and ě intact in UTF-8 files; older desktop players set to a legacy code page may show garbled letters until switched to UTF-8.

Czech (Čeština) is written in the Latin alphabet with diacritics.

Switch Full translation output off for subtitles only: 14 credits (1.4¢). If the video is already in Czech, select Czech as the language instead and the subtitles come back untranslated — see Czech transcription.

Translating audio files into Czech

Podcasts and recordings go through the audio translator, which returns a Czech M4A and transcripts: 1,250 credits ($1.25) with voice, 25 credits (2.5¢) as text only.

Who translates into Czech

Czech is spoken in the Czech Republic. It's used by manufacturers and software companies with Czech teams, Czech universities, and creators reaching Czech viewers.

Vykání or tykání

Czech has a formal vy (vykání) and an informal ty (tykání), and English "you" gives the translation no clue which one you want. Companies, public institutions, customer support and most training use vykání. Some youth brands, gaming channels and community videos use tykání. The difference shows in every imperative: "klikněte" and "podívejte se" are formal or plural, "klikni" and "podívej se" are informal.

Machine translation chooses sentence by sentence, so check the translated subtitles for both kinds of imperative and settle on one. Remember that vykání also covers a group of viewers, which makes it the safer default when a presenter is talking to a room.

Names in the vocative and other case traps

Czech uses a separate case when addressing someone directly. Petr becomes Petře, Jana becomes Jano, and pan Novák becomes pane Nováku. When a presenter says "Thanks, Peter", the Czech line should read "Díky, Petře"; machine translation sometimes leaves the name in its dictionary form. Search the subtitles for every greeting and every name used in direct address.

Foreign names decline too: "s Johnem", "od Sarah" or "od Sary" depending on house style. Czech traditionally adds -ová to women's surnames, including foreign ones, and whether to write Merkelová or Merkel is an editorial choice to make once and apply everywhere. Translating names and technical terms suggests keeping a short list for each project.

Numbers, units and line breaks

• Decimal comma and a space between thousands: 1 250,50 Kč.
• Dates written with spaces after the dots: 1. 10. 2026.
• Ordinals take a dot: 3. kapitola means chapter three.
• Quotation marks open low and close high: „takto“.
• One-letter prepositions and conjunctions (v, k, s, z, o, u, a, i) should not end a line. When you edit the SRT, move them to the start of the next line with the word they belong to.

That last rule is a Czech typographic convention that most subtitle editors don't enforce, so it is worth a dedicated pass over the file before publishing.

Technical vocabulary needs a decision too. Czech developers and gamers say "commitnout", "deploy" or "levelovat", while official documents prefer Czech terms. Machine translation can produce either, sometimes within one video, so choose per term based on who will watch and check the subtitles against that choice.

Preview the Czech dub before committing

In dub mode, the Czech translation is read by one of the 8 stock voices and placed against the original timing. There is no lip-sync and no separate voice per speaker, and some lines may be shortened to fit. Czech is supported for dubbing like every other language in the picker, but how a voice treats Czech stress, names and numbers is something to hear for yourself rather than assume. Listen before you dub a long video.

On the result screen, play the preview at 0.75× and at normal speed with the original and translated text side by side. Check how names, numerals and abbreviations are read out, whether any line is rushed, and whether the voice you picked suits the speaker. The AI dubbing quality checklist lists what else to listen for, and AI voice mispronounces names covers fixes for problem words.

Czech television has a long dubbing tradition, while online viewers are used to subtitles as well, so neither format is automatically right. A low-risk order is to publish Czech subtitles first and add a dub only after a Czech speaker has heard the preview.
