About Slovak subtitling

Where a Slovak line can be broken, and where it cannot

Slovak lets r and l carry a syllable on their own, with no vowel in sight. Vlk is a wolf, prst is a finger, štvrť is a quarter, and each of those is one syllable built around a consonant. Written long, as ŕ and ĺ, they are always syllabic: vŕ-ba and vĺ-ča are two syllables apiece. Anything that finds syllables by hunting for vowels gets Slovak wrong on the first line it touches.

That matters because making a subtitle fit comes down to two moves, breaking the line somewhere legal or shortening the words, and Slovak narrows both of them. A rhythmic rule stops a long syllable from following another long syllable inside the same word, and ŕ and ĺ are counted as long. So the shorter ending that would have saved you two characters can be the one the language will not allow after that particular stem.

Our Slovak subtitlers are native speakers who read a line the way a viewer meets it rather than the way a character counter tallies it. Breaks land on genuine syllable boundaries, condensing leaves the rhythmic rule intact, and the file gets played back before it ships instead of being signed off inside the editing grid.

Which do you need?

Open captions, closed captions or SDH

Three different deliverables that people often ask for by the wrong name. Here is the short version.

Open captions

Burnt in

Subtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for social feeds that autoplay muted — and in Slovak it fixes the line breaks in the image, so no player can re-wrap them somewhere the language forbids.

  • Always visible
  • Line breaks fixed in the image
  • Delivered as a finished video file

Closed captions

Switchable

A separate file the viewer can turn on and off, and that can carry several languages at once. The standard for YouTube, Vimeo and the streaming platforms.

  • Viewer controls them
  • Multiple languages from one video
  • Indexed by search engines

SDH

Accessibility

Subtitling for the deaf and hard of hearing: dialogue plus speaker IDs and the sound effects and music cues that carry meaning.

  • Speaker identification
  • Non-dialogue audio described
  • Meets accessibility requirements

Subtitles or captions? The two terms are often used interchangeably. Strictly, subtitles translate the dialogue for viewers who can hear the audio, while captions are same-language and add speaker labels and sound cues for viewers who cannot. We produce either — translated Slovak subtitles or same-language Slovak captions and SDH — in whichever form your platform and audience require.

How can we help you?

Your project manager has everything covered

One point of contact from brief to delivery, and both a linguistic and a technical check on every file.

1

Brief review

We review your video, your audience and the player, including whether the platform re-wraps long cues on its own or honours the breaks we send it.

2

Template and translation

Where needed, we create an English subtitle template first, then send it to a native Slovak subtitler.

3

Timing and quality checks

Subtitles are timed against the video and checked for reading speed, line length, breaks that fall on real Slovak syllables, and format compliance.

4

Delivery and display check

Files delivered in the format you need, with every two-line cue read back on screen rather than trusted to the grid.

Our standards

The specs we work to

Readable subtitles are a matter of measurable limits, not opinion. These are the defaults we apply to Slovak unless your style guide says otherwise.

42characters

Maximum per line

Netflix Slovak guide, same figure

2lines

Maximum on screen

Bottom-heavy, never one word on top

17chars/sec

Reading speed

13 for children, 20 in SDH

1second

Minimum duration

Seven seconds at the far end

Those figures match the Netflix Slovak style guide, which also asks for a bottom-heavy shape and no stray single word on the upper line. What is particular to Slovak happens inside the limit rather than at its edge: the break has to land on a real syllable boundary, and a Slovak syllable does not need a vowel in order to exist.

Slovak specifics

A rule about long syllables, and 46 letters to apply it to

The rhythmic rule is stated plainly: if two long syllables would end up side by side inside a word, the second one is shortened. It surfaces in ordinary inflection rather than in rare words (žen-ám but tráv-am, nos-ím but súd-im), so it is not a preference a translator can quietly drop to claw back a character. It also has exceptions, which is precisely why the work needs a native speaker and not a find-and-replace pass.

Slovak carries the longest alphabet in Europe, 46 letters, and the rhythmic rule is one of the things that sets it apart from Czech, where nothing of the kind applies. On a page the two languages look close enough that files get recycled between them. They are not interchangeable, and a Slovak viewer notices inside a sentence.

Around 5 million people speak Slovak natively, and it has been an official language of the European Union since Slovakia joined in 2004. Briefs reach us from EU institutional programmes, from the manufacturing and automotive sector that employs much of the country, and from broadcasters and platforms delivering into Slovakia against a written spec.

Most common questions

Can Slovak subtitles be split automatically by a tool?

Only up to a point. Most automatic wrapping looks for a vowel to decide where a syllable ends, and Slovak has syllables with no vowel at all — vlk, prst, krk, štvrť. A tool that splits those in the middle produces something no Slovak reader parses as a word. We let a tool propose the break and a native subtitler confirm or move it before the file is timed.

Our Slovak file shows words with no vowels. Is the text corrupted?

No, that is normal Slovak. The letters r and l can carry a syllable on their own, which is why perfectly ordinary words are spelled without any vowel. Long versions of the same letters, ŕ and ĺ, do the same job and are always syllabic. Nothing has been lost in transfer; the file is intact and the word is spelled the way the dictionary spells it.

What is the rhythmic rule, and does it affect our subtitles?

It affects condensing. Slovak does not allow one long syllable to follow another inside the same word, so if two would meet, the second gets shortened. That removes some of the shorter word forms a translator might otherwise reach for to bring a line under the limit. It is why cutting a Slovak cue is a rewriting job rather than a trimming job, and why we hand it to a native speaker.

We have Czech subtitles already. Can they be adapted for Slovakia?

Adapted, yes; relabelled, no. The two languages are close in appearance and a reused file reads as a reused file very quickly. The rhythmic rule is one of the clearest dividing lines, and Czech has no equivalent of it — it changes word endings all the way through a script. Starting from your Czech file is usually the economical route, but it is editorial work by a Slovak linguist.

What does Slovak subtitling cost per minute?

Rates open at £18 per minute of running video. The figure moves with how long the video is, whether we type the audio up before spotting, whether you need an accessibility version or a burnt-in master, and how many formats are on the delivery list. Each job is quoted on its own and the Price Match Promise sits behind the number.

Do you caption Slovak footage in Slovak, not only translate it?

Regularly. Slovak audio gets Slovak captions and SDH, with speaker labels and the non-dialogue sound a viewer would otherwise miss. It is what an accessibility review looks for and what a muted social feed needs to work at all. Same-language files get the same break-point checking as translated ones, because the line limit does not care where the text came from.

We already have a Slovak transcript. Can you time it to picture?

Yes, and it usually shortens the job. We spot your transcript or SRT against the video, then re-cut any line that runs over the limit — which is where most inherited Slovak files need attention, since breaks made for a page are not breaks made for a two-line box. With no transcript, our team types the audio up here first and the same QA follows.

Will your Slovak files open in our editing software?

Yes. SRT, VTT, STL and TTML go straight into Premiere Pro, Final Cut Pro, DaVinci Resolve, Media Composer and the browser editors the platforms provide. One thing worth flagging: some upload tools re-wrap long cues to their own width and discard our breaks. Tell us the destination and we will size the lines for it, or deliver a burnt-in master so nothing can move.
