Yoruba subtitling services
Corporate video, eLearning, documentary, broadcast and advertising, subtitled by native Yoruba linguists. The accent above and the dot below arrive on the same letter, set the same way from the first cue to the last. Yoruba subtitles, voice over scripts and translation all sit inside one project.
About Yoruba subtitling
Two marks on one vowel, and no single character to hold them
Yoruba marks two different things on the same letter. An acute or grave accent carries the tone, high or low, while an underdot on ẹ, ọ and ṣ marks a different vowel or consonant altogether. When a word needs both at once they stack on one character, as in ọ́ and ẹ̀: one mark above the letter, one below it, and each of them changing which word you are reading.
Unicode has no single character for that pairing. ọ́ is two code points, o-with-dot-below followed by a combining acute, and it stays two however you normalise it, because there is nothing to normalise it into. The letter is assembled at the moment it is drawn, and a font whose spacing only anticipates a mark above or a mark below positions the second one by guesswork.
At GoLocalise, we work with native Yoruba subtitlers, hold one encoding across the whole file instead of whatever each tool along the way happened to produce, and look at the finished letter in the font your platform actually serves. It is a character that gets built on screen, so on screen is where it has to be checked.


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 inSubtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for social feeds that autoplay muted — and in Yoruba it means the letter is assembled once, by us, instead of by every player it reaches.
- Always visible
- Marks positioned once, by us
- Delivered as a finished video file
Closed captions
SwitchableA 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
AccessibilitySubtitling 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 Yoruba subtitles or same-language Yoruba 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.
Brief review
We review your video, your audience and the player, including how its font handles a vowel carrying an accent above and a dot below at once.
Template and translation
Where needed, we create an English subtitle template first, then send it to a native Yoruba subtitler.
Timing and quality checks
Subtitles are timed against the video and checked for reading speed, line length, one consistent encoding for every marked letter, and format compliance.
Delivery and display check
Files delivered in the format you need, with the stacked letters looked at in the destination font rather than taken on trust.
Our standards
The specs we work to
Readable subtitles are a matter of measurable limits, not opinion. These are the defaults we apply to Yoruba unless your style guide says otherwise.
Maximum per line
A marked letter is one letter
Maximum on screen
Bottom-weighted, broken at the phrase
Reading speed
Slower for dense on-screen text
Minimum duration
Up to seven at the top end
Netflix has no published timed-text guide for Yoruba, so these four figures are ours. The alphabet is Latin and the letters take Latin width, so the character limit and the reading speed apply as they would to any European language. The step we add before delivery is the encoding: the same marked letter has more than one valid form, and a file that reaches us mixed leaves us consistent.
Deliverables
Professional subtitle formats
We adapt your existing translations into subtitle format or create subtitles from scratch, in Yoruba, English or any other language. And if the project needs a timed script or a plain document instead, we deliver that too.
Standard text-based
Compatible with most platforms and players.
Broadcast & professional
For broadcasters, post houses and streaming delivery specs.
Burnt-in video
A finished file with the subtitles baked into the picture, both marks in place.

Yoruba specifics
Where the marks go missing, and the two forms of one letter
Around 48 million people speak Yoruba as a first language, mainly in south-western Nigeria and across the border in Benin and Togo, and it holds national status in Nigeria. It supports a large film and television industry of its own, along with music, religious broadcasting and a diaspora audience that consumes most of it online. Almost all of that material is published text, held to the written standard rather than to what a phone keyboard happens to offer.
Which is the difficulty, because casual Yoruba is frequently typed with no tone marks at all, and sometimes with the underdots gone too. Restoring them automatically is still an open research problem rather than a solved one, and the reason is simple: the mark is not decoration that can be inferred from spelling, it is part of which word was said. Its neighbour Igbo settled the same question the other way and leaves tone off the page entirely. Yoruba writes it, so leaving it out is an omission.
There is also more than one correct way to encode the same letter. Fully composed, ọ́ is o-with-dot-below plus a combining acute, two code points; fully decomposed it is a plain o, then a combining dot below, then the acute, three. Both are valid, both look identical on screen, and they are different strings to anything comparing text. A file that mixes the two is not corrupt, but it will break search, sorting and any automated check run over it.

Most common questions
Why do the accents on our Yoruba subtitles sit crooked?
Because that letter is built rather than stored. A vowel like ọ́ carries a dot below and an accent above, and Unicode has no single character for the pair, so the accent arrives as a separate combining mark for the font to place. A font that only ever expected one mark puts the second wherever its default rule says, which is why the result can drift off-centre or crowd the dot. We look at it in the font you ship to.
Can you deliver Yoruba subtitles without the tone marks?
We would advise against it, and here is why. In Yoruba the accent is not emphasis, it is part of which word is on screen, so a file stripped of tone marks reads to a Yoruba audience the way missing letters would read to an English one. Informal typing does drop them, but published and broadcast Yoruba does not. If your delivery spec genuinely requires plain ASCII, tell us at the brief and we will talk it through.
Our Yoruba file has the underdots but no accents. Is that a problem?
It is a common state for a file to arrive in, and it needs fixing rather than passing through. The underdot and the tone mark do separate jobs: the dot tells you which vowel, the accent tells you which word. Having one without the other is half a spelling. A native Yoruba subtitler puts the tone back by working against the audio, because the mark follows what was said and cannot be worked out from the letters alone.
Which Unicode form do you deliver Yoruba subtitles in?
One form, consistently, and we will match whatever your spec asks for. The composed form writes ọ́ as two code points and the decomposed form as three; both are correct Unicode and both look the same in a player. What causes trouble is a file carrying both, because search, sorting, subtitle QC tools and translation memories will treat the two spellings as unrelated. We normalise once and hold it to the last cue.
What does Yoruba subtitling cost per minute?
Yoruba subtitling is priced by the minute of finished video, from £20, and the Yoruba-specific work is inside that rate rather than added to it. The figure moves with running time, whether we transcribe before translating, whether you need SDH or a burned-in version, and how many output formats leave with the job. Every project is quoted on its own, with the Price Match Promise behind it.
Do you caption Yoruba footage in Yoruba, or only translate into it?
Both, and they are separate pieces of work. Translating an English video into Yoruba subtitles is one job; same-language Yoruba captions and SDH for footage already in Yoruba is another. The second is where tone marking matters most, because the subtitler is writing down what a speaker actually said and can place every accent from the recording rather than inferring it from a script.
We have a Yoruba transcript already. Will you work from it?
Yes, send it across. We spot and time against your transcript or SRT, and the first thing we look at is the state of the marked letters: whether the accents are there at all, and whether the file is using one encoding or two. Without a transcript we work from the Yoruba audio instead. Either route, the file gets the same linguistic and technical QA before it goes back.
Do your Yoruba subtitle files open in our editing software?
They do. Yoruba SRT, VTT, STL and TTML import into Premiere Pro, Final Cut Pro, DaVinci Resolve and the browser-based editors with both marks intact. What to watch for is a tool that re-normalises text on import and silently changes the encoding of every marked letter, so we re-check after any conversion in your chain. To take the font out of the question altogether, we deliver a burned-in MP4 or MOV.
