Swahili subtitling services

Corporate video, eLearning, documentary, broadcast and advertising, subtitled by native Swahili linguists. We write for the market you are aiming at rather than an average of two, and deliver in your platform's format. Swahili subtitles, voice over scripts and translation all sit inside one project.

About Swahili subtitling

One standard, and two answers to every borrowed word

Written Swahili has a single agreed standard, and it comes from Kiunguja, the speech of Zanzibar City, chosen at a conference in Mombasa in 1928. What the standard does not settle is how much English a sentence is allowed to keep. Tanzania reaches for the Swahili form; Kenya is comfortable leaving the English one where it fell.

On screen that shows up in plain nouns, not in style. A television is luninga in Dar es Salaam and TV in Nairobi; a traffic jam is foleni or jam. Each of those appears every time the thing itself does, so a file written for one country announces itself to the other within a scene or two — and luninga spends seven of the line's characters where TV spends two.

At GoLocalise, we ask which market the video is for before a word is written, build the terminology list around that answer, and put a native subtitler from that country on the file. Swahili translation of scripts and on-screen text runs through the same team and the same list.

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 Swahili it fixes the terminology at delivery, which is worth getting right first time since a burnt-in master cannot be re-pointed at another market.

  • Always visible
  • Terminology fixed at delivery
  • 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 Swahili subtitles or same-language Swahili 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, starting with which country the Swahili is for and what your existing materials already say.

2

Template and translation

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

3

Timing and quality checks

Subtitles are timed against the video and checked for reading speed, line length, terminology held to the agreed market, and format compliance.

4

Delivery and display check

Files delivered in the format you need, with the terminology list handed over so the next video matches this one.

Our standards

The specs we work to

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

42characters

Maximum per line

Terminology decides how far it goes

2lines

Maximum on screen

Bottom-weighted and centred

17chars/sec

Reading speed

13 where the audience is children

1second

Minimum duration

Up to seven seconds on screen

No platform publishes a Swahili subtitle style guide, so these limits are ours, and they hold for a language written in the Latin alphabet. What shifts inside them is the wording. A Swahili coinage is often several characters longer than the English word it stands in for, so the market you are writing for changes how much of a sentence fits on one line. We condense to fit; we do not truncate.

Swahili specifics

Who approves a new Swahili word, and who does not wait

Tanzania has a body for this. BAKITA was created by statute in 1967 and other institutions may propose terminology, but it is the one that approves it, which is how the Swahili alternative to an English word tends to exist there before anyone needs it. Kenya's equivalent, founded in 1998, researches and promotes the language rather than ruling on usage, and everyday Kenyan Swahili borrows freely.

Kenya also has sheng, a fast-moving mix of Swahili, English and other local languages that keeps ordinary speech close to English, while Tanzanian usage stays noticeably uniform from one end of the country to the other. For a subtitler that difference is not a matter of taste: it decides which word goes on screen, and a viewer registers the wrong one immediately even though the sentence around it is correct.

The audience is large enough to make the choice worth making. Estimates put Swahili use at around 150 to 200 million people, first and second language together. It is the national language of Tanzania and of Kenya, where it has been official since 2010, a national language in the DRC, official in Uganda since 2022, one of the three official languages of the East African Community and a working language of the African Union.

Most common questions

Is Swahili for Tanzania and Swahili for Kenya the same file?

The grammar and the spelling are shared, so a Kenyan viewer follows a Tanzanian file without difficulty. What differs is vocabulary, particularly wherever English offered a word and one country took it. Over a full video those choices add up into an accent on the page, so for anything public-facing we write to one market and say which on the delivery note.

Which Swahili should we choose for a pan-African campaign?

Usually the Tanzanian standard, because it is the one taught and broadcast most widely and it travels furthest beyond the two countries. If the campaign is built on Kenyan media, Kenyan talent or a Nairobi audience, the Kenyan register is the better fit. We will recommend one at the brief and keep it consistent across every video in the run.

Can you match the Swahili terminology we already use?

Yes, and that is normally the shortest route. Send whatever you have: a glossary, an old subtitle file, your website. We will build the list from it so this video sounds like the last one rather than starting an argument with it. Where your existing material mixes the two conventions, we will flag the entries and ask you to choose.

Should Swahili subtitles include English words at all?

Sometimes, and it depends on the audience rather than on principle. Technical, medical and financial content often reads more naturally with the English term kept, especially for a Kenyan audience. A Tanzanian public-sector or broadcast brief usually wants the Swahili form. Your subtitler decides case by case within the convention we agreed, rather than applying one rule to the whole script.

How much does Swahili subtitling cost?

Swahili subtitling is quoted by the minute of video, from £20. Setting the terminology to your market and keeping it there is part of that rate, not an extra line. Beyond it, the figure follows running time, whether a transcript exists already, whether SDH or an open-caption master is needed, 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 Swahili audio as well as translating into Swahili?

Both. Captioning footage that is already in Swahili is what accessibility work and muted social feeds need, and translated subtitles bring other content to a Swahili audience. Captioning raises the market question in a sharper form, because a speaker from one country may be using words your audience in the other would not, and the captions have to stay faithful to what was said.

We have a Swahili transcript or SRT already. Can you work from it?

Send it over. We spot and time against what you have, and the first pass reads for consistency, since files assembled over time tend to carry terms from both countries in the same document. Where there is no transcript we produce one from the audio. Either route gets the same linguistic and technical QA before anything is delivered.

Will your Swahili subtitle files open in our editing software?

They will. Swahili SRT, VTT, STL and TTML go straight into Premiere Pro, Final Cut Pro, DaVinci Resolve and the browser-based editors, and since the language is written in ordinary Latin letters nothing is at risk in the conversion. If you would rather the wording be settled before the file leaves your hands, take a burnt-in MP4 or MOV.
