About Lingala subtitling

The two letters your keyboard does not have

The Lingala alphabet runs to 35 letters and digraphs, and two of them are ɛ and ɔ, the open e and the open o. They are not accented versions of e and o. They are separate vowels of the written language, sitting alongside the close ones, and literary Lingala keeps all seven apart rather than treating any pair as interchangeable.

No mainstream operating system ships a Lingala keyboard layout, so the two letters are the first casualty of ordinary typing. Plenty of published Lingala goes out without them: books, newsletters, forum posts, even the Lingala translation of the Universal Declaration of Human Rights. And once e and o have been substituted in, nothing in the file marks where a distinction used to be.

At GoLocalise, we work with native Lingala subtitlers, agree at the brief which convention your file is written to and then hold it from the first cue to the last, and confirm the two characters on the platform you are shipping to instead of assuming they arrived.

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 Lingala it puts ɛ and ɔ into the image in our typeface, before any player gets to look for a substitute.

  • Always visible
  • ɛ and ɔ drawn in our typeface
  • 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 Lingala subtitles or same-language Lingala 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, and settle which Lingala convention the file follows before a word is written.

2

Template and translation

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

3

Timing and quality checks

Subtitles are timed against the video and checked for reading speed, line length, consistent use of ɛ and ɔ throughout, and format compliance.

4

Delivery and display check

Files delivered in the format you need, with the two open vowels confirmed on the destination player rather than assumed.

Our standards

The specs we work to

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

42characters

Maximum per line

ɛ and ɔ cost one character each

2lines

Maximum on screen

Bottom-weighted, split at the phrase

17chars/sec

Reading speed

Slower for development content

1second

Minimum duration

Up to seven at the top end

Netflix publishes no timed-text guide for Lingala, so these figures are ours rather than a platform's. The alphabet is Latin and takes Latin width, so the character limit and the reading speed transfer without adjustment. What has to be settled before anyone counts anything is which orthography the file uses, because that decision changes the spelling of a great many words on screen.

Lingala specifics

Which Lingala, and why fonts treat two letters as foreign

Lingala reaches roughly 21 million first-language speakers and another 20 million second-language ones, across the north-west of the Democratic Republic of the Congo and the northern half of the Republic of the Congo, and it is the everyday language of Kinshasa and Brazzaville. Music, radio, public health campaigns and NGO communication carry it far beyond that, which is why so much of the work reaching us is aimed at an audience larger than either country.

That range is also why the orthography question is a real one. Literary Lingala keeps all seven vowels distinct, and it is the form used in institutional, religious and educational material. Kinshasa Lingala has shifted the other way, with the open vowels merging into the close ones in speech, and writing there tends to follow. Neither is a mistake. But a file has to pick one, and picking it late means rewriting rather than proofreading.

The technical half is smaller and easier to fix. ɛ is U+025B and ɔ is U+0254, and both sit in the IPA Extensions block, which typeface designers treat as phonetic notation rather than as somebody's alphabet. A font can cover every other letter in a Lingala sentence and stop at those two, so the failure is rarely a whole line of boxes. It is two characters mid-word arriving in a visibly different face, or not arriving at all.

Most common questions

Should our Lingala subtitles use ɛ and ɔ, or e and o?

It depends on who is watching, and it is a decision for the brief rather than for QA. Institutional, religious and educational Lingala keeps the open vowels; a lot of Kinshasa-facing media does not, and its readers are used to seeing e and o. We will recommend one based on your audience and your existing material, then apply it consistently. What we avoid is a file that does both.

Why do ɛ and ɔ appear in a different font from the rest of the word?

Because of where they live in Unicode. The two characters sit in the IPA Extensions block, which many typefaces skip on the assumption it is phonetic notation rather than an alphabet in use. When the font in your player has no glyph for them, the system fetches one from somewhere else, and you get two letters mid-word in another design. Tell us the destination and we will check it there, or burn the subtitles in.

Our Lingala source was typed with e and o throughout. Can you restore it?

Yes, and it is a reading job rather than a conversion. Nothing in the file records which e was once an ɛ, so the letter has to be decided word by word from the meaning and, where we have it, from the audio. A native Lingala subtitler does that pass. If you would rather keep the file as it stands, that is a legitimate choice too, and we will say so at the brief.

Do you subtitle for both Kinshasa and Brazzaville from one file?

Usually yes, and we will tell you when it is not sensible. The written language is shared across the river and a single subtitle file normally serves both cities and the wider region. Where a script leans heavily on Kinshasa vocabulary, or where an institutional client needs the literary written form, we adapt rather than ship the same text twice. Your project manager raises it before work starts.

What does Lingala subtitling cost per minute?

Lingala subtitling is priced by the minute of finished video, from £20, and the Lingala-specific work sits inside that rate rather than on top of it. The figure moves with running time, whether we transcribe before translating, whether you want 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 Lingala footage in Lingala, or only translate into it?

Both. Translating an English or French video into Lingala subtitles is one job; same-language Lingala captions and SDH for footage already in Lingala is another, and we deliver either. The second is common in public health and development work, where the audience is listening in Lingala already and the captions exist for accessibility, for noisy rooms, or for social video playing muted.

We have a Lingala transcript already. Will you work from it?

Yes, send it over. We spot and time against your transcript or SRT, and the first pass establishes which orthography it was written in, so that everything added afterwards matches rather than drifting. If there is no transcript we work from the Lingala audio instead. Either route, the file gets the same linguistic and technical QA before it comes back to you.

Do your Lingala subtitle files open in our editing software?

They do. Lingala SRT, VTT, STL and TTML import into Premiere Pro, Final Cut Pro, DaVinci Resolve and the browser-based editors with the open vowels intact. The catch is display rather than import: an editor whose interface font lacks those two glyphs will show them oddly even though the file is fine. We check the finished output, not the editing window.
