Lingala data for AI training, collected to your brief
Lingala data from IndecalAI is collected or reviewed by a native Lingala speaker, not pulled from an existing archive. We work with speakers across Africa, frequently alongside French, English or Arabic in the same conversation, matched to your brief and checked before delivery.
What Lingala data can we produce?
Lingala data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Lingala speaker for your brief, not pulled from an existing archive.
Speakers here often move between this language and French, English or Arabic within the same conversation, so a brief should say whether to keep that mixing or avoid it.
This sits across several of our services depending on what you need: data collection for raw speech or text, conversational AI data for dialogue, and translation and localization for converting between Lingala and another language.
Translation projects often pair this language with French, English or Arabic. See translation and localization for that scope.

What to know about Lingala before you brief it
Lingala is a lingua franca on the Congo river and is the language of Kinshasa and Brazzaville, as well as of the music that carried it across Africa. It is also used by the army and in many media.
Everyday Lingala mixes in a lot of French, so a transcript of a real conversation will not look like the formal written language taught in books. Decide what you want recorded. Tone and the open vowels are written with marks that casual typing often skips, which can make text ambiguous. The Lingala of Kinshasa and of Brazzaville differ in vocabulary, so name the city.
Languages that sit close to Lingala in script, family or region: Swahili data, Kinyarwanda data, French data, Zulu data, Wolof data and Xhosa data.
Deciding what to specify for any language? The guide to speech data collection covers the choices that apply across languages, and the one on transcription for AI and for people covers how speech becomes text.

Four ways to request Lingala data
Each links to the service that runs it, with its full scope and process.
Lingala speech data
Recorded speech in Lingala: calls, prompts and voice bot utterances, mixed with French, English or Arabic if that reflects how people actually speak it.
Lingala text data
Written Lingala: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.
Lingala conversational data
Scripted or spontaneous Lingala dialogue for voice bots and support agents, reflecting how speakers here actually mix languages.
Lingala translation
Human-verified translation between Lingala and French, English, Arabic or another language in the same project.
What to put in a Lingala brief
Four things worth deciding before contributors start, so the first sample already looks right.
Region or dialect
Lingala is spoken mainly in the Democratic Republic of the Congo and the Republic of the Congo. Worth naming in a brief: Kinshasa Lingala, Brazzaville Lingala, Lingala of the Congo river. Tell us the region or community you're targeting so contributors are matched to the right one.
Script or transliteration
Script for Lingala: Latin letters with marks for tone and open vowels, left to right. Say whether you want the native script, a transliterated version, or both, especially if your downstream system only reads one.
Data type mix
Speech, text, conversational and translation can be requested together or on their own. Tell us the mix your model needs.
Volume and timeline
A rough sense of how much data and how soon lets us staff the right number of contributors from the start.
From your brief to reviewed Lingala data
One named contact owns the project from scoping to the last file.
Brief
You tell us the data type, the Lingala variety or region and roughly how much you need.
NDA and scope
We sign an NDA before any data moves, then agree the scope with you.
Free sample
We produce a small sample free, so you can check it before you commit.
Production
Contributors from our network work in our own tools, to the brief you set.
Review
A review pass runs before anything is delivered.
Delivery
The data comes to you, or moves on to another service with us.
Where Lingala data ends up
Common jobs for Lingala data. They're examples of the work, not a client list.
Voice bots and IVR
Recorded Lingala prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.
Support chat and tickets
Everyday Lingala messages, written in the domain you work in, give a chat assistant real phrasing to learn from.
Content moderation and sentiment
Labeled Lingala posts, reviews and messages teach a model to read tone and intent correctly in this language.
Localizing a product
Translating prompts, UI copy and training data into Lingala so a product reads like it was written for that market, not machine-translated.
Off-the-shelf Lingala data, or built to your brief?
We hold around 35,000 hours of off-the-shelf speech, prompts and conversations already collected across our network. We can't promise Lingala is in that pool until you ask, but it's worth checking before you commission a fresh collection. Here's how the two paths compare.
| Topic | A typical off-the-shelf dataset | Lingala data with us |
|---|---|---|
| Already collected? | No way to know until you've already paid for it | We check our ~35,000-hour speech and conversation pool first and tell you honestly either way |
| Fit to your brief | Built for whoever bought it first, not your exact region, register or use case | Collected or reviewed to the region, script and format you specify |
| Who else has it | The same files can be sold to more than one buyer | Scoped to your engagement, never resold for unrelated projects |
| Checking the fit | You find out after you've already paid for it | A small free sample first, so you check it before committing to volume |

Questions about Lingala data
The datasets FAQ covers questions that apply across every category.
Do you support Lingala?
Yes. Lingala is one of 100 languages in this directory, part of our wider language coverage worldwide, including deep Indian language coverage. Tell us the regional variety you need.
Do you already have any Lingala data collected?
Maybe. We hold around 35,000 hours of off-the-shelf speech, prompts and conversations across our network, but we can't promise Lingala is in that pool until you ask. It costs nothing to check before you commission a fresh collection.
Can you mix regional varieties of Lingala in one project?
Yes. Tell us the mix of regions or dialects you need and we'll match contributors from our network to that brief.
Which data types are available in Lingala?
Speech, text, conversational data and translation to or from Lingala. Image and video categories don't depend on language, so Lingala speakers can also appear in those briefs on request.
Is a sample available before we commit?
Yes, a small free sample first.
Can this run alongside other languages in the same project?
Yes. Many engagements mix languages, domains and data types under one brief and one named contact, using our network of 30,000+ people across 150+ projects delivered so far.
What counts as a regional variety of Lingala?
A version of the language tied to a place or community, which can differ in vocabulary, pronunciation, formality or script from another region's variety. Name the region in your brief if it matters for your use case.
Can you handle Lingala in its native script?
Yes. Contributors work in the native script by default, with transliteration available if your project needs it instead.
Which variety of Lingala should I ask for?
Ask for the one your users actually speak. Lingala is spoken mainly in the Democratic Republic of the Congo and the Republic of the Congo, and the forms most worth naming in a brief are Kinshasa Lingala, Brazzaville Lingala, Lingala of the Congo river. If you are unsure, describe your users and where they live, and your named contact will help you decide before collection starts.
How is Lingala written, and does it matter for the data?
Lingala data uses Latin letters with marks for tone and open vowels, left to right. The script and its encoding affect how a model reads the data, so say in the brief which one you need and whether a romanized or transliterated version is also required.
