Zulu data for AI training, collected to your brief
Zulu data from IndecalAI is collected or reviewed by a native Zulu 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 Zulu data can we produce?
Zulu data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Zulu 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 Zulu 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 Zulu before you brief it
Zulu is the most widely spoken home language in South Africa and is understood by many people who speak other Nguni languages, such as Xhosa. It is an official language of the country.
The grammar works through prefixes and noun classes, so a single word can carry the meaning of a whole English sentence, and recognizers built for English handle it poorly. The language includes click sounds written with c, q and x. In big cities like Johannesburg, speakers mix Zulu with English and other languages in everyday talk, so state whether you want pure or mixed speech.
Languages that sit close to Zulu in script, family or region: Xhosa data, Shona data, Swahili data, Kinyarwanda data, English data and Lingala 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 Zulu data
Each links to the service that runs it, with its full scope and process.
Zulu speech data
Recorded speech in Zulu: calls, prompts and voice bot utterances, mixed with French, English or Arabic if that reflects how people actually speak it.
Zulu text data
Written Zulu: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.
Zulu conversational data
Scripted or spontaneous Zulu dialogue for voice bots and support agents, reflecting how speakers here actually mix languages.
Zulu translation
Human-verified translation between Zulu and French, English, Arabic or another language in the same project.
What to put in a Zulu brief
Four things worth deciding before contributors start, so the first sample already looks right.
Region or dialect
Zulu is spoken mainly in South Africa, mainly KwaZulu-Natal and Gauteng. Worth naming in a brief: Standard isiZulu, urban Gauteng speech, KwaZulu-Natal rural speech. Tell us the region or community you're targeting so contributors are matched to the right one.
Script or transliteration
Script for Zulu: Latin letters, 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 Zulu data
One named contact owns the project from scoping to the last file.
Brief
You tell us the data type, the Zulu 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 Zulu data ends up
Common jobs for Zulu data. They're examples of the work, not a client list.
Voice bots and IVR
Recorded Zulu prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.
Support chat and tickets
Everyday Zulu messages, written in the domain you work in, give a chat assistant real phrasing to learn from.
Content moderation and sentiment
Labeled Zulu 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 Zulu so a product reads like it was written for that market, not machine-translated.
Off-the-shelf Zulu 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, and roughly 500 hours of it is Zulu: see the Zulu speech dataset. Here's how the two paths compare.
| Topic | A typical off-the-shelf dataset | Zulu data with us |
|---|---|---|
| Already collected? | No way to know until you've already paid for it | Yes: roughly 500 hours of Zulu speech are already recorded, and we tell you what they cover before you buy |
| 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 | Custom collections are scoped to your engagement. For stock data, who else can license it is set in your licence |
| 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 |
Zulu data terms, in plain words
General definitions. They describe the field, not a claim about us.
Where Zulu data fits
Zulu is one of 100 languages on our languages directory. You can also browse every category on the datasets hub.
Do you support Zulu?
Yes. Zulu 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 Zulu data collected?
Yes. Roughly 500 hours of Zulu speech, prompts and conversations are already recorded and ready to license. The Zulu speech dataset page has the details, and anything it doesn't cover we collect to your brief.
Can you mix regional varieties of Zulu 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 Zulu?
Speech, text, conversational data and translation to or from Zulu. Image and video categories don't depend on language, so Zulu 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 Zulu?
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 Zulu 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 Zulu should I ask for?
Ask for the one your users actually speak. Zulu is spoken mainly in South Africa, mainly KwaZulu-Natal and Gauteng, and the forms most worth naming in a brief are Standard isiZulu, urban Gauteng speech, KwaZulu-Natal rural speech. If you are unsure, describe your users and where they live, and your named contact will help you decide before collection starts.
How is Zulu written, and does it matter for the data?
Zulu data uses Latin letters, 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.
Request Zulu data
Pick the data type, confirm Zulu as the language and a rough volume, and send it. We'll produce a small sample free before you commit.
