Yoruba data for AI training, collected to your brief
Yoruba data from IndecalAI is collected or reviewed by a native Yoruba 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 Yoruba data can we produce?
Yoruba data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Yoruba 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 Yoruba 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 Yoruba before you brief it
Yoruba is the language of southwestern Nigeria, including Lagos, and of communities in Benin and Togo, and its religious and cultural traditions traveled to the Americas.
Yoruba is tonal, with three tones, and the proper spelling marks them with accents and uses dots below certain letters. In everyday digital writing these marks are mostly left off, which leaves many words ambiguous for a machine. A project should say whether to deliver text with full marks, which is what most speech and language technology needs, or in the plain form people actually type.
Languages that sit close to Yoruba in script, family or region: Igbo data, Twi data, Hausa data, Fulani data, Wolof data and English 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 Yoruba data
Each links to the service that runs it, with its full scope and process.
Yoruba speech data
Recorded speech in Yoruba: calls, prompts and voice bot utterances, mixed with French, English or Arabic if that reflects how people actually speak it.
Yoruba text data
Written Yoruba: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.
Yoruba conversational data
Scripted or spontaneous Yoruba dialogue for voice bots and support agents, reflecting how speakers here actually mix languages.
Yoruba translation
Human-verified translation between Yoruba and French, English, Arabic or another language in the same project.
What to put in a Yoruba brief
Four things worth deciding before contributors start, so the first sample already looks right.
Region or dialect
Yoruba is spoken mainly in southwestern Nigeria, Benin and Togo, with a diaspora in the Americas. Worth naming in a brief: Standard Yoruba, Oyo, Ijebu and Ekiti speech. Tell us the region or community you're targeting so contributors are matched to the right one.
Script or transliteration
Script for Yoruba: Latin letters with tone marks and dots below some 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 Yoruba data
One named contact owns the project from scoping to the last file.
Brief
You tell us the data type, the Yoruba 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 Yoruba data ends up
Common jobs for Yoruba data. They're examples of the work, not a client list.
Voice bots and IVR
Recorded Yoruba prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.
Support chat and tickets
Everyday Yoruba messages, written in the domain you work in, give a chat assistant real phrasing to learn from.
Content moderation and sentiment
Labeled Yoruba 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 Yoruba so a product reads like it was written for that market, not machine-translated.
Off-the-shelf Yoruba 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 Yoruba: see the Yoruba speech dataset. Here's how the two paths compare.
| Topic | A typical off-the-shelf dataset | Yoruba data with us |
|---|---|---|
| Already collected? | No way to know until you've already paid for it | Yes: roughly 500 hours of Yoruba 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 |
Yoruba data terms, in plain words
General definitions. They describe the field, not a claim about us.
Where Yoruba data fits
Yoruba is one of 100 languages on our languages directory. You can also browse every category on the datasets hub.
Do you support Yoruba?
Yes. Yoruba 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 Yoruba data collected?
Yes. Roughly 500 hours of Yoruba speech, prompts and conversations are already recorded and ready to license. The Yoruba speech dataset page has the details, and anything it doesn't cover we collect to your brief.
Can you mix regional varieties of Yoruba 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 Yoruba?
Speech, text, conversational data and translation to or from Yoruba. Image and video categories don't depend on language, so Yoruba 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 Yoruba?
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 Yoruba 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 Yoruba should I ask for?
Ask for the one your users actually speak. Yoruba is spoken mainly in southwestern Nigeria, Benin and Togo, with a diaspora in the Americas, and the forms most worth naming in a brief are Standard Yoruba, Oyo, Ijebu and Ekiti 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 Yoruba written, and does it matter for the data?
Yoruba data uses Latin letters with tone marks and dots below some 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 Yoruba data
Pick the data type, confirm Yoruba as the language and a rough volume, and send it. We'll produce a small sample free before you commit.
