Korean data for AI training, collected to your brief
Korean data from IndecalAI is collected or reviewed by a native Korean speaker, not pulled from an existing archive. We work with speakers across East and Southeast Asia, where writing systems and speech patterns vary widely from one market to the next, matched to your brief and checked before delivery.
What Korean data can we produce?
Korean data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Korean speaker for your brief, not pulled from an existing archive.
Writing systems, formality levels and spoken rhythm shift noticeably across East and Southeast Asia, so a brief written for one market rarely transfers cleanly to the next without a native reviewer checking 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 Korean and another language.
Image and video categories on our datasets hub don't depend on language at all, so a project can combine this with visual data from the same region.

What to know about Korean before you brief it
Korean is spoken across the whole Korean peninsula and by communities in China, Japan, Central Asia and the United States. The writing system, Hangul, was designed in the fifteenth century and is widely admired for how systematically it is built.
Speech levels are built into the grammar: the same request changes its ending depending on who is talking to whom, so a voice assistant for elderly customers and one for teenagers need different data. Regional accents such as Gyeongsang and Jeolla are quite distinct from Seoul speech, and vocabulary has drifted apart between the two Koreas. Name the audience and the setting in the brief.
Languages that sit close to Korean in script, family or region: Japanese data, Mandarin Chinese data, Mongolian data, Cantonese data, Vietnamese data and Thai 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 Korean data
Each links to the service that runs it, with its full scope and process.
Korean speech data
Recorded speech in Korean: calls, prompts and voice bot utterances, matched to the region and reviewed before delivery.
Korean text data
Written Korean: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.
Korean conversational data
Scripted or spontaneous Korean dialogue for voice bots, support agents and customer-facing assistants across this region's markets.
Korean translation
Human-verified translation between Korean and another language, covering prompts, UI copy and training data.
What to put in a Korean brief
Four things worth deciding before contributors start, so the first sample already looks right.
Region or dialect
Korean is spoken mainly in South Korea and North Korea, with communities in China, Japan and the United States. Worth naming in a brief: Seoul standard, Gyeongsang speech, Jeolla speech, Jeju. Tell us the region or community you're targeting so contributors are matched to the right one.
Script or transliteration
Script for Korean: Hangul, 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 Korean data
One named contact owns the project from scoping to the last file.
Brief
You tell us the data type, the Korean 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 Korean data ends up
Common jobs for Korean data. They're examples of the work, not a client list.
Voice bots and IVR
Recorded Korean prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.
Support chat and tickets
Everyday Korean messages, written in the domain you work in, give a chat assistant real phrasing to learn from.
Content moderation and sentiment
Labeled Korean 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 Korean so a product reads like it was written for that market, not machine-translated.
Off-the-shelf Korean 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 Korean: see the Korean speech dataset. Here's how the two paths compare.
| Topic | A typical off-the-shelf dataset | Korean data with us |
|---|---|---|
| Already collected? | No way to know until you've already paid for it | Yes: roughly 500 hours of Korean 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 |
Korean data terms, in plain words
General definitions. They describe the field, not a claim about us.
Where Korean data fits
Korean is one of 100 languages on our languages directory. You can also browse every category on the datasets hub.
Do you support Korean?
Yes. Korean 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 Korean data collected?
Yes. Roughly 500 hours of Korean speech, prompts and conversations are already recorded and ready to license. The Korean speech dataset page has the details, and anything it doesn't cover we collect to your brief.
Can you mix regional varieties of Korean 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 Korean?
Speech, text, conversational data and translation to or from Korean. Image and video categories don't depend on language, so Korean 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 Korean?
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 Korean 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 Korean should I ask for?
Ask for the one your users actually speak. Korean is spoken mainly in South Korea and North Korea, with communities in China, Japan and the United States, and the forms most worth naming in a brief are Seoul standard, Gyeongsang speech, Jeolla speech, Jeju. If you are unsure, describe your users and where they live, and your named contact will help you decide before collection starts.
How is Korean written, and does it matter for the data?
Korean data uses Hangul, 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.
