Thai data for AI training, collected to your brief
Thai data from IndecalAI is collected or reviewed by a native Thai 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 Thai data can we produce?
Thai data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Thai 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 Thai 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 Thai before you brief it
Thai is the national language of Thailand, taught in schools everywhere, while regional languages such as Northern Thai, Isan and Southern Thai remain common at home and in local markets.
Thai is written without spaces between words, so any text pipeline needs a segmenter and a clear rule for what counts as a word. It has five tones that carry meaning but are not marked in writing, which is why spoken data should be checked by native listeners. Polite particles change with the speaker, so decide the register your product should use, because customer-facing speech and casual chat read very differently.
Languages that sit close to Thai in script, family or region: Lao data, Khmer data, Burmese data, Vietnamese data, Cantonese data and Malay 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 Thai data
Each links to the service that runs it, with its full scope and process.
Thai speech data
Recorded speech in Thai: calls, prompts and voice bot utterances, matched to the region and reviewed before delivery.
Thai text data
Written Thai: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.
Thai conversational data
Scripted or spontaneous Thai dialogue for voice bots, support agents and customer-facing assistants across this region's markets.
Thai translation
Human-verified translation between Thai and another language, covering prompts, UI copy and training data.
What to put in a Thai brief
Four things worth deciding before contributors start, so the first sample already looks right.
Region or dialect
Thai is spoken mainly in Thailand. Worth naming in a brief: Central Thai (Bangkok standard), Northern, Northeastern (Isan) and Southern speech. Tell us the region or community you're targeting so contributors are matched to the right one.
Script or transliteration
Script for Thai: Thai script, 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 Thai data
One named contact owns the project from scoping to the last file.
Brief
You tell us the data type, the Thai 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 Thai data ends up
Common jobs for Thai data. They're examples of the work, not a client list.
Voice bots and IVR
Recorded Thai prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.
Support chat and tickets
Everyday Thai messages, written in the domain you work in, give a chat assistant real phrasing to learn from.
Content moderation and sentiment
Labeled Thai 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 Thai so a product reads like it was written for that market, not machine-translated.
Off-the-shelf Thai 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 Thai: see the Thai speech dataset. Here's how the two paths compare.
| Topic | A typical off-the-shelf dataset | Thai data with us |
|---|---|---|
| Already collected? | No way to know until you've already paid for it | Yes: roughly 500 hours of Thai 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 |
Thai data terms, in plain words
General definitions. They describe the field, not a claim about us.
Where Thai data fits
Thai is one of 100 languages on our languages directory. You can also browse every category on the datasets hub.
Do you support Thai?
Yes. Thai 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 Thai data collected?
Yes. Roughly 500 hours of Thai speech, prompts and conversations are already recorded and ready to license. The Thai speech dataset page has the details, and anything it doesn't cover we collect to your brief.
Can you mix regional varieties of Thai 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 Thai?
Speech, text, conversational data and translation to or from Thai. Image and video categories don't depend on language, so Thai 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 Thai?
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 Thai 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 Thai should I ask for?
Ask for the one your users actually speak. Thai is spoken mainly in Thailand, and the forms most worth naming in a brief are Central Thai (Bangkok standard), Northern, Northeastern (Isan) and Southern 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 Thai written, and does it matter for the data?
Thai data uses Thai script, 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.
