Czech data for AI training, collected to your brief
Czech data from IndecalAI is collected or reviewed by a native Czech speaker, not pulled from an existing archive. We work with speakers across Europe, with regional accents that a single generic model usually misses, matched to your brief and checked before delivery.
What Czech data can we produce?
Czech data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Czech speaker for your brief, not pulled from an existing archive.
Regional accents and dialect words inside a single country can trip up a model trained on one generic variety, so tell us the region or audience you're targeting.
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 Czech 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 Czech before you brief it
Czech is the official language of Czechia and is closely related to Slovak, with which it is mostly mutually understandable. It has a long written tradition and a rich literary history.
There is a real gap between the literary language of books and formal speech and the Common Czech heard in daily life, with different endings and some different words. A dataset for a voice product should lean toward Common Czech, while documents lean literary. Accents and hooks on letters carry meaning, and tools that strip them damage the text, so check that your pipeline preserves them.
Languages that sit close to Czech in script, family or region: Slovak data, Polish data, Croatian data, Ukrainian data, Russian data and German 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 Czech data
Each links to the service that runs it, with its full scope and process.
Czech speech data
Recorded speech in Czech: calls, prompts and voice bot utterances, built around the regional accent your model needs to recognize.
Czech text data
Written Czech: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.
Czech conversational data
Scripted or spontaneous Czech dialogue for voice bots and support agents, with the regional accent your users expect.
Czech translation
Human-verified translation between Czech and another language, covering prompts, UI copy and training data.
What to put in a Czech brief
Four things worth deciding before contributors start, so the first sample already looks right.
Region or dialect
Czech is spoken mainly in Czechia. Worth naming in a brief: Literary Czech, Common Czech (obecna cestina), Moravian speech. Tell us the region or community you're targeting so contributors are matched to the right one.
Script or transliteration
Script for Czech: Latin letters with accents, 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 Czech data
One named contact owns the project from scoping to the last file.
Brief
You tell us the data type, the Czech 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 Czech data ends up
Common jobs for Czech data. They're examples of the work, not a client list.
Voice bots and IVR
Recorded Czech prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.
Support chat and tickets
Everyday Czech messages, written in the domain you work in, give a chat assistant real phrasing to learn from.
Content moderation and sentiment
Labeled Czech 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 Czech so a product reads like it was written for that market, not machine-translated.
Off-the-shelf Czech 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 Czech: see the Czech speech dataset. Here's how the two paths compare.
| Topic | A typical off-the-shelf dataset | Czech data with us |
|---|---|---|
| Already collected? | No way to know until you've already paid for it | Yes: roughly 500 hours of Czech 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 |
Czech data terms, in plain words
General definitions. They describe the field, not a claim about us.
Where Czech data fits
Czech is one of 100 languages on our languages directory. You can also browse every category on the datasets hub.
Do you support Czech?
Yes. Czech 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 Czech data collected?
Yes. Roughly 500 hours of Czech speech, prompts and conversations are already recorded and ready to license. The Czech speech dataset page has the details, and anything it doesn't cover we collect to your brief.
Can you mix regional varieties of Czech 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 Czech?
Speech, text, conversational data and translation to or from Czech. Image and video categories don't depend on language, so Czech 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 Czech?
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 Czech 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 Czech should I ask for?
Ask for the one your users actually speak. Czech is spoken mainly in Czechia, and the forms most worth naming in a brief are Literary Czech, Common Czech (obecna cestina), Moravian 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 Czech written, and does it matter for the data?
Czech data uses Latin letters with accents, 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.
