What's in the Croatian speech dataset?
The IndecalAI OTS Croatian speech dataset is roughly 500 hours of Croatian speech, prompts and conversations, recorded by Croatian speakers in our network who all consented to commercial AI training. It's already recorded, so you can license it now instead of waiting on a new collection.
Croatia is a busy market for tourism, banking and telecom, and Croatian speech data is scarce next to bigger European languages. Its regional dialects are why speakers from across the country matter.
Every recording comes with a transcript and metadata about the speaker, the device and the setting, and you can take it as WAV, OGG or another common format. Every order starts with sample clips and a spec sheet, so you can match the data against your model before you agree a licence.
Need more than what's in stock? Croatian speakers from our 30,000+ network record new speech to your brief, and our Croatian data page covers what we collect to order.

What roughly 500 hours of Croatian speech looks like
Roughly 500 hours sounds abstract until you play it: about 21 days of Croatian speech without a pause. That's why we send sample clips and a spec sheet first, so you can judge the whole from a part.
- ~500 hours of Croatian speech
- ~30,000 minutes
- ~1.8M seconds of audio
- ~21 days, played back to back
Hours here are recorded audio. When you compare quotes, check whether each one counts audio hours or only the parts where someone is talking.

Croatian speech dataset, voice dataset or speech corpus?
Speech dataset, voice dataset, corpus: the names overlap. Here's how they differ, and where our Croatian data sits.
Croatian speech dataset
The general term
Recorded Croatian speech with details about each recording, for training and testing speech models. The name this page uses.
Croatian voice dataset
Usually the same thing
Some teams mean voice for text-to-speech or speaker recognition, which needs cleaner audio. Part of our data was recorded in a studio, so ask for those recordings.
Croatian audio dataset
A wider term
It can include music or background sound. Ours is speech audio: Croatian speech, prompts and conversations.
Croatian speech corpus
The research name
A structured collection of recordings and their details. Commercial datasets are corpora too, licensed instead of published.
Croatian ASR or speech-to-text dataset
Speech plus what was said
For training a model that turns Croatian audio into text. Every recording in our Croatian dataset comes with a transcript.
Serbo-Croatian speech data
Close relatives
Croatian, Serbian and Bosnian are mutually intelligible but differ in words and spelling. This dataset is Croatian.
What makes Croatian hard for speech recognition
These are the things a Croatian speech model trips on, and what to listen for in any Croatian sample, ours included.
English words inside Croatian
Croatian speakers mix in English for tech and work, with Croatian endings added. A model trained only on formal Croatian stumbles on that, so listen for it in a sample.
Croatian letters
Letters like č and ć sound close but are different, and people often drop the marks when they type. Check that the transcripts keep every Croatian letter.
Accents across Croatia
Zagreb, Split, Rijeka and Slavonian speech carry very different sounds and words. Check that the speaker mix covers the regions your users come from.
Words that differ from Serbian
Croatian and Serbian are close, but many everyday words differ, like kruh and hleb for bread. Transcripts have to use the Croatian forms.
What teams build with a Croatian speech dataset
Common uses for Croatian speech that's already recorded. They show the kind of work, and they aren't client names.
Croatian speech recognition
Train or fine-tune a Croatian speech-to-text model, or adapt a multilingual model so it handles Croatian well.
Voice bots and IVR
Teach a voice bot how Croatian callers actually ask for things, in the words and accents they use.
Customer service calls
Croatian speech for models that route, transcribe or summarize customer calls about accounts, orders and claims.
Voice in the car and at home
A Croatian base for in-car assistants and smart devices, before recording commands in the real setting.
Support and speech analytics
Croatian conversations for models that find intent, sentiment or topics in support calls and chats.
Testing a Croatian model
Held-back Croatian recordings your model never trained on, to measure word and character error rate before launch.
How many hours of Croatian speech do you need?
It depends on the model you start from and how close your users sound to the training data. These are rough starting points that come up often in speech work. Your own tests should decide.
| Goal | Rough starting point | With our Croatian data |
|---|---|---|
| Test a model you already have | A few hours your model never trained on | A test set cut from stock and kept out of training |
| Fine-tune a multilingual model, such as Whisper or wav2vec 2.0 | Tens to a few hundred hours | Roughly 500 hours in stock covers it |
| Adapt to one domain, like banking calls | A smaller set that sounds like your users | Stock as a base, plus a custom top-up in your domain |
| Train a Croatian model from scratch | Thousands of hours | Stock as a base, plus a larger custom collection |
Free Croatian speech datasets or a licensed one?
Public corpora such as Mozilla Common Voice, ParlaSpeech-HR and FLEURS have done a lot for Croatian speech research. They cover what their creators chose to record, like read sentences, crowd recordings or broadcast speech, and each comes with its own licence and terms of use. Here's how they compare with a licensed dataset.
| Topic | Public Croatian corpora | Our Croatian speech dataset |
|---|---|---|
| Licence | Set by each corpus, and some limit redistribution or changes | Agreed with you in writing, for what you're building |
| Consent | Covered by each project's own terms | Every speaker consented to commercial AI training |
| What it sounds like | Whatever the project recorded | Speech, prompts and conversations, with sample clips first |
| Who else trains on it | Anyone who downloads it | Set in the licence we agree with you |
| Filling gaps | Up to you | Recorded to your brief by the same network |
| Support | Community forums | A named contact from sample to delivery |
How to check a Croatian speech sample
Half an hour with the Croatian clips and the spec sheet answers most questions. The list works for any vendor, not only us.
| Check | What to look for | Where to find it |
|---|---|---|
| Accents | Speakers from the regions your users come from | The speaker mix on the spec sheet, and the clips |
| Everyday speech | The way your users really talk, including any mixing with other languages | Listen to the clips |
| Script | Transcripts in the script and spelling your model should output | The transcript format on the spec sheet |
| Audio | A sample rate and recording setup close to your product | The sample rate on the spec sheet |
| Numbers | Amounts, dates and phone numbers written one consistent way | Transcripts of the clips |
| Rights | Consent that covers commercial AI training, and a licence that fits | Ask for the licence terms before you buy |

Croatian speech data terms
The words that come up when you buy or build Croatian speech data. The full glossary covers every data type.
- Štokavian
- The dialect group standard Croatian, Serbian and Bosnian are based on.
- Ijekavian
- The form that says ije where Serbian says e, as in mlijeko for milk. Standard in Croatia.
- Kajkavian
- The dialect group spoken around Zagreb, quite different from standard Croatian.
- Speaker metadata
- Details recorded about each speaker, such as gender and age, that let you check the speaker mix against your users.
- OTS dataset
- Short for off-the-shelf dataset: data already collected and ready to license before a buyer asks for it, instead of recorded to one buyer's brief.
- Word error rate (WER)
- The share of words a speech model gets wrong against a reference transcript. Lower is better.
- Character error rate (CER)
- The same idea counted in characters, often used alongside WER, since small spelling differences can make WER look worse than the model is.
- Utterance
- One stretch of speech by one speaker, such as a single prompt read aloud or one turn in a conversation.

Questions about the Croatian speech dataset
Straight answers about licensing Croatian speech. The off-the-shelf FAQ covers questions that apply to every language.
Do you have a Croatian speech dataset ready to license?
Yes. Roughly 500 hours of Croatian speech, prompts and conversations are already recorded and ready to license, as part of our off-the-shelf speech pool.
What's in the Croatian speech dataset?
A mix of scripted prompts and natural conversations in Croatian, recorded on mobile phones, laptops and studio microphones, in quiet and noisy settings. Every recording comes with a transcript and metadata about the speaker, the device and the setting, in WAV, OGG or another common format.
Is this Croatian or Serbian?
This dataset is Croatian. The languages are close, so ask about the speaker mix on the spec sheet, and the sample clips let you hear it before you commit. Our Serbian dataset is separate.
Did every speaker consent to AI training?
Yes. Every speaker gave consent for their recordings to be used for commercial AI training.
How is the Croatian dataset licensed?
Licence terms are agreed with each customer, in writing, before delivery. That includes how you can use the data and whether anyone else can license the same recordings.
How much does the Croatian speech dataset cost?
We quote each order on its own, based on the hours you need and the licence terms. Send your request and your named contact comes back with a quote.
Can we hear Croatian samples first?
Yes. Ask and we send Croatian sample clips with the spec sheet, so you can check the audio before you commit.
What if we need more than 500 hours, or a specific accent?
We collect it. Croatian speakers from our network record new speech to your brief, such as a region, an age group, a device or a domain, and it can sit alongside the hours you license from stock.
Is this the same as a Croatian voice dataset or speech corpus?
For most uses, yes. Speech dataset, voice dataset, audio dataset and speech corpus are names for the same thing: recorded Croatian speech with details about each recording. If you need studio-quality voice for text-to-speech, ask for the recordings made in a studio.
Can we use it as a Croatian speech-to-text (ASR) dataset?
Yes. Every recording comes with a transcript, so it's ready for training and testing Croatian speech-to-text models. The spec sheet shows the transcript style, so you can check it matches your pipeline before you license it.
Why not use a free Croatian speech dataset?
Public Croatian corpora are a good start for research. Each one has its own licence and terms of use, and they cover what their creators chose to record, such as read sentences or broadcast speech. Read the licence before you train a commercial model on one, and check that it sounds like your users.
What does OTS mean?
OTS stands for off-the-shelf: data that's already recorded and ready to license, instead of collected after you order. Our OTS Croatian speech dataset is roughly 500 hours.
How many hours of Croatian speech do we need?
It depends on your starting model. A test set can be a few hours, fine-tuning a multilingual model often starts at tens to a few hundred hours, and training from scratch takes thousands. Your own tests should decide.
Can we fine-tune Whisper or wav2vec 2.0 on it?
Yes. Teams commonly fine-tune open speech models like these on licensed Croatian speech, and every recording comes with a transcript in WAV, OGG or another common format. The spec sheet shows the transcript style, so you can plan any conversion before you train.
Do you work with US teams?
Yes. We take calls in US Eastern mornings, which is evening in India. We're ISO 27001 certified, our SOC 2 report is available under NDA, and we sign GDPR data processing agreements and HIPAA business associate agreements on request.
