What's in the Uzbek speech dataset?
The IndecalAI OTS Uzbek speech dataset is roughly 500 hours of Uzbek speech, prompts and conversations, recorded by Uzbek 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.
Uzbekistan is Central Asia's most populous country and a fast-growing market for mobile banking and telecom. Speech data for Uzbek is scarce, which makes licensed hours valuable.
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? Uzbek speakers from our 30,000+ network record new speech to your brief, and our Uzbek data page covers what we collect to order.

What roughly 500 hours of Uzbek speech looks like
Roughly 500 hours sounds abstract until you play it: about 21 days of Uzbek 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 Uzbek 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.

Uzbek speech dataset, voice dataset or speech corpus?
Speech dataset, voice dataset, corpus: the names overlap. Here's how they differ, and where our Uzbek data sits.
Uzbek speech dataset
The general term
Recorded Uzbek speech with details about each recording, for training and testing speech models. The name this page uses.
Uzbek 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.
Uzbek audio dataset
A wider term
It can include music or background sound. Ours is speech audio: Uzbek speech, prompts and conversations.
Uzbek speech corpus
The research name
A structured collection of recordings and their details. Commercial datasets are corpora too, licensed instead of published.
Uzbek ASR or speech-to-text dataset
Speech plus what was said
For training a model that turns Uzbek audio into text. Every recording in our Uzbek dataset comes with a transcript.
Uzbek speech recognition data
Speech plus what was said
For training a model that turns Uzbek audio into text. Every recording in our Uzbek dataset comes with a transcript.
What makes Uzbek hard for speech recognition
Where Uzbek speech recognition usually goes wrong, and how to spot it in a sample before you buy.
Russian words inside Uzbek
City speakers mix Russian words into Uzbek, especially for tech, money and work. A model trained only on formal Uzbek stumbles on that.
Latin or Cyrillic
Uzbek is written in both Latin and Cyrillic, and the oʻ and gʻ apostrophes are often typed in different ways. Check that the transcripts follow one standard.
Accents across Uzbekistan
Tashkent, Samarkand, Fergana and Khorezm speech differ in sounds and words. Check that the speaker mix covers the regions your users come from.
Long words built from suffixes
Uzbek adds suffixes to words, so one word can carry a lot of meaning. That makes WER harsh and real speech more important.
What teams build with an Uzbek speech dataset
The projects Uzbek speech data usually ends up in. They describe the work, not who it was for.
Uzbek speech recognition
Train or fine-tune an Uzbek speech-to-text model, or adapt a multilingual model so it handles Uzbek well.
Voice bots and IVR
Teach a voice bot how Uzbek callers actually ask for things, in the words and accents they use.
Customer service calls
Uzbek speech for models that route, transcribe or summarize customer calls about accounts, orders and claims.
Voice in the car and at home
An Uzbek base for in-car assistants and smart devices, before recording commands in the real setting.
Support and speech analytics
Uzbek conversations for models that find intent, sentiment or topics in support calls and chats.
Testing an Uzbek model
Held-back Uzbek recordings your model never trained on, to measure word and character error rate before launch.
How many hours of Uzbek 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 Uzbek 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 an Uzbek model from scratch | Thousands of hours | Stock as a base, plus a larger custom collection |
Free Uzbek speech datasets or a licensed one?
Public corpora such as the Uzbek Speech Corpus (USC), Mozilla Common Voice and FLEURS have done a lot for Uzbek 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 Uzbek corpora | Our Uzbek 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 an Uzbek speech sample
Half an hour with the Uzbek 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 |

Uzbek speech data terms
The words that come up when you buy or build Uzbek speech data. The full glossary covers every data type.
- Oʻ and gʻ
- Uzbek Latin letters written with a turned comma, often typed with an apostrophe instead.
- Agglutination
- Building words by adding suffixes in a chain, as Uzbek does.
- Karluk
- The branch of Turkic languages Uzbek and Uyghur belong to.
- 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, useful for Uzbek, where long suffixed words 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 Uzbek speech dataset
Straight answers about licensing Uzbek speech. The off-the-shelf FAQ covers questions that apply to every language.
Do you have an Uzbek speech dataset ready to license?
Yes. Roughly 500 hours of Uzbek speech, prompts and conversations are already recorded and ready to license, as part of our off-the-shelf speech pool.
What's in the Uzbek speech dataset?
A mix of scripted prompts and natural conversations in Uzbek, 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.
Are the Uzbek transcripts in Latin or Cyrillic?
Ask for the transcript script on the spec sheet. You can check it against your pipeline before you license.
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 Uzbek 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 Uzbek 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 Uzbek samples first?
Yes. Ask and we send Uzbek 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. Uzbek 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 an Uzbek 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 Uzbek 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 an Uzbek speech-to-text (ASR) dataset?
Yes. Every recording comes with a transcript, so it's ready for training and testing Uzbek 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 Uzbek speech dataset?
Public Uzbek 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 Uzbek speech dataset is roughly 500 hours.
How many hours of Uzbek 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 Uzbek 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.
