## What's in the Romanian speech dataset?

The IndecalAI OTS Romanian speech dataset is roughly 500 hours of Romanian speech, prompts and conversations, recorded by Romanian 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.

Romania is a growing hub for customer service centers and tech in Europe, and Romanian speech data is scarce compared with bigger languages. That makes licensed Romanian 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? Romanian speakers from our 30,000+ network record new speech to your brief, and our [Romanian data page](https://indecalai.com/datasets/languages/romanian.html) covers what we collect to order.

- ~30,000 minutes
- ~1.8M seconds of audio
- ~21 days, played back to back

## Romanian at a glance, for speech teams

The facts that shape a Romanian speech project, from who speaks it to how it's written. Our [Romanian data page](https://indecalai.com/datasets/languages/romanian.html) covers what we collect to order.

- **Status**: Official language. Official in Romania and Moldova, and one of the official languages of the European Union.
- **Where it's spoken**: Romania and Moldova. Spoken in Romania and Moldova, with large communities in Italy, Spain and Germany.
- **Script**: Latin alphabet. Written left to right, with ă, â, î, ș and ț.
- **Family**: Romance. An Eastern Romance language, with Slavic loanwords.
- **Varieties**: Regional accents. Speech from Muntenia, Moldavia, Transylvania and Moldova differs in sounds and words.
- **Codes**: ro · ron. ISO 639-1 and ISO 639-3 codes. Locales speech APIs often use: ro-RO, ro-MD.

## Romanian speech dataset, voice dataset or speech corpus?

Speech dataset, voice dataset, corpus: the names overlap. Here's how they differ, and where our Romanian data sits.

- **Romanian speech dataset**: The general term. Recorded Romanian speech with details about each recording, for training and testing speech models. The name this page uses.
- **Romanian 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.
- **Romanian audio dataset**: A wider term. It can include music or background sound. Ours is speech audio: Romanian speech, prompts and conversations.
- **Romanian speech corpus**: The research name. A structured collection of recordings and their details. Commercial datasets are corpora too, licensed instead of published.
- **Romanian ASR or speech-to-text dataset**: Speech plus what was said. For training a model that turns Romanian audio into text. Every recording in our Romanian dataset comes with a transcript.
- **Moldovan speech data**: Same language. The language of Moldova is Romanian. Ask whether the hours you license include speakers from Moldova.

## What makes Romanian hard for speech recognition

Where Romanian speech recognition usually goes wrong, and how to spot it in a sample before you buy.

### English words inside Romanian

Romanian speakers mix in English for tech and work. A model trained only on formal Romanian stumbles on that, so listen for it in a sample.

### Romanian letters

Romanian letters like ș and ț are often typed without marks, or with the wrong cedilla form. Check that the transcripts use the correct letters.

### Accents across Romanian speakers

Bucharest, Moldavian, Transylvanian and Moldovan speech carry different sounds and words. Check that the speaker mix covers your users.

### Articles at the end of words

Romanian attaches the article to the end of a word, like om and omul, so endings carry meaning a model has to hear.

## What teams build with a Romanian speech dataset

The projects Romanian speech data usually ends up in. They describe the work, not who it was for.

### Romanian speech recognition

Train or fine-tune a Romanian speech-to-text model, or adapt a multilingual model so it handles Romanian well. See: [Transcription](https://indecalai.com/services/transcription.html)

### Voice bots and IVR

Teach a voice bot how Romanian callers actually ask for things, in the words and accents they use. See: [Conversational AI data](https://indecalai.com/services/conversational-ai-data.html)

### Customer service calls

Romanian speech for models that route, transcribe or summarize customer calls about accounts, orders and claims. See: [Speech data](https://indecalai.com/speech-data.html)

### Voice in the car and at home

A Romanian base for in-car assistants and smart devices, before recording commands in the real setting. See: [Data collection](https://indecalai.com/services/data-collection.html)

### Support and speech analytics

Romanian conversations for models that find intent, sentiment or topics in support calls and chats. See: [Annotation and labeling](https://indecalai.com/services/data-annotation.html)

### Testing a Romanian model

Held-back Romanian recordings your model never trained on, to measure word and character error rate before launch. See: [Data and model evaluation](https://indecalai.com/services/model-evaluation.html)

## How many hours of Romanian 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 Romanian 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 Romanian model from scratch | Thousands of hours | Stock as a base, plus a larger custom collection |

## Free Romanian speech datasets or a licensed one?

Public corpora such as Mozilla Common Voice, FLEURS and research Romanian speech corpora have done a lot for Romanian 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 Romanian corpora | Our Romanian 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 Romanian speech sample

Half an hour with the Romanian 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 |

## Romanian speech data terms

The words that come up when you buy or build Romanian speech data. The full [glossary](https://indecalai.com/glossary.html) covers every data type.

- **Enclitic article**: An article attached to the end of a noun, as Romanian does with contul, the account.
- **Comma-below letters**: Romanian ș and ț, written with a comma below, often confused with the cedilla forms ş and ţ.
- **Moldovan**: The name sometimes used for Romanian as spoken in Moldova.
- **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 Romanian speech dataset

Straight answers about licensing Romanian speech. The [off-the-shelf FAQ](https://indecalai.com/datasets/ots/#faq) covers questions that apply to every language.

### Do you have a Romanian speech dataset ready to license?

Yes. Roughly 500 hours of Romanian speech, prompts and conversations are already recorded and ready to license, as part of our off-the-shelf speech pool.

### What's in the Romanian speech dataset?

A mix of scripted prompts and natural conversations in Romanian, 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.

### Does it include speakers from Moldova?

The speaker mix is listed on the spec sheet. Ask where the speakers in the hours you'd license come from, and the sample clips let you hear them before you commit.

### 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 Romanian 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 Romanian 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 Romanian samples first?

Yes. Ask and we send Romanian 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. Romanian 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 Romanian 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 Romanian 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 Romanian speech-to-text (ASR) dataset?

Yes. Every recording comes with a transcript, so it's ready for training and testing Romanian 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 Romanian speech dataset?

Public Romanian 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 Romanian speech dataset is roughly 500 hours.

### How many hours of Romanian 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 Romanian 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.
