## What's in the Armenian speech dataset?

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

Armenian serves Armenia and a large, well-connected diaspora in the US, France and Russia. With its own alphabet and two standards, it needs speech data made for Armenian.

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? Armenian speakers from our 30,000+ network record new speech to your brief, and our [Armenian data page](https://indecalai.com/datasets/languages/armenian.html) covers what we collect to order.

## Armenian at a glance, for speech teams

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

- **Status**: Official language. Official in Armenia, with a large diaspora in Russia, the US, France and the Middle East.
- **Where it's spoken**: Armenia and the diaspora. Eastern Armenian in Armenia and Iran, Western Armenian across the diaspora.
- **Script**: Հայոց այբուբեն Armenian alphabet. Armenia's own alphabet, written left to right.
- **Family**: Armenian. Its own branch of the Indo-European family, with no close relatives.
- **Varieties**: Eastern and Western. Eastern and Western Armenian differ in sounds, grammar and spelling, enough to treat them separately.

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

The same Armenian data goes by several names, depending on who's asking. Here's what each name usually means.

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

## What makes Armenian hard for speech recognition

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

### Russian and English words in Armenian

Armenian speakers mix in Russian and English, especially in tech and business. A model trained only on formal Armenian stumbles on that, so listen for it in a sample.

### Armenian or Latin typing

Armenian has its own alphabet, but many people type it in Latin letters. Decide what your model should output, then check the transcripts.

### Accents across Armenian speakers

Yerevan, Gyumri, Iranian and diaspora Armenian carry different sounds. Check that the speaker mix covers the users you're building for.

### Eastern or Western

Eastern and Western Armenian swap some sounds, so the same written word is said differently. A model has to know which one it's hearing.

## What teams build with an Armenian speech dataset

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

### Armenian speech recognition

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

### Voice bots and IVR

Teach a voice bot how Armenian 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

Armenian 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

An Armenian 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

Armenian 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 an Armenian model

Held-back Armenian 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 Armenian 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 Armenian 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 Armenian model from scratch | Thousands of hours | Stock as a base, plus a larger custom collection |

## Free Armenian speech datasets or a licensed one?

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

Thirty minutes with the sample clips and the spec sheet tells you most of what you need. Use the same list on any vendor.

| 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 |

## Armenian speech data terms

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

- **Eastern Armenian**: The standard spoken in Armenia and Iran.
- **Western Armenian**: The standard spoken across the diaspora, with different sounds and grammar.
- **Armenian alphabet**: The 38-letter alphabet Armenian is written in, created in the 5th century.
- **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 Armenian speech dataset

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

### Do you have an Armenian speech dataset ready to license?

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

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

A mix of scripted prompts and natural conversations in Armenian, 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 it Eastern or Western Armenian?

Ask which standard is in the hours you'd license. The spec sheet lists the speaker mix, and the sample clips let you hear it 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 Armenian 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 Armenian 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 Armenian samples first?

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

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

Public Armenian 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 Armenian speech dataset is roughly 500 hours.

### How many hours of Armenian 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 Armenian 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.
