Tamil data for AI training, collected to your brief

Tamil data from IndecalAI is collected or reviewed by a native Tamil speaker, not pulled from an existing archive. We work with speakers across South Asia, where the same request can sound different a few hundred kilometers away, matched to your brief and checked before delivery.

The short answer

What Tamil data can we produce?

Tamil data from IndecalAI is speech, text, conversational and translation data collected or reviewed by a Tamil speaker for your brief, not pulled from an existing archive.

The same request can sound and read differently a few hundred kilometers away across South Asia, so we ask which region or script variant you need before contributors start.

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 Tamil and another language.

For the wider Indian language picture beyond this one language, see Indian language data.

About the language

What to know about Tamil before you brief it

Tamil has a literary history of more than two thousand years and is still spoken by a large community across India, Sri Lanka, Singapore and Malaysia, where it holds official or recognized status in several places.

Formal written Tamil and everyday spoken Tamil differ enough to behave like two registers, so a corpus of news text will not prepare a model for a phone call. Sri Lankan Tamil and the speech of Chennai or Madurai also sound different. Tell us the country and region, and whether English words should be kept as spoken or translated, because Tamil speakers borrow freely in daily conversation.

Languages that sit close to Tamil in script, family or region: Malayalam data, Telugu data, Kannada data, Sinhala data, Hindi data and Burmese data.

Categories we build in Tamil: Tamil BFSI Call Center Speech Data, Tamil Healthcare Conversation Speech Data, Tamil BFSI Complaint Classification 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 Tamil data

Each links to the service that runs it, with its full scope and process.

Tamil speech data

Recorded speech in Tamil: calls, prompts and voice bot utterances, with the regional accent or script variant you specify, reviewed before delivery.

Tamil text data

Written Tamil: messages, reviews, tickets or chat logs, written or labeled by people who read it natively.

Tamil conversational data

Scripted or spontaneous Tamil dialogue for voice bots and support agents, built around the regional variety your users actually speak.

Tamil translation

Human-verified translation between Tamil and another language, including the regional script or transliteration your project needs.

Before we start

What to put in a Tamil brief

Four things worth deciding before contributors start, so the first sample already looks right.

Region or dialect

Tamil is spoken mainly in Tamil Nadu and Puducherry in India, northern and eastern Sri Lanka, Singapore and Malaysia. Worth naming in a brief: Chennai speech, Madurai and southern speech, Kongu (Coimbatore), Sri Lankan Tamil. Tell us the region or community you're targeting so contributors are matched to the right one.

Script or transliteration

Script for Tamil: Tamil script, 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.

How it works

From your brief to reviewed Tamil data

One named contact owns the project from scoping to the last file.

  1. Brief

    You tell us the data type, the Tamil variety or region and roughly how much you need.

  2. NDA and scope

    We sign an NDA before any data moves, then agree the scope with you.

  3. Free sample

    We produce a small sample free, so you can check it before you commit.

  4. Production

    Contributors from our network work in our own tools, to the brief you set.

  5. Review

    A review pass runs before anything is delivered.

  6. Delivery

    The data comes to you, or moves on to another service with us.

Where it's used

Where Tamil data ends up

Common jobs for Tamil data. They're examples of the work, not a client list.

Voice bots and IVR

Recorded Tamil prompts and calls teach a voice bot to recognize how people actually speak, not just how a script reads.

Speech data

Support chat and tickets

Everyday Tamil messages, written in the domain you work in, give a chat assistant real phrasing to learn from.

Text data

Content moderation and sentiment

Labeled Tamil posts, reviews and messages teach a model to read tone and intent correctly in this language.

Conversational data

Localizing a product

Translating prompts, UI copy and training data into Tamil so a product reads like it was written for that market, not machine-translated.

Translation

Off-the-shelf, or built to your brief

Off-the-shelf Tamil 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 Tamil: see the Tamil speech dataset. Here's how the two paths compare.

Glossary

Tamil data terms, in plain words

General definitions. They describe the field, not a claim about us.

Native speaker review
A pass by someone who grew up speaking the language, checking that phrasing, tone and spelling read naturally, not just correctly.
Regional variety
A version of a language tied to a place, which can differ in vocabulary, pronunciation or script from the variety spoken elsewhere.
Code-mixing
Switching between two languages within the same sentence or conversation, common in everyday speech in many multilingual regions.
Human-verified translation
A translation checked by a person, rather than machine output delivered as final, catching meaning a model alone would miss.
Off-the-shelf dataset
Data already collected and packaged before a buyer exists, sold as-is to whoever licenses it next, rather than produced for one specific brief.

FAQ

Questions about Tamil data

The datasets FAQ covers questions that apply across every category.

Do you support Tamil?

Yes. Tamil 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 Tamil data collected?

Yes. Roughly 500 hours of Tamil speech, prompts and conversations are already recorded and ready to license. The Tamil speech dataset page has the details, and anything it doesn't cover we collect to your brief.

Can you mix regional varieties of Tamil 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 Tamil?

Speech, text, conversational data and translation to or from Tamil. Image and video categories don't depend on language, so Tamil 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 Tamil?

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 Tamil 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 Tamil should I ask for?

Ask for the one your users actually speak. Tamil is spoken mainly in Tamil Nadu and Puducherry in India, northern and eastern Sri Lanka, Singapore and Malaysia, and the forms most worth naming in a brief are Chennai speech, Madurai and southern speech, Kongu (Coimbatore), Sri Lankan Tamil. If you are unsure, describe your users and where they live, and your named contact will help you decide before collection starts.

How is Tamil written, and does it matter for the data?

Tamil data uses Tamil script, 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.
