Tamil speech dataset
We source Tamil speech data to order — speaker recruitment, recording, transcription and annotation, delivered with the consent documentation that makes the dataset usable rather than merely delivered.
What makes Tamil hard to collect
Written and spoken Tamil are two separate systems, and colloquial speech drops or merges a large share of sounds. Accents also differ across Tamil Nadu in India, Sri Lanka, and Malaysia, so speaker region has to be annotated on every record.
This is the part that cannot be templated. Every language has a specific failure mode, and a project that does not plan for it produces data that looks complete and trains badly.

What we deliver for Tamil
-
Read and conversational speech
Scripted recording for TTS, and unscripted conversation for recognition. Specified separately because they need different speaker pools.
-
Transcription to your convention
Orthographic or phonetic, with the guideline written before production and shared with you for review.
-
Speaker metadata
Age band, gender, region and dialect background per file, so you can slice the dataset rather than take it whole.
-
Consent documentation
Signed speaker consent covering the intended use, plus collection methodology and the annotation guideline.
-
Pilot batch
A small batch first, which you can reject. Misalignments surface after a few hours rather than at delivery.
-
Delivery in your format
Audio format, sampling rate, segmentation length and metadata schema set to your pipeline's requirements.

Questions we get about Tamil
How many distinct speakers can you provide for Tamil?
It depends on the specification and the timeline, and we will give a real number rather than a target. Speaker recruitment is usually the step that sets the schedule for Tamil, so the answer to this question is also the answer to how long the project takes.
Can you annotate to a custom guideline?
Yes, and for Tamil we would recommend it. The default conventions for this language leave several decisions open, and those decisions are exactly where annotators diverge. Send us your guideline, or we will draft one and you can review it before production.
Do you offer a sample before we commit?
Yes. Select a free sample in the request form and describe what you need. A pilot batch is the cheapest way to establish whether the quality bar is reachable before committing to a full run.
What if Tamil is not something you can source?
Then we will tell you rather than take the order. We would rather decline a project than deliver something that does not meet the specification.
Request Tamil speech data
Tell us the language, the hours, and what the data needs to look like. You will get a real number and a real timeline — not a range. If we cannot source it well, we will tell you that instead.
- Pilot batch before the full run, so problems surface early.
- Consent documentation delivered with the data.
- No medical or clinical data. No recorded telephone calls.
