Sinhala Read Speech Dataset
Sinhala Read Speech delivered to your specification. A catalog entry, not a stock listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why Read Speech in Sinhala is its own problem
The key question for Sinhala read speech is which text gets read. If the passage contains many English loanwords (common in written Sinhala), a speaker may read them with the English pronunciation or with a Sinhala-ized one, and that leaves the batch internally inconsistent.
The field to pin down first: The reading convention for loanwords has to be explicit, and loanwords should be marked in the text itself.

What Read Speech data is
Recordings of speakers reading specified text, with clear pronunciation and known text, the base material for TTS and ASR.
What buyers get wrong about it
The trap with read speech is that it is too clean. It comes out sounding like a news anchor, and a model trained on it underperforms in real conditions. We collect an extra set at natural speaking rate as a comparison.
The specification field that decides the quote
Studio (low noise floor) or home (real environment). The two differ in both signal-to-noise ratio and price.
The language side: what Sinhala demands
Everyday Sinhala conversation is heavily embedded with English words, especially in the Colombo urban belt. Treating this mixed speech as pure Sinhala strips out high-frequency loanwords as if they were errors.
What we can put in this delivery
-
Collection to your specification
Scripted or unscripted, in the language, domain and conditions your task needs. Specified separately where the variants need different contributor pools.
-
Labels to your convention
Orthographic, phonetic or categorical, with the guideline written before production and shared with you for review.
-
Contributor metadata
The attributes that let you slice the set rather than take it whole. The ones your task turns on, not a fixed list.
-
Consent documentation
Signed contributor 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
File format, structure, segmentation and metadata schema set to your pipeline's requirements.
What arrives in a delivery
| Component | What it is |
|---|---|
| The data files | Format, structure and segmentation set to your pipeline. Named to a convention you specify. |
| Labels or transcription | Orthographic, phonetic or categorical, produced under a guideline you review before production starts. |
| Contributor metadata | The attributes that let you slice the set: age band, gender, region, dialect background, or whatever your task turns on. |
| Collection conditions | Environment, device and, where it can be measured, signal quality: recorded per file. |
| Annotation guideline | The document the annotators worked from, so you can reproduce the conventions on your own data. |
| Consent records | Signed contributor consent covering your intended use, plus cross-border transfer terms where they apply. |
| Collection methodology | How contributors were recruited, screened and scheduled. The part that tells you how biased the pool is. |
| Quality report | Pilot outcome, re-work log, and the annotator agreement figures where the task supports measuring them. |
Questions we get about Sinhala Read Speech Dataset
How many distinct speakers can you provide for Sinhala Read Speech Dataset?
It depends on the specification and the timeline, and we will give a real number rather than a target. For this pairing, speaker recruitment is usually the step that sets the schedule. The reading convention for loanwords has to be explicit, and loanwords should be marked in the text itself.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. The key question for Sinhala read speech is which text gets read. That is exactly the kind of decision a default guideline leaves open, and it is where annotators diverge. Send us your guideline, or we will draft one and you can review it before production starts.
Do you offer a sample before we commit to a full run?
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 for Sinhala Read Speech Dataset before committing to the full volume.
Is the data licensed or owned outright?
Licensing terms are set per project, so tell us how the model will be used and whether it will be distributed. Consent documentation travels with the data either way, and we do not handle medical or clinical data or recorded telephone calls.
