Khmer Children Speech Dataset
Khmer children speech sourced to your specification — no inventory, no fixed listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why children speech in Khmer is its own problem
The difficulty in collecting Khmer children's speech comes from the writing system — if the task involves reading or writing, children's command of Khmer script varies widely, because Khmer orthography is complex and takes years to learn. Task design has to steer around literacy.
The field to pin down first: No task may depend on reading or writing — Khmer script takes years to master, and children's command of it varies far too widely to use as a screening criterion.

What children speech data is
Speech data from child speakers, grouped by age band, used for children's speech recognition and children's education products.
What buyers get wrong about it
Children's speech is the most compliance-sensitive category — a guardian must sign consent, and the collection process has to survive review. This is a hard requirement and cannot be skipped.
The specification field that decides the quote
Age banding (such as 3–5 / 6–8 / 9–12 years) and guardian consent documents must be included with every delivery.
The language side: what Khmer demands
Khmer script has no spaces between words, and it contains many letters that are written but not pronounced. The transcription convention has to be set first: write as spelled (orthographic) or write as spoken (phonemic). Data produced under the two conventions cannot be mixed.
What we can put in this delivery
-
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.
What arrives in a delivery
| Component | What it is |
|---|---|
| Audio files | Format, sampling rate and segmentation length set to your pipeline. Named to a convention you specify. |
| Transcription | Orthographic or phonetic, produced under a guideline you review before production starts. |
| Speaker metadata | Age band, gender, region and dialect background per file, plus a speaker identifier so the dataset can be sliced. |
| Recording conditions | Environment, device and, where relevant, measured signal-to-noise ratio per file. |
| Annotation guideline | The document the annotators worked from, so you can reproduce the conventions on your own data. |
| Consent records | Signed speaker consent covering your intended use, with the transfer mechanism addressed where required. |
| Collection methodology | How speakers 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 Khmer Children Speech
How many distinct speakers can you provide for Khmer Children Speech?
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. No task may depend on reading or writing — Khmer script takes years to master, and children's command of it varies far too widely to use as a screening criterion.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. The difficulty in collecting Khmer children's speech comes from the writing system — if the task involves reading or writing, children's command of Khmer script varies widely, because Khmer orthography is complex and takes years to learn. 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 Khmer Children Speech 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.
