Khmer In-the-Wild Speech Dataset
Khmer in-the-wild 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 in-the-wild speech in Khmer is its own problem
Khmer in-the-wild transcription has to deal with the mismatch between orthography and pronunciation, and when the audio is unclear it is even harder to judge which letter to write. Annotators need extra decision rules, or the transcription comes out inconsistent on a large scale.
The field to pin down first: The speaker's dialect origin has to be logged per file — urban Phnom Penh Khmer, rural varieties, and Khmer Krom or Surin speakers differ enough that pooling them unlabelled destroys the dialect signal.

What in-the-wild speech data is
Speech collected under fully natural conditions — no studio, no topic constraints — as close to real usage as collection gets.
What buyers get wrong about it
Real and usable pull against each other — the more natural the audio, the harder it is to annotate. The balance has to be designed into the collection plan, not patched in afterward.
The specification field that decides the quote
Recording device (phone, headset, professional mic) and collection environment must be logged per file.
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 In-the-Wild Speech
How many distinct speakers can you provide for Khmer In-the-Wild 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. The speaker's dialect origin has to be logged per file — urban Phnom Penh Khmer, rural varieties, and Khmer Krom or Surin speakers differ enough that pooling them unlabelled destroys the dialect signal.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Khmer in-the-wild transcription has to deal with the mismatch between orthography and pronunciation, and when the audio is unclear it is even harder to judge which letter to write. 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 In-the-Wild 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.
