Indonesian Multilingual Speech Dataset
Indonesian multilingual 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 multilingual speech in Indonesian is its own problem
Indonesian and Malay are close enough to pass for each other but are treated as two separate languages, so in a multilingual project they contaminate one another — an annotator can easily label a Malay recording as Indonesian. Indonesian also carries Javanese and Sundanese mixed in, which makes the language boundary messier than it looks.
The field to pin down first: Provide decision rules and examples for telling Indonesian from Malay, and state whether local languages get their own labels.

What multilingual speech data is
Speech data covering multiple languages within one project, used for multilingual ASR, cross-lingual transfer, and language identification.
What buyers get wrong about it
The biggest risk in a multilingual project is uneven quality — annotation teams for different languages work to different standards, and once merged they drag each other down.
The specification field that decides the quote
Speaker count, hours, and recording conditions must be listed per language; a combined total does not cut it.
The language side: what Indonesian demands
In everyday speech, Indonesians mix in local languages (Javanese, Sundanese) and English loanwords heavily. Three language components inside a single sentence is normal, so word segmentation and annotation rules have to be fixed before collection begins.
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 Indonesian Multilingual Speech
How many distinct speakers can you provide for Indonesian Multilingual 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. Provide decision rules and examples for telling Indonesian from Malay, and state whether local languages get their own labels.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Indonesian and Malay are close enough to pass for each other but are treated as two separate languages, so in a multilingual project they contaminate one another — an annotator can easily label a Malay recording as Indonesian. 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 Indonesian Multilingual 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.
