Vietnamese Speech Commands Dataset
Vietnamese speech commands 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 speech commands in Vietnamese is its own problem
Vietnamese commands shift with the speaker's relationship to the listener (anh / em / chị), and in a voice assistant setting users usually take the neutral form, though older users bring honorifics in. If the word list does not cover that distribution, it fails on a specific slice of the population.
The field to pin down first: The word list has to state which speaker age bands it covers, and each age band needs enough speaker samples.

What speech commands data is
Targeted recordings of short command words or phrases, usually with many speakers reading each entry several times over, used for wake words and on-device command recognition.
What buyers get wrong about it
What buyers consistently underestimate is the repetition count — a single command entry needs at least a few dozen distinct speakers, each reading it multiple times, to cover pronunciation variation.
The specification field that decides the quote
Once the word list is locked it cannot change; adding words midway means starting a new batch.
The language side: what Vietnamese demands
Vietnamese has six tones, marked in writing by a heavy load of diacritics. The three major dialect regions — north, central, and south — realize tones quite differently, and mixing them in one batch gives the acoustic model contradictory tone cues.
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 Vietnamese Speech Commands
How many distinct speakers can you provide for Vietnamese Speech Commands?
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 word list has to state which speaker age bands it covers, and each age band needs enough speaker samples.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Vietnamese commands shift with the speaker's relationship to the listener (anh / em / chị), and in a voice assistant setting users usually take the neutral form, though older users bring honorifics in. 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 Vietnamese Speech Commands 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.
