Vietnamese Short Video Speech Dataset
Vietnamese short video 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 short video speech in Vietnamese is its own problem
Northern and southern Vietnamese creators have visibly different styles, and at fast speaking rates tone realization compresses — the pitch range narrows. Tone models trained on this data have to account for that, so the annotation needs to preserve actual pitch values rather than standard ones.
The field to pin down first: Annotate tones as actually produced, without normalizing to standard pitch values, and note how speaking rate affects pitch values.

What short video speech data is
Speech in the talking-head style of short video — fast, emotionally strong, colloquial — used for short video subtitles and content understanding.
What buyers get wrong about it
Short video speech spans a wide range of pace and emotion, and usually carries background music. To train a model for it, the data has to contain samples that are just as unruly.
The specification field that decides the quote
Whether background music is kept or removed directly affects what this data can be used for.
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 Short Video Speech
How many distinct speakers can you provide for Vietnamese Short Video 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. Annotate tones as actually produced, without normalizing to standard pitch values, and note how speaking rate affects pitch values.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Northern and southern Vietnamese creators have visibly different styles, and at fast speaking rates tone realization compresses — the pitch range narrows. 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 Short Video 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.
