Vietnamese Singing Voice Dataset
Vietnamese Singing Voice delivered to your specification. A catalog entry, not a stock listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why Singing Voice in Vietnamese is its own problem
The six Vietnamese tones are overridden by melody in singing too, and northern and southern singers have different habits in Vietnamese pop (northern singers articulate closer to the standard pronunciation, southern singers more loosely). If accent origin is not labeled clearly, the acoustic features get mixed together.
The field to pin down first: Each singer's regional accent gets annotated record by record, and delivery is batched by accent.

What Singing Voice data is
Vocal recordings with melody, in both a cappella and accompanied form, used for singing voice synthesis, music information retrieval, and lyric alignment.
What buyers get wrong about it
Copyright is the number one problem for this category: melody and lyrics each have their own rights holder. We only produce original or fully cleared content, never existing commercial tracks.
The specification field that decides the quote
Whether the accompaniment is separated (dry vocal) or the mix is kept, and whether MIDI or pitch annotation comes with it.
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
-
Collection to your specification
Scripted or unscripted, in the language, domain and conditions your task needs. Specified separately where the variants need different contributor pools.
-
Labels to your convention
Orthographic, phonetic or categorical, with the guideline written before production and shared with you for review.
-
Contributor metadata
The attributes that let you slice the set rather than take it whole. The ones your task turns on, not a fixed list.
-
Consent documentation
Signed contributor 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
File format, structure, segmentation and metadata schema set to your pipeline's requirements.
What arrives in a delivery
| Component | What it is |
|---|---|
| The data files | Format, structure and segmentation set to your pipeline. Named to a convention you specify. |
| Labels or transcription | Orthographic, phonetic or categorical, produced under a guideline you review before production starts. |
| Contributor metadata | The attributes that let you slice the set: age band, gender, region, dialect background, or whatever your task turns on. |
| Collection conditions | Environment, device and, where it can be measured, signal quality: recorded per file. |
| Annotation guideline | The document the annotators worked from, so you can reproduce the conventions on your own data. |
| Consent records | Signed contributor consent covering your intended use, plus cross-border transfer terms where they apply. |
| Collection methodology | How contributors 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 Singing Voice Dataset
How many distinct speakers can you provide for Vietnamese Singing Voice Dataset?
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. Each singer's regional accent gets annotated record by record, and delivery is batched by accent.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. The six Vietnamese tones are overridden by melody in singing too, and northern and southern singers have different habits in Vietnamese pop (northern singers articulate closer to the standard pronunciation, southern singers more loosely). 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 Singing Voice Dataset 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.
