# VoxCeleb2 dev speaker names

Maps each of the 5,994 VoxCeleb2 dev speaker ids (`id00012`...`id09272`) to a
celebrity name with a confidence grade and the evidence behind it.

## Provenance

Two independent routes, cross-checked:

- **YouTube titles** (`youtube-title` source): titles of the first two YouTube
  videos per speaker, fetched via the YouTube oEmbed API, with names extracted
  and graded per title; a reserved third video was fetched only to adjudicate
  conflicts.
- **VGGFace2 identity_meta** (`vggface2` source): the authoritative
  VGGFace2 `identity_meta.csv` names joined to VoxCeleb2 ids via
  `vox2_meta.csv` (VoxCeleb2 identities are a subset of VGGFace2).

Route agreement over the 5,994 speakers: **agree = 4,691**, **conflict = 137**,
**vgg_only = 1,166** (VGGFace2 name, titles gave no usable evidence),
**yt_only = 0**, **unresolved = 0**. 69 of the 137 conflicts were manually
adjudicated with third-video evidence (source `adjudication`); the remaining 68
stay unnamed. A 40-speaker random spot-check found 37/40 fully consistent; the
3 flagged speakers (id00783 interviewer-vs-guest risk, id03812 own-channel
inference only, id07169 first-name-only title) are downgraded to `low`.

## Records

`voxceleb2_names_full.json`: `{"idXXXXX": {"name": str|null, "confidence":
"high"|"medium"|"low", "sources": [...], "evidence": str}}`.

- `high` — both routes agree, or adjudicated with strong third-video evidence
  (4,720 speakers)
- `medium` — VGGFace2-only, authoritative but title-unconfirmed (1,166)
- `low` — adjudicated on weaker evidence or spot-check-flagged (26 named);
  82 speakers remain `name: null` (68 unadjudicated conflicts, 14 adjudicated
  to null)

Coverage: **5,912 / 5,994 speakers named (98.6%)**.

Consumed by [voxpath](https://github.com/DJRHails/voxpath) as the committed

attached to corpus per-speaker metadata.
