VigOn connector — speaker-embedding model (models/voxceleb_CAM++_LM.onnx)
=========================================================================

The voice artifact downloads, on the customer's machine, the WeSpeaker CAM++
speaker-embedding model trained on VoxCeleb (large-margin fine-tuned, "LM").
It is used unmodified, as published.

  Model:   Wespeaker/wespeaker-voxceleb-campplus-LM (Hugging Face)

Model weights
  The two upstream declarations disagree: the Hugging Face model card says
  Apache-2.0, while WeSpeaker's docs/pretrained.md says the pretrained models
  follow the licence of their dataset, and that VoxCeleb follows Creative
  Commons Attribution 4.0. The stricter one is applied: the weights are
  treated as licensed under CC BY 4.0,
  https://creativecommons.org/licenses/by/4.0/,
  and are attributed here to the WeSpeaker authors (wenet-e2e/wespeaker).
  No changes were made to the weights.

Training data

  The audio itself is NOT distributed; the model weights were trained on it.

Licence position
  The weights are shared unmodified. Under CC BY 4.0 that means: the
  attribution above (Section 3(a)), and no additional terms or technological
  measures that restrict the rights the licence grants (Section 2(a)(5)(B)).
  The ShareAlike term of CC BY-SA 4.0 applies only to adapted material that
  the one who shares it produces (Section 3(b)); VigOn produces none, so the
  same duties apply even if that term reached the weights.
  VigOn's terms of service do not restrict these rights: their clause 5.2
  leaves each open-licence component under its own licence.

Disclaimer of warranties
  As Section 5 of CC BY 4.0 states, the licensor offers the weights as-is and
  as-available, and makes no representations or warranties of any kind
  concerning them.
