LRS2 is offered for non-commercial academic research only after signing a BBC R&D Data Sharing agreement (agreement not read); LRS3 is described as available for research purposes under CC BY 4.0 while its licence file says the underlying TED video excerpts must respect TED terms and CC BY-NC-ND 4.0, copyright stays with the video owners, and downloads are no longer offered on the site. None of these texts mention model training.

Curator qualifications: How 'CC BY 4.0 for research purposes' combines with BY-NC-ND 4.0 source content is unresolved; treat LRS3 content as non-commercial, no-derivatives at the content layer. BBC agreement text not read. Page/licence text only; no data downloaded (LRS3 downloads withdrawn; LRS2 behind agreement). Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: Live academic pages. [component_reuse_restriction] Do not train, redistribute or modify LRS2/LRS3 media in Veyrul fixtures without rights review.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
