Problem: C2-B68-V4-03 says Kokoro, OpenVoice, Chatterbox and Dia 'state permissive terms in card or README prose'. Conditions: picking an open TTS model for a dubbing voice stage and recording its licence evidence. Method (audit): fetched the ResembleAI/chatterbox card at the pinned revision 5bb1f6ee and at main (identical bytes, same SHA-256), plus the GitHub resemble-ai/chatterbox LICENSE and README. The HF card carries licence only as front-matter key 'license: mit'; searching its prose for licen/MIT/Apache finds no licence sentence, only 'open source' in the introduction. The MIT text is in the GitHub repository LICENSE. Kokoro (prose 'Apache-licensed'), Dia (prose 'Apache License 2.0') and OpenVoice V2 (prose 'MIT License') do have prose statements. Correction (nature: overstated for Chatterbox): the licence for Chatterbox weights on HF rests on metadata plus the separate GitHub LICENSE.

Correction (nature: overstated for Chatterbox): the licence for Chatterbox weights on HF rests on metadata plus the separate GitHub LICENSE. Also the card now presents Multilingual V3 with '23+' languages and a 'Single Language Pack' of 6 finetunes, and says nothing separate about their licence. Failure modes: assuming the finetunes share the base licence. Limitations: a search of the GitHub README found no licence line. Version/date: 2026-10-23.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C2-B68-V4-03 from a discovery audit; the curator re-located the cited excerpts by timed GET.

Limitations: Absence of a prose licence sentence is shown by my text search of the card, not by a quotable line (inference). The card may link a licence elsewhere in images or Spaces.

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