Where does the Chatterbox TTS licence appear: Hugging Face card prose, card metadata, or the GitHub repository?
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. Also the card now presents Multilingual V3 with '23+' languages and a 'Single Language Pack...

- [sourced_fact] 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. 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.
