Licence review

Preview registry disclosures. These source records do not establish permission for a complete model selection, its dependencies, or your use of a person's voice. A paid VoiceStudio licence covers the app's own code and does not replace upstream model or output terms.

Commercial model use: Not verified for this selectionCommercial output use: Not verified for this selectionModel redistribution: Not verified for this selection

Select a source below for its declared licence, revision, evidence and unresolved checks. An engine can offer several sources or variants; these records are not an installed-file manifest.

Registry 2026-10-09.draft1; evidence checked 2026-10-03. This is disclosure-only foundation work. It does not mean released apps enforce review before every download, and no real model workflow is verified ready by this snapshot. A local acknowledgement does not grant rights or complete a provider's own agreement or gated-access process.
