List Catalog Provider Model Voices

List platform voices available for a specific provider and model.

Returns a paginated list of voices from the platform catalog (system workspace) that declare support for the given model. A voice can appear under multiple models when its supported_models list includes more than one entry; voices with no supported models are excluded from all model listings.

Voices are restricted to the officially supported locales, judged against THIS model: a voice whose official locale lives only on a sibling model is not listed here, and supported_languages carries only official locales. A voice for which the provider supplied no authoritative locale data for this model is excluded too. The voice_count on the model card that links here counts the same population.

Each voice includes gender, age, accent, supported locales, and a short-lived presigned preview_url for the audio sample — do not cache these URLs across sessions. The response pagination.total field reflects the total match count for the provider/model pair.

For the workspace voice picker (which merges platform and workspace-scoped voices and supports favorite/similarity filtering), use GET /voices with ?provider= and ?model= query parameters instead.

Returns 404 if the provider or model is not recognized or is not available to your account.
