# List Catalog Provider Model Voices

GET https://api.onepin.ai/api/v1/providers/{provider}/models/{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.
