GET/voices/cartesia

Cartesia Voices

The voice catalogue of the Cartesia text-to-speech service: active voices, filterable by language (ISO 639-1), gender and a search string. Put the voice_id from the response into tts_settings.voice_id of a template with service_key: cartesia; the voice_id parameter finds one voice by its exact id — the name of a voice already chosen in a template.

voices.read

Your own cloned voice does not show up in the catalogue — its voice_id comes from GET /voices/cartesia/clones (only once the clone is ready). A voice cloned outside Lumean (for example on cartesia.ai) is accepted too: put its Cartesia id (a UUID) into tts_settings.voice_id as is.

If the service is closed to the key owner (closed testing), the answer is 404 with reason: service_not_found.

Required key permission: voices.read.

Parameters

The inputs live inside the request line: fill in a value and you get a ready URL. Below are the type, whether it is required and the allowed values of every parameter.
