# List Voices

> Returns all available TTS voices across configured providers.

<Note>
  Every endpoint on this page requires either a Clerk-issued JWT (`Authorization: Bearer <token>`) or
  an organization API key (`x-api-key: pk_…`). Anonymous calls return `401 Unauthorized`. See
  [Authentication](/authentication) for the full setup.
