# List PVC voices
> Lists Professional Voice Clones owned by the calling workspace, across every state (draft, queued, training, ready, and failed).
Returns PVC voices in every lifecycle state — draft, queued, training, ready, and failed — for the workspace resolved from your API key. There's no server-side `state` filter yet; filter the `state` field on the client if you only want, for example, ready voices.
Once a voice reaches `PVC_VOICE_STATE_READY` here, it's also returned alongside your other voices from [List voices](/api-reference/voiceAPI/voiceservice/list-voices) (`source = "PVC"`).
