Before you call either
ElevenLabs Voice Cloning and Voice Design API
- Keep the source samples. A clone can't be downloaded and re-cloning sounds slightly different
- Check
requires_verificationin the create response before using the voice ID - List your own clones with
GET /v2/voices?category=clonedinstead of paging the whole library - On
system_busyretry with backoff. Ontoo_many_concurrent_requestsqueue instead, the plan cap won't lift - PVC is asynchronous. Create, add samples, verify, train, then poll
fine_tuning_state
Hume Octave Voice Design and Cloning + MCP
- Design with
POST /v0/ttsusing an utterancedescriptionplus sampletext, then save ageneration_idwithPOST /v0/tts/voices - Request several generations and pick one. A saved voice can't be tuned afterwards
- List your own voices with
GET /v0/tts/voices?provider=CUSTOM_VOICE - Use
/v0/tts/fileor streaming rather than the JSON endpoint to keep base64 audio out of context - On E0811 back off and retry, the request was rate limited
