## Verdicts

**ElevenLabs Voice Cloning and Voice Design API.** Instant clones from 1 to 2 minutes of audio on the $6 Starter plan. Instant clones rely on an attestation, not a check.

**Hume Octave Voice Design and Cloning + MCP.** Voice design from a natural-language description, saved with one call. Cloning over the API is Enterprise-only.

## Before you call either

### ElevenLabs Voice Cloning and Voice Design API

1. Keep the source samples. A clone can't be downloaded and re-cloning sounds slightly different
2. Check `requires_verification` in the create response before using the voice ID
3. List your own clones with `GET /v2/voices?category=cloned` instead of paging the whole library
4. On `system_busy` retry with backoff. On `too_many_concurrent_requests` queue instead, the plan cap won't lift
5. PVC is asynchronous. Create, add samples, verify, train, then poll `fine_tuning_state`

### Hume Octave Voice Design and Cloning + MCP

1. Design with `POST /v0/tts` using an utterance `description` plus sample `text`, then save a `generation_id` with `POST /v0/tts/voices`
2. Request several generations and pick one. A saved voice can't be tuned afterwards
3. List your own voices with `GET /v0/tts/voices?provider=CUSTOM_VOICE`
4. Use `/v0/tts/file` or streaming rather than the JSON endpoint to keep base64 audio out of context
5. On E0811 back off and retry, the request was rate limited
