## 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.

**Speechify API Voice Cloning.** Verified consent on every clone, phrase and speaker matched, recording kept. No cloning on the Free plan.

## 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`

### Speechify API Voice Cloning

1. Create the consent challenge only when the speaker is ready. It's single use and short-lived
2. Show the phrase as returned. Rewording it fails the match
3. Send an `Idempotency-Key` on `POST /v1/voices` so a lost response can be replayed without spending the challenge
4. Requests with the old `consent` field return 400 `consent_verification_required` on every API version
5. On 429 wait for `Retry-After`, then check `error.code` to tell a rate limit from a concurrency cap
