## Verdicts

**Fish Audio Voice Cloning API.** Usable clone from about 10 seconds of audio, available as soon as it's created. No consent or speaker verification in the API.

**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

### Fish Audio Voice Cloning API

1. Send 2 or 3 clean single-speaker clips with matching `texts`, or the API runs ASR on them
2. Pass the model `_id` as `reference_id` in TTS. Check `state` before relying on it
3. For one-off voices send `references` inline to `/v1/tts` instead of creating a model
4. Send the `model: voice-design-1` header on voice design calls
5. Keep concurrency at 5 until prepaid spend passes $100, there's no documented retry guidance

### 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
