## 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.

**Resemble AI Voice Cloning API.** Rapid clones from 10 seconds of audio, ready in under a minute. Cloning API only on Business ($1,000 a month) and Enterprise.

## 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

### Resemble AI Voice Cloning API

1. Create the voice, upload recordings or pass `dataset_url`, then call `/build`. Nothing trains until you do
2. Set `callback_uri` rather than polling for `status` to reach `finished`
3. Expect a rapid clone. Since 2026-06-30 API-created voices default to rapid, and create-voice has no field to pick another type
4. Upgrade any voice on a pre-Ultra model before synthesis, since those voices can no longer generate audio
5. Check `success` in every response body, log the request ID, and stay under 40 requests a second per token with your own backoff
