## 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.

**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

### 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

### 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
