## 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.

**VoiceStudio.** Local audio generation with HTTP and MCP access. Hardware and model licences vary by backend.

## 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

### VoiceStudio

1. Keep the server on loopback unless network authentication has been verified.
2. Use file outputs for large audio and restrict the output directory.
3. Check the selected model licence before commercial voice use.
