## 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.

**Murf Voice Cloning API.** One sample of up to 30 seconds, ready in a few minutes. Enterprise only, with no self-serve or trial access.

## 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

### Murf Voice Cloning API

1. Expect 403 until Murf enables cloning for the workspace
2. Send a WAV, MP3 or FLAC at 24 kHz or above. A low sample rate is accepted and fails later
3. Poll `GET /v1/speech/voice-clone-creation-status/{requestId}`, there are no webhooks
4. Use clones only with Falcon 2 streaming. Gen2 or the non-streaming endpoint returns 400
