## Verdicts

**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.

**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

### 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

### 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
