Create the voice, upload recordings or pass `dataset_url`, then call `/build`. Nothing trains until you do\n2. Set `callback_uri` rather than polling for `status` to reach `finished`\n3. Expect a rapid clone. Since 2026-06-30 API-created voices default to rapid, and create-voice has no field to pick another type\n4. Upgrade any voice on a pre-Ultra model before synthesis, since those voices can no longer generate audio\n5. Check `success` in every response body, log the request ID, and stay under 40 requests a second per token with your own backoff\n\n### Ultravox Voice Cloning\n\n1. Send a single clean, single-speaker MP3 or WAV of 30 to 60 seconds, 10 MB at most\n2. Expect one clone per account unless support raises it, whatever the plan page says\n3. Test the voice in the Playground before putting it on a live agent\n4.
