Hardware and model licences vary by backend.\n\n## Before you call either\n\n### Speechify API Voice Cloning\n\n1. Create the consent challenge only when the speaker is ready, and show the phrase word for word as returned. It's single use and short-lived, and rewording fails the match\n2. Send an `Idempotency-Key` on `POST /v1/voices` so a lost response can be replayed without spending the challenge\n3. List clones with `GET /v1/voices?type=personal` so the shared catalogue doesn't fill the context\n4. On 429 wait for `Retry-After`, then check `error.code` to tell a rate limit from a concurrency cap\n5. Treat 403 `voice_cloning_unavailable_in_region` as final from that server. It follows the caller's IP, and no key, plan or retry lifts it\n\n### VoiceStudio\n\n1. Keep the server on loopback unless network authentication has been verified.\n2. Use file outputs for large audio and restrict the output directory.\n3. Check the selected model licence before commercial voice use.\n\n## Tutorials\n\n- [Create a consent-verified voice with Speechify](https://www.anchorterminal.com/tutorials/speechify-voice-cloning/), for Speechify API Voice Cloning\n\n## Questions\n\n### Which is better for AI agents, Speechify API Voice Cloning or VoiceStudio?\n\nSpeechify API Voice Cloning scores 76.8 (BB) on agent readiness against VoiceStudio's 46.2 (D), and leads in 6 of 7 scored categories.
