No consent capture or speaker verification, and the terms say so.\n\n**VoiceStudio.** Local audio generation with HTTP and MCP access. Hardware and model licences vary by backend.\n\n## Before you call either\n\n### Soniox Voice Cloning\n\n1. Poll the voice until the target model's status is `ready` before using it in TTS\n2. On `voice_not_prepared` call recompute, don't retry the TTS request\n3. Don't retry `voice_failed` even though it's a 503. Create a new voice from a better clip\n4. Use a key from the project that owns the voice, voices are per project\n5. Keep the clip under 2 minutes and 35 MB, longer fails with `voice_audio_too_long`\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- [Prepare a project voice for Soniox TTS](https://www.anchorterminal.com/tutorials/soniox-voice-cloning/), for Soniox Voice Cloning\n\n## Questions\n\n### Which is better for AI agents, Soniox Voice Cloning or VoiceStudio?\n\nSoniox Voice Cloning scores 58.6 (C) on agent readiness against VoiceStudio's 46.2 (D), and leads in 5 of 7 scored categories.
