Voice Cloning
voice-clone-tts
Two ways to clone — persistent (async, reusable voice_id) and instant (sync, returns binary audio).
Persistent clone (core-voice-clone) is asynchronous: you get a 202 with a job_id, then poll /v2/jobs/{job_id} for the voice_id. Instant clone (core-instant-clone-tts) is synchronous and returns binary audio/wav with metadata in the response headers, or a JSON envelope with a hosted url when you send stream: false. Both accept audioUrl (camelCase) for the source sample (mp3/wav/ogg or a video — audio is extracted automatically).
Use upload-media to upload local audio/video and get a URL.
Persistent: cheapest per call when reusing the voice (one-time 1500 credits).
Instant: cheapest for one-off clips (4 credits/s, no one-time clone fee, raw audio response).
Cloning is provider-scoped — voice_id from elevenlabs cannot be used with minimax/openai.
