{"uid":"cap_Lph3oEY5jPF__VP7pInWW","slug":"venice-ai-voice-cloning-e03998d8","name":"Venice AI Voice Cloning","description":"Clone a voice from an audio sample. Returns a voice handle (`vv_...`) that can be passed to POST /v1/audio/speech as the `voice` parameter to synthesize speech in the cloned voice; the handle must be paired with the same `model` used to create it.\n\nSupported models:\n\n- `tts-chatterbox-hd` (Resemble AI) — accepts MP3, WAV, FLAC, and M4A samples. Zero-shot: no persistent voice template is derived; the reference audio is uploaded to a TTL’d storage object and re-read on each synthesis call. Handles expire automatically after 7 days.\n\n- `tts-minimax-speech-02-hd` (MiniMax) — accepts MP3 and WAV only. Persistent: the upstream provider derives a custom voice template that survives across synthesis calls. Auto-deleted after 7 days without use; each successful TTS request resets the window. Currently limited access — contact support@venice.ai if you need it enabled.\n\nSamples in containers outside the per-model allowlist are rejected with HTTP 400 before any upload.\n\n**Authentication:** This endpoint accepts either a Bearer API key or an `X-Sign-In-With-X` header for x402 wallet-based authentication. When using x402, a `402 Payment Required` response indicates insufficient balance and includes top-up instructions.","url":"https://api.venice.ai/api/v1/audio/voices?utm_source=zero.xyz","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"file":{"type":"string","format":"binary","description":"The voice sample audio file (multipart/form-data, field name \"file\").
