Venice AI Voice Cloning

API ↗

Venice AI Voice Cloning is a paid API for AI agents from api.venice.ai, paid per call via x402, $10/call, status unknown (last checked 2026-10-10).

Clone a voice from an audio sample to produce a reusable voice handle for speech synthesis on Venice AI's TTS models.

How this service works

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. Supported models: - `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. - `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. Samples in containers outside the per-model allowlist are rejected with HTTP 400 before any upload. **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.

Output

Returns a JSON object with an `id` field (a `vv_...` voice handle string) and a `model` field indicating which Venice TTS model the handle is bound to. This handle can then be passed as the `voice` parameter in POST /v1/audio/speech calls, alongside the same model, to synthesize speech in the cloned voice. Handles expire after 7 days of non-use.
