Request
multipart/form-data body.
Reference audio. MP3, WAV, or M4A. Max 10 MB. Duration must be 10 seconds to 5 minutes — Kyma parses the audio header locally and rejects out-of-range files with
400 reference_too_short or 400 reference_too_long before charging. Longer clips don’t improve clone quality and waste upload bandwidth.Optional human-readable label, max 64 chars. Surfaced in the response and stored alongside the ownership row for your reference.

minimax-voice-clone is supported.Response
200 OK JSON.
X-Kyma-Model, X-Kyma-Cost-USD, and X-Kyma-Balance-USD headers are also set.
Pricing
Flat $2.10 per cloned voice. One-time charge — once cloned, thevoice_id is reusable in unlimited TTS calls.
Ownership
Cloned voice IDs are gated per Kyma user. If user A passes user B’svoice_id to /v1/audio/speech, the request returns 403 voice_not_owned. Voice IDs that aren’t on file are assumed to be MiniMax system voices (browseable by everyone).
