# Unified voice cloning API

> Voice cloning now has a single cross-model endpoint: POST /waves/v1/voice-cloning.

Voice cloning now has a single cross-model endpoint: `POST /waves/v1/voice-cloning`. Upload a short audio sample, get back a `voice_...` ID that works across supported Lightning TTS models.

The legacy Lightning-large clone endpoint is deprecated and will be removed in a future release.
