POST
Render text in the voice of a supplied reference clip in a single call. Internally clones the reference and synthesizes the text in that voice — equivalent to chaining voice clone and T2A but without threading a voice_id between requests. Best for one-off “say this in this voice” interactions where the caller doesn’t need to persist the cloned voice for reuse.
