Prompt-to-voice and nine new GPT-Live voices
Released prompt-to-voice for all API customers. Create a custom voice from a text description through the API or voice Playground, then reuse it in GPT‑Live sessions. Creating a prompt-generated voice is free; speech generation uses regular GPT‑Live session billing.
Added nine natural voices for GPT‑Live: Nuri, Juni, and Flitz (German); Brise and Sillage (French); Nira (Hindi); Harema and Shida (Japanese); and Noeul (Korean).
