OpenAI releases prompt-to-voice and nine new GPT-Live voices for API customers

OpenAI says prompt-to-voice is now available to all API customers, letting users create a custom voice from a text description through the API or voice Playground.

Custom voices can be reused in GPT-Live sessions, and creating one is free, while speech generation is billed at regular GPT-Live session rates.

OpenAI also added nine voices: Nuri, Juni, and Flitz in German, Brise and Sillage in French, Nira in Hindi, Harema and Shida in Japanese, and Noeul in Korean.
