Spanish Spain OpenAI TTS models

Hi there,

I have just started with OpenAI because I want a realistic voice to read aloud some documents that I have on my disk. I have tried in english and is good, but with Spanish I have a problem that they are using Latin American accents on the tts model by default. I add to the prompt that they have to read it in Spanish from Spain but still there is a lot of Latin American accent of the speech.

Can anyone share their prompts on how to ask for ES-ES tts or only Latin American Spanish is developed on the models?
