NVIDIA/personaplex ? reverse-engineered prompt

I want to build a web app that I can run locally for having real-time, back-and-forth voice chats with an AI. It should feel like a natural conversation, meaning I can interrupt the AI and it can respond instantly without waiting for me to finish.

The most important feature is being able to control the AI's persona. I want a text input field where I can describe a role for it, like "You are a friendly teacher," or something more specific like "You work for a restaurant and your name is Owen." The AI needs to adopt that persona for our conversation. It should also support different voices. I'd like a way to select from a list of pre-set male and female voices for the AI to use.

The interface should be a simple web page. Use an open-source model from Hugging Face for the AI brain, maybe the one from NVIDIA called PersonaPlex.
