Looking for advice to build an AI Speech NPC world in Horizon

Hi everyone,

I’m exploring the new NPC / AI Speech NPC features in Horizon Worlds. My idea is simple:

Create a world with an AI-powered avatar/character.
Enter through my Quest headset and be able to talk with it, getting real-time natural voice responses.

I’d love to learn from anyone who has already experimented with this:

What’s the workflow you used to set up AI NPCs?
How did you connect speech recognition and TTS (external APIs vs built-in)?
Any pitfalls I should know about (performance, scripting, UX)?

In addition to general advice, I’m also looking for a developer who has experience building Horizon Worlds and experimenting with AI NPCs to help me create this. If you’ve done similar work, please reach out—I’d be happy to chat more about collaborating.

Thanks in advance for any pointers!
