Show HN: Real-time AI voice chat with Santa

I'm a co-founder at Fixie, a Seattle-based AI startup. We're launching an experiment to showcase what's possible with Fixie's real-time LLM-powered voice platform. You can check it out at https://hisanta.ai - you can have live voice chats with Santa, Mrs. Claus, Rudolph, and other friends (toggle the naughty/nice switch at the top for some other characters!)

We'd love to get your help testing this and get any feedback -- especially from people with kids :-)

All the code for this app is open source: https://github.com/fixie-ai/hisanta.ai

This is not just a thin wrapper around LLMs. To get the performance to this level, we've had to do a lot of engineering to wire together ASR, LLMs, and TTS models efficiently, and are doing some clever things to hide latency. Happy to answer any questions about the technology.

The Fixie platform (https://fixie.ai) powers the app and embeds the logic for managing voice sessions with LLM agents, which can be built either through a no-code UI or using our AI.JSX (https://ai-jsx.com) framework for building LLM apps. We support a range of ASR and TTS models under the hood as well.

We'd love your feedback! Drop me a line or join our Discord: https://discord.com/invite/tRMV7PW8f2

Thanks! Matt on behalf of the Fixie team

After discussing with my sister-in-law, though, we won't be showing this to my nephew -- still a true believer in Father Christmas -- because she reckons it sounds slightly too generated, and she's concerned that it might break the spell. :-(

For myself, I think I would have been charmed, but perhaps I was more of an 8-bit kid.
