Project mention: I Open-Sourced My AI Toy Company That Runs on ESP32 and OpenAI Realtime API | news.ycombinator.com | 2025-04-22
This looks like so much fun! I have recently gotten into working with electronics, so it seems like a nice little project to undertake.
I noticed that it is dependent on openAIs realtime API, so it got me wondering what open alternatives there are.
I could only find ultravox (https://github.com/fixie-ai/ultravox) that would seem to really work as realtime. It seems to be some model that wires up llama and whisper somehow, rather than treating them as separate steps which is common with other projects,
What other options are available for this kind of real-time behaviour?

Project mention: Open source TTS by Resemble (claiming they are sota) | news.ycombinator.com | 2025-06-11It can definitely run on CPU — but I'm not sure if it can run on a machine without a GPU _entirely_.
To be honest, it uses a decently large amount of resources. If you had a GPU, you could expect about 4-5 gb memory usage. And given the optimizations for tensors on GPUs, I'm not sure how well thinks would work "CPU only".
If you try it, let me know. There are some "CPU" Docker builds in the repo you could look at for guidance.
If you want free TTS without using local resources, you could try edge-tts https://github.com/travisvn/openai-edge-tts
