What are people hooking up to their HAVpe’s for good sounding speakers? Obviously Big brands like Bose kill it, but any cheap alternatives with good sound for whole house audio?

Nice, thanks for the link! I wasn’t aware of that. Sadly as with all shiny new things it doesn’t fit all my requirements… I’d really like to speak to my house in my native language. But I figure English will do. I’m gonna try that.
Not sure if an ESP32-S3 is fast enough for more advanced DSP plus the rest of an voice assistant. At least I found some ESP32 libraries with noise reduction, echo cancellation… There is the ESP-ADF and a project called ESP32-SpeexDSP. But I didn’t try that yet. The Rockckip / Luckfox development board looks nice as well. A Cortex-A7 and a few hundred megabytes of memory might come in handy. And whatever the NPU does. But I don’t have a clue what kind of software and libraries we got for embedded Linux or custom processing units.
Anyway. I think the production-grade stuff mostly uses multiple microphones and a combination of beamforming and echo cancellation. I got 4 inmp441 microphones here. But I lack the software/libraries to tinker with that kind of signal processing.
