@laryllan @cassidy Not much to say - #homeassistant voice keeps evolving from a RPi to an ESP32, and now a cheap FOSS device with a decent DAC and on-chip activity detection and processing.

The protocol was Wyoming, but this evolved to #LinuxVoiceAssistant as part of #ESPhome (and can run on RPi now).
The back-end can be anonymised cloud (like #Mycroft was) or fully local of you reduce the models or have a big GPU (trades accuracy Vs silicon).
