Idk if this covers your needs, but Home Assistant is non-cloud and supports voice commands. They're selling a voice hardware now (preview edition):https://www.home-assistant.io/voice-pe/While I've used HA for years, I've never tried any of the voice command methods, so can't really comment on it. I had just recently came across their voice hardware and am probably going to give it a try.
