Simplest non-cloud voice recognition

I’m looking for a dumb but simple non-cloud voice assistant. I don’t care about intents, I only want to recognize exact phrases that I have pre-programmed.

I need microphones in at least 8 different rooms and Cat5 is available in all of them.

I’d appreciate your recommendations.

Cheers, Richard

I think there is only really Rhasspy for that.
If there is another solution, then the Rhasspy forum have the few persons that actually would know those, so try asking there.
