You’re in luck! 2023 is Home Assistant’s “year of voice” in which lots of development is being focused on a functional voice assistant that is run locally. Some links to what is available and what is in the works:

It’s a lot of DIY still as there still isn’t much of a market for voice assistant hardware that isn’t already part of an existing platform (Google home, Alexa, Sonos, Siri, etc). There is much more out there but these should get you started.

I keep meaning to deploy it but have yet to get around to it. It’s the only thing I’ve found that’s good for total local voice control and somewhat polished.

Check out their latest blog post. They are doing the year of voice, which is to do exactly this.

I’ll try dig up the link.
