Home Assistant [1] can be a voice assistant (both on phone and on dedicated devices). It's FOSS and can be fully local [2]. It's really gear towards home automation though, so its suitability depends on what you want to do with an assistant

[2] Although frankly to have a fast-enough and good-enough LLM you might need to use a service

I do want to setup home assistant at some point, but my main usecase for a smartphone assistant is what I mentioned. Things like setting reminders/todo list items, creating calendar events - even sending quick messages to contacts. Basically, things I can already do on my phone, but can do quicker through natural language.

I just have an always on VPN so can tunnel back to my home assistant server; which can handle todos/reminders/calendar events. Quick messages to contacts I haven't considered.

		I already use a VPN (Proton) so I can't VPN back to my home (i.e. Tailscale). A very unfortunate limitation of Android. RethinkDNS has the potential to solve all my problems since it can do per-app proxies, however I've found that it doesn't work well with Proton (or possibly Wireguard as a whole) with frequent proxy disconnects, making it a very painful experience. Which is a shame because in some cases I value DNS filtering more than VPN.

		Last time I tried, Android Auto refused to connect with an error message stating it will not start if VPN is active on the phone.

Yeah HA isn't the best choice. It can do some of that stuff, but will require lots of customization to do so. Plus I think you would find things it can't do at all.

Nobody wants to say “Hey Nabu” though ;) Including me (and I bought one of the things)
