The era of open voice assistants has arrived
I tried years ago, I don't think I got it working, ended up using Rhasspy/voice2json instead (TIL: the creator of both is now the Voice Eng Lead for Home Assistant).
Looks like the GitHub is still somewhat active, although their roadmap links to a dead Trello: https://github.com/leon-ai/leon
- Leon is your open-source personal assistant who can live on your server

It's indeed suspicious. You're sending your voice samples, your various services accounts, your location and more private data to some proprietary black box in some public cloud. Sorry, but this is a privacy nightmare. It should be open source and self-hosted like Mycroft (https://mycroft.ai) or Leon (https://getleon.ai) to be trustworthy.
- Anything like ChatGPT that we can run ourself where we train with with our own data, so we can use it as personal assistant, where it only knows about oneself better than themselves ?
- open source AI projects
- Open alternative to Google Assistant/Siri/Alexa?

Voice Control was supposed to be the Future. Is Linux lagging behind?
I literally had this thought a couple of days ago and went down a small rabbit hole looking into it too! There's some stuff out there (I saw Mycroft and Coqui mentioned in the comments already, also check out Leon, Jarvis, and OA although not sure they all deploy to Linux) but ultimately, I just don't think the tech is there yet.

What if a DAO bought Alexa from Amazon?
Mycroft is pretty decent and there are a few other similar open source projects if you're interested (https://github.com/MycroftAI, https://github.com/leon-ai/leon)
-
Is there such a thing as a self-hosted Alexa that runs on a server, and has low power devices like an Amazon Alexa subscribe to that service?
Take a look at Leon I'm not sure it's what you're looking for but it look pretty awesome.
