I’d recommend looking at the Wyoming/Piper/Rhasspy system. There’s some really good minds working on it and it’s got a big community behind it already. It’s also plug and play with Home Assistant which is awesome. It’s the system I use and while I’m still fine tuning it for my use cases it’s already pretty great.
Most people don’t appreciate link posts without summaries of the content. I’m one of these people. I don’t like clicking links unless I know at least an idea of what’s on the other side of the link. Is it worth my time? Is it worth my attention? Providing summaries of linked content gives a start to the conversation and keeps us from turning this forum into a clickbait-filled platform.
I’m experimenting with the Music Assistant add-on but it seems to be early days for that project. Could be awesome though as it combines media libraries from services (e.g. YouTube music) and self-hosted things (e.g. Navidrome) and plugs them into the Home Assistant ecosystem.
