Just replace the nozzle. You can try using the cleaning filament in the future, I use it when I'm swapping filaments -especially when I change between different types.
That highly depends on the language you’re using and therefore the model you’re going to settle on. If you’re using English you’re obviously lucky in that regard, but not everyone (including me) does.
I’m not sure what do you mean it’s not open source, because Micro Wake Word and Voice Assistant are. Check the link I’ve posted it has both source for the software and hardware design
None of them required many cloud specifically, but you have to provide it with STT and TTS engines. You can use other 3rd party or run it on your own hardware, but to do it effectively (have it transcribe your voice in a second instead of 20) you need a GPU.
I am using a few of self-built assistants using https://github.com/formatBCE/Koala-Satellite/tree/main - which was heavily inspired and uses a lot of very similar hardware to HA Voice. I have to say my speakers turned out pretty great.
