Welcome!!
Wow, that’s a VERY high point of entry that you set yourself up here!!
The answer to your question is YES, it can be done. It’s called HABbot.
For the microphones from different rooms, I don’t know, but it shouldn’t be too difficult.
Now, please read:
and follow the link at the bottom
You need to decide if openHAB is right for you
If yes, then install it. Follow the docs, not some video on youtube (Most are out of date)
Follow the docs to the letter. Step by step. Don’t miss one or don’t skip one because you think your know better, you don’t.
Once installed and running. Follow the tutorial. Again set-by step.
Copy the examples, DON’T COPY AND PASTE. Copy them, line by line, letter by letter. This way you’ll get to understand the code.
Good luck
