Linux Speech Recognition

[MattEqualsCoder]

I still need to do my own proofreading of the code here, but wanted to get a PR out there finally. The goal here was to create an application and nuget package that could be used as close as possible with the setup we had before. I basically created classes that mirrored what we had before for building grammar, then added a way to build that into C# System.Speech native grammar for Windows users.

For Linux users, this utilizes the PySpeechService application I created, which is a Python application that uses gRPC to communicate back and forth to tracker. For text to speech, this uses Piper and for speech recognition it uses Vosk.

• PySpeechService GitHub
• Python app documentation
• Grammar JSON documentation (This basically took the previous grammar builder we used and created a JSON format for it.)
• C# nuget Package documentation

Still have some things I want to do before merging in:

• Add SMZ3 documentation for Linux users
• Review and potentially clean up code
• Remove temp changes to the GitHub action
• Test on Fedora and clean Arch & Linux Mint installs to verify setup steps
• Create config PR for the speech replacements
• Probably need to clean up some warnings

If this is only available on Linux, maybe we should have a compiler symbol for this (if one isn't built-in already) and surrounding the code where it's used. Then we can avoid adding the dependency itself entirely on Windows if it'll never be used there anyway.

[MattEqualsCoder]

Well, it is used for the grammar construction even on Windows, but I could possibly pull that out into a separate project/repo so that just the actual services themselves can be done that way.

That being said, I do plan on making a Windows version just for possible testing for pronunciations if desired for Pink's streams. It's just a lower priority.

[MattEqualsCoder]

I split it out so that grammar building is in its on nuget package so that it could be used on Windows whereas the actual services be Linux only, and I marked all of the functions as Linux only for now until I get it built for Mac and/or Windows. However, I was having issues getting OS dependent compiler constants working for actually being able to make the built code different. Might give it another go.

[MattEqualsCoder]

Okay, I think I've got everything sorted out the best I can for right now. I want to do some end-to-end testing with SMZ3 on various OSes, and I want to do a bit of testing just to make sure this didn't break Windows at all. Once that's done, I think this is ready to merge in and have a new build created.

[MattEqualsCoder]

Okay, I think this one is about as done as it's going to be for now. I tested SMZ3 with it in Linux Mint, Fedora, and Arch. Also should have fixed the issue Pink ran into with items not being tracked together, and fixed a potential issue that might come up with two identical messages back to back.
