I switched to almost 100% Linux since 2020. And I've been popping in here every now and then since then to see if there's been any traction on adding a Linux client for this app. I kind of got used to using it with HCS packs for Elite Dangerous.
It would seem that major issue is Voice Attack's reliance on the built-in speech recognition in Windows. Some have gotten this to install and work in Linux, but not very well. It doesn't learn your speech so it's pretty limited and frustrating to use. And that's if you can get it installed and working at all....I haven't had any luck, but then without the speech learning ability, it's not really worth it.
I've found a few other speech to text apps that over the years that could work for entering keystrokes. But they've been mostly complex to use, and problematic.
I "just" found this open source app for speech to text in Linux, and it seem promising. Maybe the devs here can work it into a beta app for testing. But ya, I just found it so I haven't looking into it much yet. (

And it might be good to look into an alternative speech recognition app to use here in case Microsoft ever doesn't anything screwy with theirs. All of your eggs are in one basket so to speak.
In any case if I find anything promising I'll try to remember to pop over here and mention it.
PS: More and more people are moving to Linux these days. I've got my system running everything from old DOS games, to Win95 games, to XP and the newest. With ray tracing graphics, and such with little to no effort. It's just getting easier all the time. Especially with apps like Steam's Proton, and Lutris.
I guess you could call me a Windows guru. I've been working in computers since the mid 90's, and "almost" exclusively MS OS's. I know more about Widows in some cases than MS does. MS has even posted some of the solutions to issues I've found on their site. (They have good support people there, but there seem to be less and less of them every year.) But my point is that I know Windows. And I definitely feel that it will eventually be replaced by Linux. And this will be a good thing, for reasons I won't get into here. If you want to be future proof, you should be looking at expanding into Linux.
