Want to play Phasmophobia on a Linux desktop or Steam Deck? Well, it still doesn't yet work fully as the voice recognition isn't there but support for it is coming thanks to the Wine team.
On Steam you would use Proton (which is built from Wine) since it's a Windows game, but the problem is that Phasmophobia uses Windows-specific voice recognition which you can't replicate right now. Recently though, Wine development version 7.4 was released and the changelog noted some additions for speech recognition.
To give more info, World Wine News issue 414 went up titled "The Curious Case of Phasmophobia" and as it turns out, the work involved is to directly help this game (and as a bonus of course bring speech recognition to Wine / Proton) as it's a good popular game to test with.
With the work spearheaded by developer Bernhard Kölbl (with help from others), they've created the start of an implementation of the windows.media.speech libraries. To even get there though, many other parts of Wine needed improving or some things missing entirely like adding in new "boilerplate code" for the likes of the Universal Windows Platform (UWP) and Windows Runtime (WinRT). After that, they needed some speech recognition software, as it would be crazy to write their own, so they ended up with Vosk and got it working with Wine.
This is only the beginning they say so more patches and work is yet to come. Still, it might not be too long before the ghosts will hear your screams.
