Phasmophobia is a game about cooperation, to work together as paranormal detectives to find out what ghost is causing the haunting, and how to stop it! Talking is a massive part of teamwork, as communication is key to success, but if Voice Chat isn't currently working for some users, the probability of success slowly dwindles to death. Imagine if you were put in charge of the cameras, and you had to notify your friend of strange occurrences happening in a certain room, but alas, you can't because Voice Chat is down. If you have any problems with Voice Chat not working in Phasmophobia, try out the temporary fixes in this guide!
Phasmophobia Voice Chat Bug
Update: It seems that the fix down about Windows 7 and Cortana below was debunked by a lot of the comments of this article! If you are playing on PC, Cortana does not affect if Phasmophobia voice chat works, and you can happily play using Windows 7.
I've been having issues myself and what worked for me was, getting everyone I was playing with to restart Phasmophobia at the same time, then joining a lobby straight away. If someone joins a game after you've played a few games, you probably won't be able to hear each other. It's worth a couple of minutes to test if this works.
I also enabled Speech Recognition in the Windows settings and made sure that my microphone was the default mic. I ignored Cortana as she's always been disabled.
The beta update did work for me, but no one could not speak to the Ghost, no matter how much we baited it. We then disabled the beta, and all restarted at the same time. We could all hear each other instantly, AND the ghost could hear us when we began playing.
End of Update.
Before all else, check the in-game voice test to ensure your microphone is working correctly. Go to the in-game options and click audio. Next to voice recognition, click on the test option, and it'll tell you to speak into the microphone; if it picks up your voice, then you should be golden.
If not, try loading up any program that can speak into, such as Skype, Steam, or Zoom; if your voice is noticed in any of those programs, then Phasmophobia is at fault. If no program is registering your voice, make sure that the microphone is being detected by Windows, or make sure the correct microphone has been selected.
If any other program is detecting your voice, then move onto this next step. Close down Phasmophobia, and open up the Steam Library. Right-click on Phasmophobia, and navigate to properties. Under the Betas tab, select "beta-Unstable build" from the dropdown menu that appears. Close the window, and Steam should begin preparing to download a beta version of the game, including a patch for the voice bug. It should work when you relaunch Phasmophobia.
We all know that alt-tabbing in games is a marvelous feature, but it can affect certain features in some games. Phasmophobia is one of them, so for the best possible results of fixing Voice Chat, try not to alt-tab at all when playing it.
According to Steam discussion another potential fix has been found, but if you play Phasmophobia on Windows 7, you might be displeased.
Don't know if this is relevant to you or your friends, but the game is incompatible with Windows 7 due to using Cortana for voice recognition. If any of you are using Windows 7, you won't be able to use voice chat, or hear others using it. Same if you've disabled Cortana from spying on you.
Apparently, Phasmophobia uses Windows 10 Cortana for the ghost to understand your speech and language; if you have it disabled, then this causes an issue in-game. Reenable Cortana, and your Voice Chat issues might be gone from Phasmophobia.
