Fortnite vocabulary not working?

I hear everyone, my headset is off and it works everywhere except for voice chat.

Have to look in the settings you have then turned off what should be on

I know I've checked several times

I know that! Lousy thing…

Go into the settings and have a look at push to talk and such

If that's not the case, check to see if there's any evidence that someone is in another language channel.
