Fortnite Sprachat?

I have been playing fortnite since session 1 and I have never had a problem, only now when I play trio, teams people never have a headset or don't speak but my girlfriend goes into a game and people talk directly and there's also the microphone that has a headset connected as soon as possible she comes into my lobby is no longer because the vocabulary is on that is due to the settings that I may have just do not know what to do

It may be because of the attitudes. Can you speak correctly so that the others understand you?

If you can't talk you have to go to the menu and there you can (at the bottom) set the open microphone and push to talk.

For me it is sometimes the same, but for me the mates are the ones who have the problem.
