Sometimes people get angry and yell at me because I didn’t react to some sounds like footsteps when enemies are sneaking up behind me. Then I explain to them that I’m deaf. They would say like “Oh wow” or “Jesus Christ”. Sometimes they get upset that I don’t use a microphone because I don’t speak, I use sign language to communicate in the real life.

If players are either unable to hear other players’ speech, or unable (due to either lack of vocal ability or suitable hardware) or simply prefer not to to communicate by speech, this can have an impact on multiplayer play, resulting in players being intentionally kicked out or excluded from games.

A matchmaking preference can help to avoid this issue, allowing both players who prefer to play without speech and players who prefer to play with speech to take part according to their own personal play style or ability.
