Is your feature request related to a problem? Please describe.
Swearing isn't allowed on my server. When someone is muted for swearing, they can just use voice chat to scream their lungs off.

Describe the solution you'd like
A /voicechat mute <player> [duration] [reason] command that will mute the user's voice for everyone on the server.

Describe alternatives you've considered
Banning the user

Muting is completely client side. You can revoke the talk permission from a player with the bukkit plugin.

How can I do that? Can't find a command for it.

Ohhhhh, permission, gotcha.
