Like punisher said, you can disable voice emotes ingame by tapping Q-M-V and enable it anytime by pressing those buttons.
The emote spam is annoying and us admins are trying to get people to stop endlessly spamming emotes. Don't worry, the novelty of the emotes will wear off pretty soon. We had the same problem when the last emotes were added.
Just ask people not to spam emotes and if they don't listen, ask an admin to intervene. Or just turn it off with Q - M - V, although i'd prefer you don't, because some players try to use the emotes for tactics and teamplay. It's nice if you can hear me (or some other guy) shouting 'FALL BACK' so you know when to retreat a bit, for example.
I try to also type the commands, but in the heat of battle that is often hard. And i have only LEFT, RIGHT and CHARGE macro'd.
