If you play blitz on KGS, how do you cope with the absence of voice countdown?

I saw some high dan players make their moves at the last second, and I have no idea how they manage to do that so consistently.
I usually set the beeps to three or four seconds and try to make my move as soon as the beeps start.
But I find this a lot more stressful than the countdown.

Yes, voice countdown is a must - like on wbaduk server.
