Notes

Open voice menu (F10) is also reachable from the Options menu. This is where you set your mic/speaker device, push-to-talk vs open mic, noise suppression, and HUD layout.
Host voice settings (F11) opens only for the lobby host, from the game-settings console. See Host Settings.
Push to talk (C) works when open-mic is off. Hold to transmit.
Team radio (V) is held to talk on your team channel (when team radio is enabled by the host and your role qualifies). Cycle (G) switches between channels you can use.
Refresh voice (F7) re-establishes your own voice connection if audio drops. Host refresh (F8) asks all clients to refresh.
