Code:

local PLUGIN = PLUGIN;

-- Called when a player's typing display has started.
function PLUGIN:PlayerStartTypingDisplay(player, code)
    if (player:HasItemByID("handheld_radio") and !player:IsNoClipping()) then
        if (code == "r") then
            if (!player.typingBeep) then
                player.typingBeep = true;
              
                player:EmitSound("npc/overwatch/radiovoice/on1.wav");
            end;
        end;
    end;
end;

-- Called when a player's typing display has finished.
function PLUGIN:PlayerFinishTypingDisplay(player, textTyped)
    if (player:HasItemByID("handheld_radio") and textTyped) then
        if (player.typingBeep) then
            player:EmitSound("npc/overwatch/radiovoice/off4.wav");
        end;
    end;
  
    player.typingBeep = nil;
end;
