HOW TO MAKE IT SO PRESSING A BUTTON WHILE TYPING DOESNT ACTIVATE SCRIPT?

I want to make it so that when you press R while typing, the run script does not activate.

local Player = game.Players.LocalPlayer
local mouse = Player:GetMouse()
local origSpeed = 16
local character = Player.Character
local humanoid = character.Humanoid

game:GetService('UserInputService').InputBegan:Connect(function(input, process)
       if input.UserInputType == Enum.UserInputType.Keyboard then
           if input.KeyCode == Enum.KeyCode.R and Player and character and humanoid.WalkSpeed == origSpeed  then
        Player.Character.RUNSCRIPT.SPEED.Disabled = false
Player.Character.Anima.Disabled = true
Player.Character.RUNANIMATION.Disabled = false

        elseif input.KeyCode == Enum.KeyCode.R and humanoid.WalkSpeed == Player.Character.RUNSCRIPT.RunSpeed.Value then
         humanoid.WalkSpeed = origSpeed
       Player.Character.RUNSCRIPT.SPEED.Disabled = true
    Player.Character.RUNANIMATION.Disabled = true
Player.Character.Anima.Disabled = false
        end
    end
    end)
