Detecting Speech, Location and UserId for teleportation?

So I am making a teleport system for a few players in my game so that they can move around the map sufficiently. However, I want it so they must be touching a certain part called "Teleport1" which is located in game.Workspace.Teleports.Teleport1. However, the following script allows the players to teleport whenever they want regardless if they are touching a part or not because i'm unsure how to add the touch function into this code and then to register it when the player says the command.

local isAdmin = {[14946581] = true, [28433911] = true, [51013956] = true}

PC = script.Places.PotionClass
TC = script.Places.TransfigClass
Dor = script.Places.Dorm
Te = script.Places.Teams

A = script.Effect.A
B = script.Effect.B
C = script.Effect.C
D = script.Effect.D
E = A:Clone()
F = B:Clone()
G = C:Clone()
H = D:Clone()


function onChatted(message, player)
  if message:sub(1, 5):lower() == ("Floo/"):lower()and isAdmin[player.UserId] then
    for _, child in pairs(player.Character:GetChildren()) do
      if child:IsA("BasePart") then
        spawn(function()
        if message:sub(6):lower() == (PC.Value):lower() then

          local E2 = E:Clone()
          local F2 = F:Clone()
          local G2 = G:Clone()
          local H2 = H:Clone()

          E2.Parent = child
          F2.Parent = child
          G2.Parent = child
          H2.Parent = child

          wait(.5)

          player.Character.HumanoidRootPart.CFrame = (CFrame.new(PC.Location.Value))
          wait(1)
          E2:Remove()
          F2:Remove()
          G2:Remove()
          H2:Remove()



          --Transfig class--

        elseif     message:sub(6):lower() == (TC.Value):lower() then
          local E2 = E:Clone()
          local F2 = F:Clone()
          local G2 = G:Clone()
          local H2 = H:Clone()

          E2.Parent = child
          F2.Parent = child
          G2.Parent = child
          H2.Parent = child

          wait(.5)

          player.Character.HumanoidRootPart.CFrame = (CFrame.new(TC.Location.Value))
          wait(1)
          E2:Remove()
          F2:Remove()
          G2:Remove()
          H2:Remove()

          --Potion class--
        elseif     message:sub(6):lower() == (Dor.Value):lower() then
          local E2 = E:Clone()
          local F2 = F:Clone()
          local G2 = G:Clone()
          local H2 = H:Clone()

          E2.Parent = child
          F2.Parent = child
          G2.Parent = child
          H2.Parent = child

          wait(.5)

          player.Character.HumanoidRootPart.CFrame = (CFrame.new(Dor.Location.Value))
          wait(1)
          E2:Remove()
          F2:Remove()
          G2:Remove()
          H2:Remove()

          --Potion class--
        elseif     message:sub(6):lower() == (Te.Value):lower() then
          local E2 = E:Clone()
          local F2 = F:Clone()
          local G2 = G:Clone()
          local H2 = H:Clone()

          E2.Parent = child
          F2.Parent = child
          G2.Parent = child
          H2.Parent = child

          wait(.5)

          player.Character.HumanoidRootPart.CFrame = (CFrame.new(Te.Location.Value))
          wait(1)
          E2:Remove()
          F2:Remove()
          G2:Remove()
          H2:Remove()


        end
        end)
      else
      end
    end
  end
end


game.Players.PlayerAdded:connect(function(player)
player.Chatted:connect(function(message) onChatted(message, player) end)
end)

Anyone have any ideas?

Thank you.
