How do you do a part generator?

Hello, I am Decorpsesonator. I need help doing a voice activated part generator. For instance, this part generator will generate a map that I created by means of speaking/chatting it. I did a simple voice map cloner but it does not work. Please do help me in my problem. If you do reply fast, that would be magnificent. Thank you.

I'm guessing you already have the model, so I'm going to just put an example in for that.

model = WhereEverTheModelIs
modelc = model:Clone()
modelparent = model.Parent

function Chatted(msg, player)
	if player.Name = "YourUsername" then
		if string.lower(msg) == "msg that activates generator" then
			c = modelc:Clone()
			c.Parent = modelparent
			c:MakeJoints() -- may or may not be necessary
		end
	end
end

function PlayerAdded(player)
	player.Chatted:connect(function(msg) Chatted(msg, player) end)
end

game:GetService("Players").PlayerAdded:connect(PlayerAdded)
