how to make an audio overlap itself?

not necessarily 100% related to scripting, however, i was making an rpg-like textbox that had text grunts play as each word scrolled on the screen. it sounds choppy when you play the singular sound over and over, so, is there a way to make it play over itself?

i've been told that i could make a new instance for it, but, would that need to be parented?

this is 100% client-side, if that's important.

local function textscroll(dialogue, voice)
	if indialogue == false then
		indialogue = true
		dialoguebox.Visible = true
		for i = 1, #dialogue do
			local letter = string.sub(dialogue, i, i)
			local nextletter = string.sub(dialogue, i + 1, i + 1)
			dialoguetxt.Text = string.sub(dialogue, 1, i)
			dialoguevoice:Play() --here's the sound that is being played. its choppy when it does play
			wait()
			if (letter == "," or letter == "." or letter == "!" or letter == "?") and nextletter ~= letter then
				wait(0.2)
			end
		end
	end
end
