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
