Manipulating tables for an NPC-dialog GUI?

	local textPath = script.Parent
	local text = ""
    local textlen = string.len(text)

    for i = 1, textlen do
        textPath.Text = (string.sub(text, 1, i))
			script.Parent.Sound:Play()
            wait(0.04)
    end

I'm making a GUI that has a character 'speak' text, but I want the character to say the multiple sets of text in a single function without needing a messy script.

Basically, I want my local text variable to have a table containing different texts and manipulating said table to say certain phrases.

In this case, it's just going to be something like this:

local text = {
"T";
"E";
"S";
"T";
}

I need this manipulative variable to be intertwined into my current script, but I don't know how to. Also, if a kind gentleman/lady would tell me how to order how the text is "played-through", I would be greatful.

Ultimately, I'm asking for somebody to modify my script to the way I like it, I apologize if this sounds like a request; I have no real idea on how to do this.

function phrase1()
    local phrase = ("Hello.")
end

function phrase2()
    local phrase = ("How are you?")
end

local phrase = phrase1() --starts with phrase1

for i=1,string.len(phrase)do 
wait(0.1)
p.Text = string.sub(word,1,i)
end

phrase2() --convert to phrase two

for i=1,string.len(phrase)do 
wait(0.1)
p.Text = string.sub(word,1,i)
end

--rinse and repeat

function chat1()
	local word = ("Hello.")
	for i=1,string.len(word)do wait(0.1)
	p.Text = string.sub(word,1,i)
	end
end

The above script will take whatever your local word is, and then spell it out one letter at a time. Hope that's what you wanted.
