ActionScript 2.0 :: Animate A Word Static Paragraph?

I�m working on a LMS course, and since this material contain a lot of explanations and examples and etc, I�m using a lot of paragraph text with explanations.My intention is to inside those paragraph text, animate some word�s with setTimeout, so when the sound is narrating that word it zoom in the specific word. What I�m using latelly and is give�n a lot of work.Creating a function that apply the zoom function effect to the word that I have to break out of the paragraph text and converted to a movieclip, this is the simple function:

ActionScript Code:
function contabilidade_1()
{
zoomColor(topico_3.contabilidade_1);
}

And later create the setTimeout to show, in the specific time:

ActionScript Code:
var pausa_1:Number = setTimeout(contabilidade_1, 4000);
