How to scale a certain part of a 2D Sprite?

Let's say there is a 2D Sprite with small paragraph. Text components are not added. They are in the 2D Sprite. So I want to highlight the words and sync with the audio. Like the "GILLIAN" word scaled below in the image below.

I tried following ways. 1. I tried using mask, but if I scale the masked sprite position does not syncs. 2. I tried magnifiers but I want to scale the each word from the sentences.

I searched a lot, didn't find any solutions.
