How can I magnify/zoom the text I am reading in Voice Dream Reader?

While reading a book, a single finger tap anywhere on the screen will show the reading tools menu. In the upper right corner tap on the text settings button, the “Aa” icon to access the Visual Settings menu appear.

From there, you will be able to increase or decrease the text size with the slide bar or with the text size decrement and increment buttons, the “-“ and “+” icons.
