Small amendment to a simple Windows app

A small amendment to a Windows app called Read-it.

I am a doctor and have had a free Windows app developed aimed at helping children with dyslexia to read. I have the source code.
This is what the app does.
1. If a child has difficulty reading any word on a Windows screen, they can just click on that single word and just that single word will be immediately read aloud.
2. This lets the child carry on reading without interruption enabling them to read with fluency and easily understand/enjoy reading the text.
A short video (15 seconds) which shows what the app does is attached.
This is the amendment I need.
In addition to reading a single word aloud when a single click is made,
I also need the app to read aloud a full sentence if a double-click is made anywhere within a sentence.
