This extension is exactly what I needed. I needed something to read selected text off websites that I had a hard time reading, I tried the Windows 10 voice thing but it was so unruly and annoying - announcing everything my mouse went over when I just needed it to dictate selected text (Im not completely blind) - Windows failed. I found this extension and it does exactly that! Perfectly!
This should be a built in feature in browsers today, but thankfully we have this add-on extension.

After installing the add-on make sure you put a check next to the built in voices. Now I just need to find some better voices...
