This worked wonderfully! Thank you!

I see people had trouble getting this to work - If you try this, or you cant get it to work, remember that you have to scroll down to the description of the video and check the box of the subtitles you want read out-loud.

Example: If the video I'm watching features a Korean speaker but has subtitles written in English that I want read out-loud, I would check the 'English' box under the video player: If the video with the Korean speaker has Korean subtitles that I want read in English, I would check the 'Korean' box and from the drop down menu next to it, I would select English (because I want them read in English, not Korean)
