Yep, read "Even though studies suggest that a continued use of closed captioning will not only make your brain accustomed to them but will also improve your literacy rate," that. It impressed and is good you are finding it useful. I just get away now with volume up, for most movies. It seems on some they purposely do something to the audio, my feeling is could be to make male voices, particularly, huskier. That's likely all wrong. Seems almost like a tiny echo, or something. Sometimes i just leave the movie.
I hit a wrong button the other day and got an audio describing all background noises which the article said closed caption does in print. Tolerated it for a time before finally finding the button to turn it off again, so maybe i have closed caption on my tv too. Will have a look.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
