My DH is hard of hearing, and uses CC constantly. It drives me crazy, because daily it is wrong about 50% of the time. I'm constantly saying "that's not what they said", or "that word makes no sense". Also, if the word/name is thought to be offensive, or misinterpreted, it appears as XXXX. I've often thought that there should be rules/standards in place for CC use. He gets very frustrated sometimes, especially if the captioning sticks, or lags behind during the news/weather.
