Sometimes the captions' letters on the TV are only about 25% of those in the actual dialog. They are correct but, run together and not all there. Is this because of insufficient voice recognition technology, a bad typist, or something else? It is program/movie specific and only occasionally, while other channels are fine. Also, I started using it to see occasional barely audible dialog of actors that were whispering, and found that the captioners/typists don't hear that dialog or type it either.
