The technology does exactly what it sounds like: display text captions on the screen of your phone or tablet as the corresponding words are read in the audio file. > The publishers argue that this is straight-up copyright infringement. In their view, the law gives them the right to control the distribution of their books in different formats. Audio is a different format from text, they reason, so Audible needs a separate license.
