Seven of the nation's top book publishers sued Amazon subsidiary Audible on Friday, asking federal courts to block the company from releasing a new feature called Audible Captions that's due out next month. 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.
This would be a slam-dunk argument if Audible were generating PDFs of entire books and distributing them to customers alongside the audio files. But what Audible is actually doing is subtly different—in a way that could provide the company with firm legal ground to stand on.
