Amazon's Kindle cave shows the power of publishers

Kindle 2’s experimental text-to-speech feature is legal: no copy is made, no derivative work is created, and no performance is being given. . . . We believe text-to-speech will introduce new customers to the convenience of listening to books and thereby grow the professionally narrated audiobooks business.

Nevertheless, we strongly believe many rightsholders will be more comfortable with the text-to-speech feature if they are in the driver’s seat.

Therefore, we are modifying our systems so that rightsholders can decide on a title by title basis whether they want text-to-speech enabled or disabled for any particular title. We have already begun to work on the technical changes required to give authors and publishers that choice. With this new level of control, publishers and authors will be able to decide for themselves whether it is in their commercial interests to leave text-to-speech enabled. We believe many will decide that it is.
