PROBLEM TO BE SOLVED: To provide techniques for creating a mapping that maps locations in audio data (e.g., an audio book) to corresponding locations in text data (e.g., an e-book).SOLUTION: A mapping is used for bookmark switching where a bookmark established in one version (e.g., an electronic book) of a digital work is used to identify a corresponding location in another version (e.g., an audio book) of the digital work. Alternatively, the mapping is used to play audio that corresponds to text selected by a user. Alternatively, the mapping is used to automatically highlight text in response to audio that corresponds to the text being played. |
