SYNCHRONIZING PROGRESS IN AUDIO AND TEXT VERSIONS OF ELECTRONIC BOOKS

摘要

An electronic book system is configured to allow a user to listen to an audio version of an electronic book, then switch to reading a text version of the book on a different device, the text version being presented from the point where the audio version left off. One or more users can repeatedly switch from audio to text versions without losing track of their progress through the book. Correlation between audio and text versions is established by generating a correlation table or inserting position-related metadata in the audio or text data files.
