Abstract

An indexing scheme is created which correlates text to audio in a manner which allows the reader of an electronic book, magazine or other form of reading system may switch from reading text to listening to an audio version of the text in a seamless manner. A first index is generated prior to the storage of a text database. Preferably, this index attaches codes to words, sentences, and perhaps larger text segments such as paragraphs, pages, or chapters. A second index is created at the time of creation of the audio content. Again, codes are preferably created with respect to words and larger segments such as sentences, paragraphs, pages or chapters. The two indexes are synchronized as the material is presented to the user. Given that both the text and audio are preferably indexed in terms of words and larger portions of the material, differences between the recorded audio portion and the corresponding text are accommodated by finding the best match at the finest resolution.
