I wish to make a preliminary statement: I don't know enough HTML 4.0, XML and CSS2 to establish if what I am going to ask is already possible at this stage of development of these languages. The problem is: fine synchronization between two different media, for example, text and audio. In particular, in the case of parallel presentation of a text and the human reading of the same text, to realize a fine indexing of both text and digital record in such a way to allow the reader/listener to jump from one medium to another and to read/listen the same information, with a approximation at least of a sentence. This has been realized, in demo version, with a modified HTML, by the European Copernicus-Digibook project, in form of a so called "hybrid book" for blind people. This structure combines the high quality of the digitalized human voice with flexibility of an hypertext. For example, the user can listen to the audio version of the text and to stop in a certain point of the record to jump to the parallel textual version to verify the spelling of a name. Another example, it is possible to search a certain string of characters in the textual version and to jump directly to the corresponding point of the audio version. This in addition to the obvious advantage of a navigation inside the hypertext and the direct pointing to the parallel audio version. Such a structure results very effective for blind people in both local and network applications. In particular, in the mentioned European project, it has been conceived as a new powerful form of talking book for the blind stored on a CD-ROM. I'd like to know if such a synchronization is possible with the new release of HTML. If not, this could be a suggestion for the future releases which (I hope) could be of interest of more in general and not only for blind people.
