Apparatus and methods of revealing the hierarchical structure of a document having content of a characteristic type of content are described (). The hierarchical structure may be expressed, independently of document content type, as a tree structure of one or more nodes () A semantic representation for interpreting the tree structure may also be provided, document description files are used to encapsulate structural and meta information associated with a document stored on a computer-readable medium (). Document description files are external to native application files and have a set of required fields. Document description files point to the referenced document data using uniform resource locators (URLS) and serve as virtual documents. In addition to the required fields, applications can choose to encode additional structural information in the document description files.

Describing documents and expressing document structure

Document description files are used to encapsulate structural and meta information associated with a document stored on a computer-readable medium. Document description files are external to native application files and have a set of required fields. Document description files point to the referenced document data using Uniform Resource Locators (URLs) and serve as virtual documents. In addition to the required fields, applications can choose to encode additional structural information in the document description files.

Providing descriptions of documents through document description files

Methods and apparatus of processing, storing and transmitting an original data stream of digitized speech samples. The method converts a stream of digitized speech samples to a stream of text and associated reliability measures. A mixed-media data stream is created with the stream of text as a text component and selected portions of the digitized stream of speech as a speech component. The selected portions are those whose corresponding reliability measures fall below a threshold. The threshold can be changed to change the amount of storage or bandwidth used by the mixed-media data stream. The mixed-media data stream can be searched and the results can be spoken as synthetic speech derived form the text component or as speech samples taken from the digitized speech component.
