摘要： A system enables a user to query for key words and phrases a text document, such as a presentation slide file, and an associated audio stream, such as can be derived from an audio-video recording that is made of a presenter contemporaneously with the showing of the slides to an audience. A graphical user interface is presented in which query results for both the text document and the audio stream are displayed in a time-aligned format, to enable a user to easily and conveniently browse the text document and accompanying time-aligned audio stream based on the key words/phrases.
