Using acoustic structure in a hand-held audio playback device

摘要

This paper discusses issues in navigation and presentation of voice documents, and their application to a particular hand-held audio playback device, called NewsComm. It discusses situations amenable to auditory information retrieval, techniques for deriving document structure based on acoustical cues, and techniques for interactive presentation of digital audio. NewsComm provides a portable user interface to digitized radio news and interview programs, and it allows occasional connectivity to a networked audio server with disconnected playback.
