The Structured Audio Information Retrieval System (STAIRS) project targets environments where workers need access to information, but cannot use traditional hands-and-eyes devices, such as a PDA. The information to be accessed is stored in an information base, either as pre-recorded audio or as text to be run through a text-to-speech engine. Given the inherent limitations of the simple audio interface used in STAIRS, it is important to structure the information base in a way which makes navigation as easy as possible for the user.
