    Abstract

    An example of where and how to use non-speech sounds in an interface is described. The role of the sound is to provide an overview or glance for a blind person reading mathematics by listening. The type of sound used to provide the audio glance is the earcon. The algebra earcons were designed using prosodic cues from spoken algebra combined with pre-existing guidelines for earcon design. Three exper- iments demonstrated that listeners were able to recover sufficient information to recognize an expression of appropriate structure. Participants were also able to use the glance to accomplish some mathematical tasks. The prosodic component of speech can be seen to be a useful basis for the design of both speech and non-speech features of an auditory interface.
