Now You Hear It, Now You Don't: Empirical Studies of Audio Browsing Behavior Behavior

We present several studies that investigate how people use audio documents and uncover new principles for designing audio navigation technology. In particular, we report on an ethnographic study of voicemail users, exploring the behaviors and needs of users of current voicemail technology. To constrain design choices for better technology, we then study how people navigate through audio and how they perform basic information processing tasks on a voicemail corpus. Observations and analyses from the user experiments lead to new principles of design for audio document interfaces, which are embodied in a prototype structural audio browser. Specifically, we conclude that the reinforcement of audio memory and appropriate definition of content-based playback units are important properties of interfaces suited to human audio processing behaviors.
