| Audioconference participants often have difficulty identifying the voices of other conferees, especially in ad hoc groups of unfamiliar members. Simultaneous presentation of multiple voices through a single, monaural channel can be discordant and difficult to comprehend. To address these shortcomings, we have developed the Vocal Village, a communications tool that allows for real-time spatialized audioconferencing across the Internet. The Vocal Village system uses binaural audio signals to present the voices of individual conference participants from different apparent positions in space by adding location cues to audio information. This paper describes our experimental research to determine whether the real-time, “within the head, ” spatialization cues implemented by Vocal Village are sufficient to provide performance benefits compared to traditional, monaural audioconferencing methods. Performance benefits included memory, speaker identification, and participant preference. We also investigated whether providing users with the ability to control the location of conference participants within a virtual auditory space further enhanced any such benefits. The “within the head ” spatialization used in this experiment did not lead to a statistically significant increase in the ability to remember who said | |||||||||||||||||
