抄録

This paper proposes a method for sharing impression, sentiment, and opinion among people listening to an auditory program together by voice sound effects. We call the system "Radi-Hey." In contrast to the conventional Laugh Tracks played by program staff in TV and radio programs, Radi-Hey reflects the input from audiences themselves. The audiences input their opinion by pushing buttons of several short words (e.g. "oh!", "why?") and can listen to the other audiences' opinion by voice sound effects. Recently, text-based systems (e.g. Twitter) have been used for this purpose, but the audiences are required to concentrate on inputting their message and viewing the others' message. The aim of this paper is to realize high level of simplicity that provides much more prompt and easy sharing of the others' opinion by auditory feedback. We conducted two experimental demonstrations: radio broadcasting programs, and presentations at an academic conference. This paper describes the results showing potential applicability of the system, and the pros and cons for the future development.
