Visualizing Voice
Audio communication research to date has been primarily dominated by
work in the areas of speech recognition, transmission and
compression, synthesis, computer music theory, and some music
information retrieval. Looking at many research laboratories and
universities, we tend to find audio processing groups focusing
exclusively on the above areas.
In the area of Human Computer Interaction (HCI), research in audio is
in the minority. For example, there are several textual search
engines and even image search engines, yet barely a voice browser for
public use. One reason is that a voice or audio browser relies
heavily on speech recognition and audio classification which are not
very accurate in general use scenarios. Given different speakers and
different speaking environments, the problem becomes increasingly
more difficult.
In this talk, we are taking a step back and looking at voice from a
simpler perspective. We will show examples of conversational
dynamics, retreaval through the use of a real time voice
visualization on a tabletop, and examples of new interactions by
using this interface as a social mirror.

Karrie Karahalios is an assistant professor in computer science at
the University of Illinois where she heads the Social Spaces Group.
Her work focuses on the interaction between people and the social
cues they perceive in networked electronic spaces. Of particular
interest are interfaces for pubic online and physical gathering
spaces such as chatrooms, cafes, parks, etc. The goal is to create
interfaces that enable users to perceive conversational patterns that
are present, but not obvious, in traditional communication
interfaces. Karrie completed a S.B. in electrical engineering, an
M.Eng. in electrical engineering and computer science, and an S.M.
and Ph.D in media arts and science at MIT.
