Augmented intelligibility in simultaneous multi-talker environments

Speech intelligibility can be severely compromised inenvironments where there are several competing speakers. It
may be possible, however, to improve speech intelligibility in
such environments by manipulating certain acoustic parameters
known to facilitate the segregation of competing signals. The
first step in designing such a feature-rich audio display is to
understand the significant elements of human auditory
perception that affect information transmission capacity. We
review a series of experiments to examine the impact of
different audio-display design parameters on overall
intelligibility of simultaneous speech messages and show how
using these features may improve intelligibility.
