In Navy command operations, individual watchstanders must
often concurrently monitor two or more channels of spoken
communications at a time, which in turn can undermine
information awareness and decision performance. Recent basic
work on this operational challenge has shown that a virtual
auditory display solution, in which competing messages are
presented one at a time at faster rates of speech, can achieve
large and significant improvements on diminished measures of
listening performance observed in concurrent monitoring at
normal speaking rates with equivalent materials. In the third of
a series of experiments developed to address performance
questions the parameters of this framework raise for listeners,
dependent measures of attention and comprehension were
compared in a two factor design that manipulated how serial
turns among four talkers were organized and their rate of
speech. Although both factors impacted performance, the
resulting measures remained substantially higher than
corresponding measures of performance with concurrent talkers
in an earlier study.
