*About*



Professor *Marie A. Roch* received her Ph.D. degree from The University of
Iowa. Prior to joining San Diego State University, she held positions at
Florida International University and AT&T Bell Laboratories. Her research
interests are in pattern recognition, particularly as applied to
categorization of audio signals. Her current work is in pattern recognition
for bioacoustics, the study of sound production and perception in animals.

*Abstract*



A fundamental problem in the analysis of calls produced by animals is how
to analyze data whose structures are poorly understood.  We examine this
problem in two different contexts.  In the first, we ask the question of
whether or not recent work on the primate preauditory and/or auditory
cortex can help to determine acoustic landmarks, or segmentations, that may
permit the identification of potential acoustic units, within primate
calls.  The ability to detect such landmarks could provide new methods for
approaching animal communication.  Second, we discuss a method for
providing preliminary assays of the number of marine mammal species present
in environments where species assemblages are not well studied.  Methods of
preliminary assessment can enable better planning for the use of expensive
resources such as visual surveys and provide insights into how animals use
a study area spatially and temporally.
