Analyzing Animal Calls: Segmenting Calls Into Acoustic Units and Identifying Species Groups

Speaker: Marie A. Roch, Professor, Department of Computer Science, San Diego State University

Host: Dan Blumstein, Department of Ecology and Evolutionary Biology, UCLA

A fundamental problem in the analysis of animal calls lies within analyzing poorly-understood structures of recorded data. Roch will examine this problem first by asking whether or not recent work on the primate pre-auditory 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, Roch will discuss a method for providing preliminary assays of the number of marine mammal species present in environments where species assemblages are not well studied. Roch believes methods of preliminary assessment can enable better planning for the use of expensive resources such as visual surveys, as well as provide insight into how animals use a study area spatially and temporally.

Light refreshments will be served.
