This symposium will focus on signal processing related to animal sounds and monitoring in domestic situations and in unstructured, wild conditions. Multiple research groups have begun to explore using signal processing of the sound scape to provide information about animal activity, environmental conditions, or animal health and welfare. This area of research builds on a variety of signal processing and machine learning theory, but the challenges are significant since the signals of interest are often buried in noise that is both varied and often similar to the signals of interest. Furthermore, the signals of interest are often expressed in conjunction with many other similar signals creating a chatter problem.
