| Summary: | "... consists of 57.5 hours of audio recordings of vocalizations by Asian elephants (Elephas maximus) in the Uda Walawe National Park, Sri Lanka, of which 31.25 hours have been annotated. Voice recording field notes were made by Shermin de Silva and Ashoka Ranjeewa, of the Uda Walawe Elephant Research Project. The collection and annotation of the recordings was conducted and overseen by Shermin de Silva, through the University of Pennsylvania Department of Biology, and Institute for Research in Cognitive Science. The recordings primarily feature adult female, and juvenile elephants. Existing knowledge of acoustic communication in elephants is based mostly on African species (Loxodonta africana and Loxodonta cyclotis). There has been comparatively less study of communication in Asian elephants, primarily becuase the habitat in which Asian elephants typically live makes them more difficult to study than African forest elephants. For other current elephant vocalization research, see 'Elephant voices' and the Cornell Lab of Ornithology's Elephant Listening Project. This corpus is intended to enable researchers in acoustic communication to evaluate acoustic features and repertoire diversity of the recorded population. Of particular interest is whether there may be regional dialects that differ among Asian elephant populations in the wild and in captivity. A second interest is in whether structural commonalities exist between this and other species that shed light on underlying social and ecological factors shaping communication systems." -- LDC online catalogue.
