Abstract

An innovative non‐voice sound recognition system based on a new similarity scale called the geometric distance has been developed. It has been purpose‐designed for searching terabyte‐sized files for wildlife recordists. Initially this method has been used for analyzing continuous recordings of rare parrots in Australia. More recent work has extended its applications to other birds, bats, frogs, and marine animals. The software can search for multiple reference sounds and multiple species in a single pass. It has been demonstrated to achieve recognition accuracy comparable to a human expert.
