Link-based feature extraction for model-based detection of echolocation calls. Abstract Text:

Mark D Skowronski,M Brock Fenton,

Frame-based acoustical analysis of echolocation calls from bats has recently been proposed to improve the robustness of automated call detection. Statistical models, popularized and honed by automated human speech processing research, learn the distributions of call features extracted identically from short overlapping frames of time. A fundamental assumption is that each frame contains at most one echolocation call. In field recordings of bats, this assumption is often violated by the presence of echoes and overlapping calls from multiple bats, which degrade automated detection performance. Simple rules, based on expert knowledge of echolocation calls, were used to follow local spectrogram ridges and to group ridge points into links. Frame-based features were extracted from the links, which may overlap in time, allowing links to be used in the existing model-based analysis paradigm. Improved performance using links is demonstrated for several pathological cases, including conspecific interaction and high-duty-cycle foraging.
