ORCA-SPOT: An Automatic Killer Whale Sound Detection Toolkit Using Deep Learning.
Large bioacoustic archives of wild animals are an important source to identify reappearing communication patterns, which can then be related to recurring behavioral patterns to advance the current understanding of intra-specific communication of non-human animals. A main challenge remains that most...
