Abstract

The interest in ecosystem conservation is growing with many remedial policies sought and implemented. In particular, the public recently has perceived awareness that it is essential to eradicate exotic invasive species and protect endangered species because they destroy the food chain and the ecosystem. With the recent advancement of deep learning-based technologies, several studies on acoustic signal classification have taken place, but the studies on animal sound classification considering actual noise environment are still scarce. In this paper, we propose a data augmentation scheme for training by setting up an experimental environment that includes the sounds of exotic invasive species, endangered species, and realistic environmental noise. With the proposed augmentation scheme incorporating more real environment under various SNR conditions, we construct the training set, validation set, and test set to classify the animal sounds. For validation, we compare the performances of various deep learning-based methods used in signal classification tasks by employing the constructed dataset.
