visualizing soundscapes and quantifying interspecific interactions in forest animal vocalizations using robot audition technology 趙, 皓 鈴木, 麗璽 炭谷, 晋司 松林, 志保 有田, 隆也 中臺, 一博 奥乃, 博 人工知能と認知科学 This paper aims at visualization and quantification of forest animal vocalizations by applying robot audition techniques and ecoacoustic methods. We create a false-color spectrogram of which colors reflect the directions of arrival of vocalizations of birds and cicadas which are localized and separated by HARK, which visualizes directional changes in their vocalizations. We further propose an automatic classification method to classify their vocalizations by using an acoustic index （acoustic cover, CVR）. We conduct a proof-of-concept experiment and analysis of their localized vocal durations, which implies there exist interspecific interactions between birds and cicadas. conference paper 情報処理学会 2022-02-17 application/pdf 第84回全国大会講演論文集 1 2022 475 476 AN00349328 https://ipsj.ixsq.nii.ac.jp/record/220979/files/IPSJ-Z84-1T-02.pdf eng
