| Outline of Final Research Achievements |
From the singing voice sound signals of wild birds recorded by multiple microphone arrays, we developed outdoor sound environment understanding technology that extracts structured information on what, when and where of bird singing voice events, and that estimates the relationship between wild birds, by integrating robot audition and machine learning technologies. In addition, we have built an outdoor sound environment understanding system for bird song analysis that is easy to use even for a non-expert, and reduce the burden of singing voice analysis work on wild birds that has been performed manually, which resulted in contributing to the field of animal behavioral sciences and bioacoustics.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，従来のロボット聴覚技術と野鳥歌解析技術の欠点を相補的に補うことで，人手を介せずに野鳥の歌声解析に適用可能な屋外音環境理解の枠組みを構築する点で学術的意義が大きい．また，，基礎的な研究課題への取り組みだけではなく，野鳥行動解析の専門家を分担者に招くことで，ユーザ視点での技術課題抽出を行い，必ずしも技術の専門家でない野鳥の行動解析の研究者であっても，簡単に操作できる自動歌声解析システムを構築することで，実作業の負担軽減を狙う点で社会的な意義が高い．
