The vocal behaviour of wild indris inhabiting the area near Andasibe was studied by means of all occurrence sampling. We provide a quantitative overview of the vocal repertoire of Indri indri, describing qualitative contextual information and quantitative acoustic analysis for all the utterances we recorded from adult individuals. Other than the song, the repertoire of Indri indri comprises 8 vocal types uttered by the adults. Future studies are necessary to explore whether vocalisations uttered in different contexts have different functions and how these functions relate to acoustic structure.
通过全事件抽样法对生活在安达西贝附近地区的野生大狐猴的发声行为进行了研究。我们提供了大狐猴发声库的定量概述，描述了我们从成年个体记录的所有发声的定性情境信息和定量声学分析。除了歌声，大狐猴的发声库还包括成年个体发出的8种声音类型。未来有必要进行研究，以探索在不同情境下发出的声音是否具有不同功能，以及这些功能与声学结构有何关系。
