MarmAudio: A large annotated dataset of the common marmoset vocal repertoire

We present here MarmAudio, a database of common marmoset vocalizations, which were continuously recorded with a sampling rate of 96 kHz from a stabulation room housing simultaneously ~20 marmosets in three cages. The dataset comprises more than 800,000 files, amounting to 253 hours of data collected over 40 months. Each recording lasts a few seconds and captures the marmosets' social vocalizations, encompassing their entire known vocal repertoire during the experimental period. Around 215,000 calls are annotated with the vocalization type. We validated our dataset by sampling 700 representative recordings and cross-examining them with four experts.我们在此介绍MarmAudio，一款普通狨猴发声数据库。该数据集的音频以96 kHz的采样率连续录制自一间圈养笼舍，该笼舍内设有三个饲养笼，同时饲养约20只普通狨猴。本数据集包含超过80万个音频文件，总时长达253小时，采集工作历时40个月。每条录音时长为数秒，收录了狨猴的社交发声，涵盖了实验期间已知的全部发声库（vocal repertoire）。其中约21.5万次叫声已标注其发声类型。我们通过抽取700条代表性录音，并邀请四位专家开展交叉复核，完成了对本数据集的有效性验证。
