Overview of the study of spontaneous ultrasonic vocalizations (USVs) in same-sex pairs of mice. (A) Set-up used to synchronize the spontaneous USVs and behaviors of a same-sex pair of mice using AviSoft and Live Mouse Tracker (LMT). Examples of behaviors automatically extracted using LMT; see definitions in “Materials and Methods” Section and in de Chaumont et al. (2019). (B) Timeline of 30 s of the experiment (day 1, 6 a.m.), with USVs, USV bursts, and the major behavioral events. (C) Screenshots of the online processing application (https://usv.pasteur.cloud) with an example set. Spectrogram and automatically extracted USVs in which each color labels a different USV. The segmentation follows the shape of the frequency of maximum amplitude. USV and USV burst timeline extracted, frequency characteristics. “Download all results” button providing figures and data for each acoustic feature extracted for each voc.
