The study of the vocalizations of living organisms (animals, as well as plants and bacteria), also known as “bioacoustics,” has undergone major changes in recent years with the rise of artificial intelligence, which has led to the emergence of highly effective mobile recognition apps for the general public. Progress has been uneven across different taxonomic groups, however, as it depends on the amount of available training data, and has primarily focused on birds, particularly European and North American species. 

A recent area of research therefore focuses on exploring how these vast amounts of animal vocalization data—even if they are unbalanced—can be used to study species that are little known or not yet known.
Louis Airale, a researcher at INSA, provides an update on the issue.
