Current research on primates

Project Details:
With Alexa, Siri and Cortana, voice recognition and control software has become an integral part of our everyday lives. Animal voices also contain a huge number of information about the sender animal, such as species, identity, gender, age, body size, emotional state, diseases and hormone status. Bioacoustics therefore enables the development of non-invasive, time- and cost-efficient, automatic bioacoustic monitoring systems for animals. For this purpose, microphones can be installed recording animals' vocalisations around the clock without disturbing or influencing them. The recordings can be automatically analysed using mathematical algorithms to extract specific information. In addition, psychoacoustic tools can be used to elicit specific positive behaviours. Such bioacoustic tools can be used for clarification of taxonomic questions, to monitor wildlife as well as to improve animal husbandry and thus play an increasingly important role in species conservation and animal management. The aim of this project is to explore the wide range of possible applications and to develop bioacoustic monitoring systems for species conservation and animal management.
