Non-linear features in vocalizations of birds and mammals (frequency jumps, subharmonics, amplitude modulation, and chaos) typically signify arousal, alarm, or aggression. Presenting people with natural and NLP-enhanced versions of animal calls found that only the addition of chaos raised the sense of alarm in the listeners.

Working on ultrasonic vocalizations? Together, Dr. Elodie Ey and Dr. Markus Wöhr are serving as guest editors for a Behavioural Brain Research special issue on Ultrasonic Communication in Rodents. They are more than happy to learn about your most recent discoveries.

Lapp et al. used autonomous underwater audio recorders and machine learning to study the underwater vocal behavior of the endangered species Rana sierrae. They documented new vocalization types and discovered nocturnal vocal activity. Read here now! https://www.journals.uchicago.edu/doi/10.1086/729422

How the #brain coordinates speaking and breathing
MIT neuroscientists have discovered a circuit that controls #vocalization and makes sure that #breathing is prioritized over #speaking.

#science #neuroscience does that apply to #flute playing too? Might have to read the paper to find out.

Orangutans can change their voices when exposed to smoke from wildfires. Researchers found that the endangered primates produced lower-pitched calls after breathing in polluted air for months. This could affect their communication and social interactions with other orangutans in the forest. #orangutans #wildfires #vocalization https://theconversation.com/to-see-how-smoke-affects-endangered-orangutans-we-studied-their-voices-during-and-after-massive-indonesian-wildfires-208153?utm_source=flipboard&utm_content=HariTulsidas%2Fmagazine%2FArchetypes

The mysterious song of the dinosaurs - BBC Future

"...Her work has led her to a revelation that will shake the ground from under the feet of five-year-olds and movie goers around the world. Dinosaurs almost certainly didn't roar. They probably cooed instead."
