Modelling individual and cross-cultural variation in the mapping of emotions to speech prosody

Pol van Rijn et al.

Summary: This study uses Bayesian modelling to show that individual, cultural, and gender differences contribute more to the prediction of the mapping between emotions and speech prosody than a shared global mapping.

Large-scale iterated singing experiments reveal oral transmission mechanisms underlying music evolution

Manuel Anglada-Tort et al.

Summary: This study presents an automatic online pipeline that streamlines large-scale cultural transmission experiments using singing, revealing the emergence of structures that are consistent with widespread musical features. Individual biases, such as vocal constraints, working memory, and cultural exposure, constrain the evolution of melodies, while social dynamics during cultural transmission contribute to the formation of population-level structures.

Toothed whales use distinct vocal registers for echolocation and communication

Peter T. Madsen et al.

Summary: Toothed whales use their nasal passages to produce sound, which allows them to generate echolocation signals at depths of over 1000 meters. This finding provides a physiological basis for understanding the vocal repertoires and social communication of these whales.

Artificial Intelligence-Based Voice Assessment of Patients with Parkinson's Disease Off and On Treatment: Machine vs. Deep-Learning Comparison

Giovanni Costantini et al.

Summary: This study analyzed the voice characteristics of Parkinson's disease patients using machine learning techniques, and compared different feature selection and classification algorithms. The results showed that both feature-based machine learning and deep learning achieved comparable results in terms of classification, with KNN, SVM, and naive Bayes classifiers performing similarly. The superiority of CFS as the best feature selector was more evident, and the selected features acted as relevant vocal biomarkers capable of differentiating healthy subjects, early untreated PD patients, and mid-advanced L-Dopa treated patients.

OpenSoundscape: An open-source bioacoustics analysis package for Python

Sam Lapp et al.

Summary: Landscape-scale bioacoustic projects are popular for biodiversity monitoring, utilizing passive acoustic monitoring recordings combined with automated detection to monitor sound-producing species' occupancy and phenology. However, technological barriers in data analysis remain a bottleneck for extracting biological insights from bioacoustic datasets. In this study, we provide an open-source Python toolkit, OpenSoundscape, that offers access to automated acoustic detection, classification, and localization methods, along with extensive documentation and tutorials to facilitate the analysis of bioacoustic data.

Deep learning-based classification of posttraumatic stress disorder and depression following trauma utilizing visual and auditory markers of arousal and mood

Katharina Schultebraucks et al.

Summary: Machine learning-based computer vision and acoustic analysis can accurately classify major depressive disorder and posttraumatic stress disorder through free speech responses one month post-trauma, indicating potential for clinical application in identifying digital markers for mental health diagnosis.

Static and dynamic formant scaling conveys body size and aggression

Andrey Anikin et al.

Summary: When producing intimidating aggressive vocalizations, extending the vocal tract can lower voice resonance frequencies to sound big. Static formant scaling conveys smaller size and greater aggression, while dynamic scaling conveys larger size and more aggression. Familiar listeners are less affected by formant manipulations, focusing more on aggressive intent.

Scaredy-cat: Assessment of individual differences in response to an acute everyday stressor across development in the domestic cat

Andrea Urrutia et al.

Summary: This study aimed to assess the stress response of pet domestic cats to brief confinement in a pet carrier and analyze individual differences across different age groups. The results showed that vocalization can be a good indicator of stress response in cats during such everyday procedures, but facial thermography is not sufficiently reliable in this regard.

Gender, Candidate Emotional Expression, and Voter Reactions During Televised Debates

Constantine Boussalis et al.

Summary: The study shows that voters' evaluation of politicians is influenced by the gender differences in nonverbal communication during political debates, with candidates of different genders showing distinct characteristics in facial displays, vocal pitch, and speech sentiment. In German election debates, voters may punish politicians for displaying anger while rewarding happiness and general emotional displays.

Vocal plasticity in harbour seal pups

Laura Torres Borda et al.

Summary: The study reveals that seal pups modify their vocalizations by lowering their fundamental frequency in response to noise, unlike most mammals. Increased noise levels induce the pups to target lower frequencies, while amplitude adjustments seem unaffected.

Variation in the natural frequency of stamens in six morphologically diverse, buzz-pollinated, heterantherous Solanum taxa and its relationship to bee vibrations

Carlos Eduardo Pereira Nunes et al.

Summary: The natural frequencies of stamens in different plants vary, and the vibration frequency produced by bumblebees does not entirely match the natural frequencies of all plants, indicating that pollen release induced by vibrating stamens at their natural frequencies might only play a role in a subset of buzz pollination interactions.
