Low frequency groans indicate larger and more dominant fallow deer (Dama dama) males. [PDF]
PLoS ONE, 2008 BACKGROUND: Models of honest advertisement predict that sexually selected calls should signal male quality. In most vertebrates, high quality males have larger body sizes that determine higher social status and in turn higher reproductive success ...

On Short-Time Estimation of Vocal Tract Length from Formant Frequencies. [PDF]
PLoS One, 2015 Vocal tract length is highly variable across speakers and determines many aspects of the acoustic speech signal, making it an essential parameter to consider for explaining behavioral variability.

Field Propagation Experiments of Male African Savanna Elephant Rumbles: A Focus on the Transmission of Formant Frequencies. [PDF]
Animals (Basel), 2018 African savanna elephants live in dynamic fission–fusion societies and exhibit a sophisticated vocal communication system. Their most frequent call-type is the ‘rumble’, with a fundamental frequency (which refers to the lowest vocal ...

Acoustic Measures Capture Speech Dysfunction in Spinocerebellar Ataxia. [PDF]
Ann Clin Transl NeurolABSTRACT Objective Spinocerebellar ataxias (SCA) are hereditary cerebellar degenerative disorders with a common feature of dysarthria, involving impaired phonatory and articulatory control of speech, thereby affecting social communication. In this study, we investigated whether acoustic measures could objectively measure speech dysfunction and identify

A Chinese alligator in heliox: formant frequencies in a crocodilian.
J Exp Biol, 2015 ABSTRACT Crocodilians are among the most vocal non-avian reptiles. Adults of both sexes produce loud vocalizations known as ‘bellows’ year round, with the highest rate during the mating season. Although the specific function of these vocalizations remains unclear, they may advertise the caller's body size, because relative size ...

Timbre perception in violins: spectral and formant influences of string materials in a controlled study. [PDF]
Sci RepString instrument timbre is influenced by a complex interplay of string material, instrument body characteristics, and playing technique. However, the perceptual effects of different string materials and their relationship with acoustic parameters remain
