Abstract For more than a century it has been noted that the adult human vocal tract differs from that of other mammals, in that the resting position of the larynx is much lower in humans. While animals habitually breathe with the larynx inserted into the nasal cavity, adult humans are unable to do this. This anatomical difference has been cited as an important factor limiting the vocal potential of nonhuman animals, because the low larynx of humans allows a wider range of vocal tract shapes and…

Predicting strength from aggressive vocalizations versus speech in African bushland and urban communities
TLDR
It is shown that strength can be measured from both speech and roars, and as predicted, strength is more reliably gauged from roars than vowels, words or greetings.
Objective Assessment of Porcine Voice Acoustics for Laryngeal Surgical Modeling
TLDR
This work investigated 17 acoustic parameters before and early after surgery in three Yucatan mini pigs and recommended two, 50% spectral energy quartile (Q50) and Flux, for objective functional voice assessment of pigs undergoing laryngeal surgery.
Rutting vocal display in male impala (Aepyceros melampus) and overlap with alarm context
TLDR
In the studied male impala, rutting snorts within bouts of rutts calls were longer and had higher values of the upper quartile in the call spectra than alarm snorts produced towards potential danger.
Polyphony of domestic dog whines and vocal cues to body size
TLDR
Potential production mechanisms and sound sources for each fundamental frequency are discussed; point to the acoustic similarity between high-frequency dog whines and rodent ultrasonic calls and hypothesize that ultra-high fundamental frequencies function to allow private, "tete-a-tete" communication between members of social groups.
Functionally Flexible Signaling and the Origin of Language
TLDR
At the earliest break of ancient hominins from their primate relatives in vocal communication, it is hypothesize that hominin parents invested more in infants who produced such signals of fitness plentifully, neglecting or abandoning them less often than infants who produce the sounds less frequently.
Primate Vocal Anatomy and Physiology: Similarities and Differences Between Humans and Nonhuman Primates
TLDR
Comparative approaches in vocal anatomy and physiology provide evidence unveiling the acoustic mechanisms for these different vocalizations and promise a better understanding of primate origins and of the possible evolutionary history of human speech.
Savannah roars: The vocal anatomy and the impressive rutting calls of male impala (Aepyceros melampus) – highlighting the acoustic correlates of a mobile larynx
TLDR
This study expands knowledge on the evolutionary variation of vocal fold morphology in mammals, suggesting that the structure of the mammalian sound source is not always human‐like and should be considered in acoustic analysis and modelling.
Sequence and hierarchy in vocal rhythms and phonology

TLDR
It is hypothesized that phonological hierarchy resulted from a marriage of a preexisting capacity for sequential structure seen in other primates, with novel hierarchical motor control circuitry (potentially evolved in tool use and/or musical contexts), and paved the way for phrasal syntactic hierarchy.
Encoding of Emotional Valence in Wild Boar (Sus scrofa) Calls
TLDR
Investigating vocal expression of emotional valence in wild boars found that screams and squeals were mostly produced during negative situations, and grunts during positive situations, which suggests that wild boar can vocally express their emotional states.
