Correlates of Vocal Tract Evolution in Late Pliocene and Pleistocene Hominins
Despite decades of research on the emergence of human speech capacities, an integrative account consistent with hominin evolution remains lacking. We review paleoanthropological and archaeological findings in search of a timeline for the emergence of modern human articulatory morphological features. Our synthesis shows that several behavioral innovations coincide with morphological changes to the would-be speech articulators. We find that signifi…
Rethinking Hominin Air Sac Loss in Light of Phylogenetically Meaningful Evidence
The evolution of laryngeal air sacs in hominins has been a subject of considerable debate, with particular attention given to the inferred presence of air sacs in Australopithecus afarensis and inferred absence in Middle and Upper Pleistocene hominins. We challenge several assumptions prevalent in relevant discourse and assert that (1) while exhibiting morphological similarity, it cannot be ruled out that relationships between hyoid morphology an…
Sketches of chimpanzee (Pan troglodytes) hoo’s
In human speech, the close back rounded vowel /u/ (the vowel in “boot”) is articulated with the tongue arched toward the dorsal boundary of the hard palate, with the pharyngeal cavity open. Acoustic and perceptual properties of chimpanzee ( Pan troglodytes ) hoo ’s are similar to those of the human vowel /u/. However, the vocal tract morphology of chimpanzees likely limits their phonetic capabilities, so that it is unlikely, or even impossible, t…
Correcting the record
The phonetic potential of nonhuman primate vocal tracts has been the subject of considerable contention in recent literature. Here, the work of Philip Lieberman (1934−2022) is considered at length, and two research papers—both purported challenges to Lieberman's theoretical work—and a review of Lieberman's scientific legacy are critically examined. I argue that various aspects of Lieberman's research have been consistently misinterpreted in the l…
Viki’s First Words
It remains an open question whether nonhuman great apes are capable of vocal learning-modification of uttered signals from experience with other individuals.Evidence of such capacities would provide insight into when human imitative abilities-crucial for spoken language-first emerged.However, an important case study with bearing on this topic has been neglected in the literature-that of Viki the chimpanzee (Pan troglodytes).Only a few days old, V…
Motion iconicity in prosody
Evidence suggests that human non-verbal speech may be rich in iconicity. Here, we report results from two experiments aimed at testing whether perception of increasing and declining f 0 can be iconically mapped onto motion events. We presented a sample of mixed-nationality participants ( N = 118) with sets of two videos, where one pictured upward movement and the other downward movement. A disyllabic non-sense word prosodically resynthesized as i…
What's next for size-sound symbolism
This text reviews recent research in phonetic size-sound symbolism – non-arbitrary attributions of size properties to speech acoustic properties. Evidence from a wide range of research works is surveyed, and recent findings from research on the relationships between fundamental frequency, vowel articulation, consonant articulation, phonation type, mora count, and phonemic position, are discussed. It is argued that a satisfactory explanatory model…
